V-Ray Tuner 3.6 Posted for Download
Slowly getting my brain to function after the loss of my dad and put up new V-Ray Tuner version with some features:
- Reload All Textures: reloads all…..wait for it….. textures.
- Polygonal Displacement Preview added to material menu.
- Toggle Displace As Diffuse script added to Materials menu.
- Increase viewport2 preview texture size script added to Materials menu.
- Lowered physical camera F-stop slider min to 0.01
- Fixed Material Swapper script. It could fail if you didn’t have displacement attached to the original material.
- Added the ability to reapply original material to V-Ray/Maya Material Swapper script.
- Dock Maya Render window script added to Render menu. This prevents it from popping up every time you want to just render using the VFB.
- Apply any object’s subtexture as diffuse toggle - script added to Materials menu. This is similar to the apply displace as diffuse but populates a list from the files attached to the mesh’s shader:
I’m working on getting it to work with V-Ray Blend mats as well. Thanks go out to Andrew Hazelden for the list population code. That saved me tons of work.
- Initial V-Ray Tuner/Refresh info that is shown in the command line feedback now includes your scene’s preview resolution.
If you enjoy using V-Ray Tuner, call your parents and tell them you love them.
A Script to Toggle Displacement as a Surface Shader Diffuse in Maya
If you tweak cage meshes in Maya that are to be subdivided and displaced, you end up worried about a couple things: what will happen to your seams when you do that tweak and what is the displacement going to do when applied to your tweak? As I mentioned in an earlier post, you can do a polygonal displacement preview but sometimes it is sufficient to just preview the displacement on your cage mesh in Maya. So I wrote a script that will be part of the next version of V-Ray Tuner that makes a temporary surface shader and applies the displacement map for the currently selected mesh as the diffuse colour. If you run it again, it switches back to the original shader and deletes the temp surface shader – no crap left around.
One nice feature of this script is that it uses the same file node as your material so even if you change the link to a new file you might have touched up, it will update the original shader’s displacement file node even though you are previewing the surface shader. I hope you find it useful.
Grab the script here. It works with all renderers.
V-Ray Tuner 3.5 Posted for Download
The latest version of V-Ray Tuner is out now. 3.5 includes some
- Optimize button’s V-Ray dynamic memory adjustment now works automatically with versions 2014 and over. No more manual setting of RAM amount needed.
- Added an SSS Prepass Rate Switch script to Materials menu. This dialog prompt lets you set the prepass rate for all SSS materials at once so you can dial it down to something like -1 for draft renders and then put it back up to 1 or something like that for final renders. Can save a lot of time. Just enter the negative or positive integer value and the script sets all V-Ray SSS mats at once.
- Removed Disable Texture Filtering script from Materials menu. It turns out that disabling texture filtering will load the full resolution textures (no matter how small it is in the scene) so it can use a lot of memory needlessly.
- Per-light exposure tweak fixed for non-VRay lights.
- Select Z-Depth RE added to Utilities. Saves digging into render settings to adjust Z-Depth parameters.
- Select V-Ray Sky added to Utilities. Same as above but for sky node.
- Start/Stop IPR Render menu items added to RT menu so you can start V-Ray RT from there.
- Render log/console script in Utilities menu now opens the vray4maya_renderlog.txt in OS X’s Console.app
- Make Frustum script added to Utils menu. It makes a Nuke style 3D frustum for selected cameras and parents it under your camera node:
- Split Utilities and put render stuff into a Render menu because there was too much stuff in the Utilities menu before
- Replaced “D” displacement toggle checkbox with “PL” for prefilter light cache since it’s more commonly used.
- Per-light render script now has a simple interface and toggle for VFB curves and levels. The “Proceed to next light” option is used to cancel renders. If you uncheck it and hit escape, it won’t proceed to the next light. This prevents hammering cancel to stop it from rendering all your lights if you want to stop the operation.
V-Ray Tuner 3.4.2 – Another Small Update
Just did a few fixes and small additions to V-Ray Tuner. Changelog lady:
Tumblr is all bunged up so read the changelog on the Creative Crash page.
Small Maintenance Update to V-Ray Tuner for Maya 2014
V-Ray Tuner 3.4.1 posted for download. There’s not too much new here but there’s an important fix for the Optimize button script for Maya 2014. Maya 2014 has a bug that returns the wrong number for RAM amount for “memory -phy” so, if you’re running 2014, the script asks you to enter your memory amount in GB. Otherwise, the only other new addition is that I’ve added Point Light support to per-light render script.
V-Ray Tuner 3.4 Update Releasededed
This is not a huge update to V-Ray Tuner but it brings a few fixes and features that affect various things. Here’s 3.4 changelog:
- Composite pre-bake diffuse colour with V-Ray Dirt RE:
- Changed DaveBake420 10% value to be 512x512, instead of 409.6x409.6 (10% of 4096).
- Attach Cam button now prompts you to add and enable physical cam attributes if you don’t have them already on the selected camera. If you select no, it will still hook up the overscan setting.
- materialDropper and materialCopyDropper now work on face-level selections as well as with objects.
- Optimize button now sets memory setting (sys_rayc_dynMemLimit) to 80% of total memory in your system.
- Fixed material worker layer script. I had started to implement a new feature but forgot to finish it so it was broken for a couple versions.
- Per-light render script now does solo light re-renders. If you have a light selected and run per-light render, it will only render that selected light:
- Small fix to per light exposure light tweak - it could fail to properly detect your light selection before.
- Revert To Saved Document script added to Utils menu.
V-Ray Tuner 3.3 Gets the Hot Feature Injection
I am pretty happy with the latest V-Ray Tuner 3.3 update. It adds a number of features that I now use constantly and I think they’ll be pretty popular. Here’s a break down of what’s new in 3.3:
- Optimize setting now prompts you for core count when distributed rendering is on. Use the max threads of any of your machines that are active in the render. If you have a local machine that’s eight cores (or four hyperthreaded) and a slave machine that has 16-cores hyperthreaded (32-threads), enter 32. Disable DR and click Optimize again and it will properly set the thread count for the local machine only:
- Added a disable texture filtering script to Materials menu so you can turn off filtering for File nodes all at once.
- DaveBake420 script has got a big uprade in 3.3. Now has an option to comp your Dirt V-Ray pass with the diffuse channel after baking. Good for adding grittiness to diffuse textures with little work:
- Fix Light Size button replaced with create Sun & Sky script. V-Ray no longer has issues with manually-scaled lights so the script is no longer necessary.
- Sprite Maker script now works with currently selected camera, not just main persp camera.
- New Material Swapper script that should replace the “Maya and mental ray Mat to VRay” script for conversion of Maya materials to V-Ray mats and back. Paul Dreisen graciously provided the original script but I tend to convert more between Maya’s materials and V-Ray than mental ray mats and I wanted to beef up the accuracy of conversion that’s done by the script to save time. This script does a really good job of converting things like Phong materials from Mudbox FBX files to V-Ray, with all channel-mapped texture intact. If you want to go back to Mudbox but you’ve set up a V-Ray Material, it will swap the V-Ray Mat for a similarly set-up Phong, Lambert or Blinn mat. It’s also great for mass-converting Paint Effects polygon materials. Here it is in action:
It’s not shown in that video but the release script now has a palette with an option to keep the original swapped-out mats after conversion.
As always, let me know if there’s anything you want added or tweaked in V-Ray Tuner.
V-Ray Tuner 3.2 – Small Maintenance Update for Linear Workflow Tools
I’ve updated V-Ray Tuner with some more robust changes to the handling of materials and textures when using the Gamma Correct Me script. It now works with any type of texture and it no longer gamma corrects a node if it’s parented to a gamma correct already. It’s more foolproof overall and, as always you can do the degamma on textures or the parent V-Ray materials:
- Edit all selected images script to open all selected file nodes in image editor
- Shellac me now enables shadows for both base and coat materials. I always use this, so if you don’t want this on, remove these two lines from the script: setAttr ($currentSurfaceShader + “.bumpShadows”) 1; and this: setAttr ($fresnelCoater + “.bumpShadows”) 1;
V-Ray Tuner 3.1 Adds Basic File Texture Manager and Other Features
Updated V-Ray Tuner with some things I think many people will find helpful:
- Select objects with selected materials script selects objects, not just faces, for selected material:
- Added feature to Material Copy Dropper: if only one object is selected, it will duplicate the material and upstream nodes and apply it to the selected object
- Gamma Correct Me now gamma corrects connected subtextures as well as swatches for V-Ray Materials:
- Gamma Correct Me dialog automatically selects the menu item for the item type you selected: file or V-Ray Mat
- Added Gamma Correct Me support for VRayFastSSS2 mat. Works for both swatches and attached file nodes
- Added per-light exposure tweak support for V-Ray Light Materials, V-Ray Materials (self-illum slot is adjusted by exposure), Sun and Environment (Sky).
- Added script to select and copy files that are outside project sourceimages folder to sourceimages and relink them:

It’s Your Maya Script Birthday! V-Ray Tuner 3.0 and Facer 2.8
So, after finishing up some jobs and adding some features to these while working on those contracts, I have rolled in some new things to both V-Ray Tuner and Facer. There’s quite a bit that’s added in each and I’ve included some features of one script in the other just because it made sense for things like UVs, which affect both modelling and rendering.
V-Ray Tuner 3.0 new features:
- Material Copy Dropper in Materials menu. This is similar to the Material Dropper script that lets you apply materials from the first selected object to all the subsequently selected objects but this applies the copied shader from a “Duplicate Network” operation so you can use the source material as a starting point for your next object’s material:
- Stored Texture Reloader. I got tired of having to dig down to a file node when doing external tweaks on a texture file, so I added this. It lets you store the working texture file and refreshes it when you select the menu item again. Select a new File node and it will replace the stored texture as the one you want to refresh:
- Gamma Correct Me now has an interface to select the type of thing you want to degamma for a linear workflow: colour swatches of your selected material(s) or selected texture(s). This way, you can just avoid gamma correct nodes, set your swatch colours and just do all the gamma correction in one step with this.
- Gamma Correct Me script for textures now uses V-Ray attribute for File node to avoid black textures in viewport. It uses a Gamma Correct node for everything else and works with ramps, blendColors, etc. Here’s a demo of those last few features in action:
As you can see from the way I start a linear workflow scene from scratch, this lets you click the LWFMe button to initialize all the right parameters for a linear workflow but then you disable the LWF toggle to work with manually linearized swatches. The Gamma Correct me script for swatches currently only works on V-Ray Materials (not FastSSS2, Light Mats, etc). I’ll add support for those later.
- Added Brute Force/Brute Force and Light Cache/Light Cache presets to GI modes dropdown.
- Added Transfer UVs script to Utils menu. Select source first and all targets after that and run script to transfer UVs.
- DaveBake420 script now automatically enables texture baking render settings and then disables them on completion
- Select Missing Textures script added to Materials menu. Checks if any of the links to file nodes are missing links and selects them if they are.
- Added 200% upres option to the R% render preview size. I’ve found I wanted this occasionally. This doubles the actual resolution, not just the preview resolution so it will ask for confirmation. See these last two demoed:
Facer 2.8 new features
- Better UV Checker tool in Materials menu. See below.
- Better UV checker tool. I made a custom colour UV grid and the script will prompt you to download it automatically if it can’t find it in your home script path. Because Windows lacks a command line download tool like curl, I had to use Python and it might need a couple tries to grab the file. See it in action:
- UV Snapshot tool to launch a temp snapshot file. I find I never want to keep this file, I just want to open it in Photoshop to put on another texture, so this saves the snapshot to your OS tmp folder and opens it in whatever app is set to open PNG files.
- Cull Toggle, toggle normals, toggle face centres and toggle BBox now disables or enables normals for all selected objects instead of simply flipping the individual object’s normal state (leaving you with a mix of normals on/off):
- Added options dialog to Replace All With Last Selected script. Lets you use instances instead of copies and select scale of copies to keep source or target scale.
Often when you work, you’re lazy about using instances to save memory so this lets you just do it all in one step for big memory savings at render time. When you render a bunch of those heads with copies, it takes over 6GB of memory (click for high res):
Use the script to replace those copies with instances and your render memory usage drops to 1.6GB (click for high res):
So, I hope you enjoy these updated scripts – the download links are in the new feature headers for both. If you get a lot of use out of them, maybe consider picking up a copy of the ePUB, Kindle, iPad iBook or PDF version of 101 Autodesk Maya Tips, which is still only $2.99. In the words of Yakov Smirnoff – IS BARGAIN!
