Someone requested my handy V-Ray Tuner Presets setting feature for the soon-to-be-outdated V-Ray Tuner for V-Ray 2.4 so I added that feature to the 2.4-compatible version that’s on Creative Crash. This will be the last update to V-Ray Tuner for V-Ray 2.4 so be sure to grab it now if you’ll be sticking with that version for a while. If you haven’t seen the V-Ray Tuner Presets in action, here is a rundown of why it’s handy, from the changelog:
Added V-Ray Tuner Presets manager for render settings in the Render menu. This is a nice way to create render presets that don’t affect EVERYTHING like Maya’s render presets do. This only affects the toggles you see represented in the V-Ray Tuner interface, so you can use a universal “Draft” setting for different resolution documents and click the load for final render settings that you prefer and only have the relevant quality features changed.
Here it is in a workflow:
Otherwise, if you’re using the V-Ray 3.0 betas, be sure to check out the awesome GGX-based BRDF that’s been added to the V-Ray 3.0 release candidate:
If you want to read up on GGX, there are good examples by a talented coder who wrote his own GGX shader here – he sums up GGX like this:
It is very good for use with more accurate metals.
