V-Ray Tuner 4.5: Now With Automatic Light Select RE Generator for Lights

In older versions of V-Ray Tuner, I had a script that would spit out individual renders for each light, sun/sky, etc. so you could adjust the lighting in Photoshop or Nuke later. Well since Chaos Group updated the Light Select render element to include global illumination, that script is no longer efficient since the Light Select method lets you render a single frame and get all those nice separate light passes without re-rendering. So I updated V-Ray Tuner to include a script to auto-generate a Light Select render element for each light in the scene (it also prompts you to make a dome light for to host a sky as texture since that's required as a workaround):

That older script has the advantage that it works with materials with emission and mesh light materials though so I am keeping it around. Go get it.

V-Ray Tuner 4.4 Now Available

The latest version of V-Ray Tuner adds some things that people will likely find useful. From the changelog:

Sampler Toggle in Render menu to change between adaptive subdiv and progressive sampler types. Shows feedback in Script Editor line.

Active sampler type is printed to Script Editor with other info when you hit Refresh.

Added Adaptive Subdiv sliders to DMC and Adaptive Subdiv Antialiasing section of sliders.

Optimize settings button now sets sampler type to Adaptive Subdivision, which is best for bucket DR rendering.

VFB snapshot now works correctly when you have VFB panel loaded.

Fixed V-Ray Tuner Presets to now store/restore Progressive Render and V-Ray RT slider settings. Also added support for new Adaptive Subdiv sliders.

"Move current scene images from images/tmp to images" script added to Utils menu. I got sick of doing this manually – it's also a good way to ensure that a render you like doesn't get overwritten by a temporary render. It prompts you to confirm if this would result in a clobber of other files of the same name.

This last feature is the first script I wrote that requires the "vraytuner_pycomponents.py" script that is now included with the main MEL script. Install it to any scripts folder with the MEL file but it doesn’t need to be loaded manually – it’s called from the main vraytuner script. I'll likely be adding things to this in the future since it's just easier for me to make Python scripts for new things. I'd love it if V-Ray Tuner magically converted itself to Python but it's almost 8000 lines of code so that ain't gonna happen.
