Where is "GI Post processing"?

Where is "GI Post processing" at V-Ray 3 SketchUp?

It changes only into control by Override Mtl?

Sorry for replying with such a delay!

All of V-Ray's render setting parameters have been optimized in the new version, including those no longer visible in the UI. Other parameters were hidden due to being part of legacy plugins or simply outdated. You can read more about these changes here

Did you frequently use those parameters?
Within the Frame Buffer, you can use the 'Color Corrections' button located at the bottom-left corner to edit the color settings even while the render process is ongoing.

Regarding the last question, what do you mean 'it changes only into control by Override Material'?

"GI Post processing"(Saturation) is used in order to mainly control color breeding of GI.
Color correction of the frame buffer can not control only the GI illumination.

Therefore, in V-Ray 3 SketchUp, V-RayOverrideMtl must be used for controlling Color Bleeding.

It is not a parameter which should be hidden.

Sidenote: at the Vray side of the plugin also missed.

The GI post-processing is not something natural and should be avoided.
That is the reason why we did hide the options from the UI.

If there is undesired color-bleed in the scene it should be addressed in a different way:
The color saturation of the materials causing the color bleed should be decreased.
For realistic materials the color 'saturation' should not exceed 80/85%.
As a side note, the same applies to the color 'value'.

Using a material override is also an option but it should again be avoided since it isn't natural.

Sounds like we have a render police now and artistic freedom isn't liked anymore. I afraid my clients will not like it. Some times a little simple fake helps to get a better look than "natural". The human eye is filtering colors in the real world and some times it helps to use a fake for a rendering to match the natural impression of the human mind.

Will the 3dsmax user get a simplified Vray plugin too?

Probably expected to be solved by the new VFB in the future.
(composite and modification of GI elements)
