Linear workflow under Linux

[Metzger]

Is there going to be a fix for Linux so you don't have to add a gamma correct node of .455 to non linear texture maps?

Also, can anyone recommend a way to keep the blacks on the dirt shader unaffected by a linear workflow?

Thanks

Ironically, for your second problem it would be best to use a gamma correct node for the blacks in the dirt shader.

If you attach the VRayDirt texture to a VRayMtl material, it will be gamma-corrected as part of the material, like everything else (which is not entirely correct, but is mostly ok).

If you use it as a separate pass, then it should not be gamma-corrected, as it is already in linear space.

You could probably disregard my comment, I don't think I was on the same page!

"keep the blacks on the dirt shader unaffected by a linear workflow"

This threw me off.

I thought the whole point of the linear workflow under color mapping was to actually automatically place a gamma correct on non linear texturemaps.

It does something a little different; it adds gamma correction to the color slots of the VRayMtl material, regardless of whether they have only colors, or textures. This does not affect bump maps, normal maps, or environment/background maps or maps in any other materials (e.g. the blend maps in VRayBlendMtl are also unaffected).

I could swear that option did nothing to the color of my color images plugged into the color slots of VrayMTL. Is this broken under the Linux version still?

My versions are as follows:


V-Ray Standalone, version 1.5.01 for x64
V-Ray core version is 1.90.02

Thanks for the quick replies. Also, I was wondering one more thing. If camera projected textures that are texture referenced, will they still hold texture reference positions if a proxy per frame is created for the geo animation? I know texture referencing from camera projection was fixed, but I haven't tried it for proxy geometry.

Thanks!

It's working on both Windows and Linux from what I can see; for the proxy geometry, it should work fine with camera projection, but I have to test it to be sure.
