Color in 2sided

Hi Vray community,

I’m on vray 7.2 with 3DsMax 2024, and a experiment an issues with Vray2Sided : With a Vraylight in Dome light (with VrayBitmap or not) the frontside appear with yellow tint.

Tested with 7.1 too, with basic VrayMtl, basic Vray2Sided, and double check the color in transparency with a perfect grey.
I’m working in ACEScg colorspace.

The issues disapear when the light turn in sphere or plane… But always in dome mode !

Thanks.



Hard to say from the screenshots alone. Mind if you attach a simple scene?

Yes,
I have created a simple scene : I’ve opened 3Dsmax, create two planes, put 2sided on, with basic VrayMtl, and add vraylight in dome… that’s all.

Thanks.

Thanks for the provided scene. The “Material 25” shader seems to have a very slight fog color (1, 1, 0.999999), which gets rounded to 1 in the UI. It also has a translucency color of (1, 1, 0.9999992, 1) and a coat color of (1, 1, 0.9999992, 1). I am not sure how that happened, but if you pick another color and then manually set the colors to white (1,1,1), the tint will disappear.

Right, thanks !
I find it’s the color management in 3dsmax, with OCIO… I’ve changed the mode and it’s full white and good !
Thanks.
