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 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.
