Greetings to all!!!!
Do as shown in the screenshots below:
!!! Please note that a change in the right field «UI schemes: », may result in a change in the interface panels !!!
If you are happy with everything in the interface, it is better not to change in this field, there is nothing.
Then, 3ds Max prompts you to restart it for the changes to take effect:
After restarting the program, call the Material editor, now all the materials it VRayMtl with different color Diffuse:
If after restart "balls" in the material editor have become darker than usual, then you change the default value range of 3ds Max and do just steps to the material Editore, got rid of it again at the default. In this case, go to the "Gamma and LUT" and resume tick "Affect Color Selectors" and "Affect Material Editor" in the segment of "Materials and the Colors" .
That's all for me personally so really convenient, since I work with V-Ray.
I think it will be convenient to you😉
