Vray 5 Opacity Map not correct in viewport

[simona.b]

Hi,
I have Vray 5 hotfix 1 installed on 3ds Max 2021, noticed that an opacity map applied to VrayMtl doesn't look correct when you "invert" the bitmap under Output parameters. It still renders correct, but viewport preview only shows non-inverted version.

Hi,

It's a 3dsMax thing actually, you will find that the Inversion doesn't get displayed correctly even with the Standard material and Realistic viewport shading with maps. However, we will see if we can make it work for our V-Ray Bitmap node.
