^^[SM5] Sampling a virtual textures is currently not supported when connected to the Opacity Mask material attribute^^

Mask sample type was set to Virtual Linear Colour as well as ticked off sRGB. I literally don’t know what I did wrong…

Please advise!!!

I’m not amazing with the material editor, but I suspect it may simply mean that it doesn’t like that extra pin plugged into the grayed out “opacity mask” option.

I tried to plug a single texture sample and it works. But the error came up when I used virtual texture. Properly opacity map simply not support virtual texture?

I have the same probleme. Im trying to use UDIM map, but its not working. If i put to alpha channel and after this i use into opacity its just crashing my UE4
