Megascan Textures and forever Loading bitmaps

[davidyannick]

I'm trying Vray, I have a RTX 3090 - i9 10900k - 128Go RAM, and when I try to render 3D objects with 4k or 8k textures with CPU it's very fast(few seconds), but as soon as I switch to RTX, render stuck at "Loading bitmaps" for sometines 10 minutes ??? Any idea please ?
Thx
