Using VrayUVWRandomizer for displacement creates bad seams

[stevesideas]

I'm using a displacement map from Quixel that naturally tiles but I do not want repeating tiles so I'm using VrayUVWrandomizer as the mapping source in the vraybitmap. Even with blend at 0.5 the seams are really bad.

I tried turning on keep continuity and reducing the filtering of the bitmap to 0.01. Nothing seems to work.

Is there a solution to this?

Reducing the blend to 0.25 helps but there are still very visible seams! Could really do with some help on this asap please

Is this on the GPU? Displacement with UVWrandomizer is still pretty hit and miss over here. With or without stochastic tiling. This looks to me like a similar problem as this: https://forums.chaosgroup.com/forum/...randomizer-gpu

I have some solution for this, but it’s not in the nightly builds yet. If you email me to vlado@chaosgroup.com with the version of 3ds Max that you are using, I can get you a build to try out (it will only work with the 3d displacement method though).

Best regards,
Vlado

Thanks Vlado. I'm emailing now

Would love to test this too. Emailed a few days ago...
