Nvidia rtx 4090 driver issues? Dec. 14, 2022, 6:04 p.m.

Yes this is still a thing, certain pockets of vellum still crashes on newer nvidia drivers. would be lovely to get this fixed! Also maybe consider outputting a Houdini 19 daily with these fixes as people are starting to run into vellum problems there as well, as 4090s become more and more available.

Crowd to Unreal Engine and VAT 3 problems Dec. 6, 2022, 6:13 a.m.

I am currently running into a wierd issue using 19.5.435 VAT 3.0 and UE 5/5.1

I am isolating just 1 crowd agent for the sake of testing, unpacking it so its just geo and using the Soft body preset to export the VAT. it "works" as in it loads and run in UE, but it looks not quite right and I cannot figure out why.

I have attached a few videos of different attempts and you can see how when the model is lying still ish, the points move in very odd ways, like a shimmer or just noisey. gives it this jagged look, I have tried everything from 256 to 8k in texture size and it seems to make no difference.

any pointers on why this stuff would happen would be most appreciated.

P.S. when I use a simple object like an animated box, it all seems to work fine, so I'm wondering if its something about the mesh or model or..?!

Nvidia rtx 4090 driver issues? Oct. 17, 2022, 10:16 a.m.

It would be great to know if this is one Nvidia or Sidefx to update / fix?
Is it because Nvidia updated some OpenCL stuff for their omniverse and now houdini needs to be updated too? or did Nvidia straight up break something that hopefully gets fixed in the new driver?
