World position offset with displacement in houdini

[dgani]

I'm trying to animate a large group of background plants at render time by using displacement. This shader is working, but the meshes appear to be tearing or getting broken normals in the render. Has anyone else tried to do render time animation of foliage like this?

Turning on "keep continuity" doesn't change anything.

Thanks for reading!

I'd like to hear an answer on this as well. Thanks

1. Does "Cache Normals" help?
2. Does unchecking "Use Global Settings" and using another settings help?
3. Does Generate "Pre-tesselated" helps?
4. What is in the normals render element?
5. Could you send me that scene?

Thanks, I'll start going down the list. I've attached the scene here

Could you check if result using "Render As Subdivision" will suit for you?

[dgani]

Yep, that fixed it! Thank you!

Well, I still want to figure out if it's possible to not use subdivision, but I guess this could be a good workaround for now.

It looks like we may need to stop subdividing those plants - render time went up a lot in heavy shots. Any ideas?
