Hi all,

I'm new in Houdini and in the RBD nodes. I have a wrong result with my vertex animation texture in Unreal.
After multiple test, i know what is wrong and didn't function.

I have a basic Pig Mesh who is detroyed by a RBD material fracture node, and when i haven't a custom collision in the Rbd bullet solver node, the animation is played well, but after i connect my animated ball to destroyed this Pig, my result is fuck up in Unreal.

Do you have any technic to have a custom animation who collide with the mesh,that we could export in a Vertex animation texture ?

You could find my files and my exports in attachment.
Thank a lot

Nath

Hey Nath. It looks like you're using the older version of the VAT ROP. First thing I'd suggest is change it to v2.0 by right clicking on the ROP > Actions… > Change Type. And choose Labs Vertex Animation Texture v2.0. Turn off Keep Name, Keep Parameters and Keep Network Contents.
You can find more info about the latest VAT ROP here:

Then finally, the ROP requires pivot, rest and orient attributes. On the rbdbulletsolver go to the advanced tab, expand output and add orient rest pivot to “transfer attributes”.

Hey mikelyndon-sesi, thanks a lot for your answer and your links. It's works perfectly now !
