Hi there,

I've tried to export a vellum fluid simulation saved as bgeo.sc to unreal engine using VAT export, but it gives me an "error rendering child" related to the Lookup render.


But it works if I bypass the File Cache and uncheck "Input Geometry Is Cached to Integer Frames" option inside the VAT properties.

I have no idea what I'm doing wrong with the File Cache to get this error in the VAT export, I only have checked the "Initialize Simulation OPs" option, the rest is by default.

P.S. I'm using 19.0.383



Thanks in advance!

Daniel.

Hey,
There are two ways so get rid of this error.

Reduce the amount of vertices,
or
Increase the Lookup Table Width.
