Particle Flow error

I have imported a PFlow into a new scene, and when I try to render I get the following errors.

error:UNHANDLED EXCEPTION: Calling EvalWorldState() for node ‘PF Source 01->Event 01’ at time 7488 Last marker is at .\src\staticmeshinfo.cpp, line 467: StaticMeshInfo::buildNormals()

error NULL mesh in StaticMeshInfo::compileGeometry()

Why is this happenening? and how do I fix the error without rebuilding the Pflow from scratch?

Which V-Ray version is that?

Best regards,
Vlado

It was RC3, but the error was my fault. I had a PFlow system without its emitter.

I guess vray was trying to create the mesh for the pFlow but couldn’t as there wasn’t any particles created. ?

Yep, although crashing is probably not the best way to complain about it; I’ll try to correct this.

Best regars,
