Particle cache and XSIBatchserver 2005-06-24 - By Morten Bartholdy
Back
Eric, you need to open the render tree and swap the default
Particle_sparks/Particle_vol_sparks shader with the Particle_Renderer.
Weird leftover, but I have had succes with rendering this when I had big
problems with the Particles suddenly deciding to recompute even if I was
using Standard Cache. I have not tried the particle player with XSIBatch but
I supose you can let us know how it works.
Best regards
