Re: Particle Blob

["Byron Nash" <byronnash(at)gmail.com>]

Sorry to dig this thread back up. Has anyone made any more progress getting reflective and refractive properties onto the blob shader? XSI crashes and/or will not render when I plug a "Refraction" node into the blob shader. I will accept the "Refraction Diffuse" however. I also tried the legacy shader route but I couldn't get XSI to render the particles.

Thanks.
Byron

hmm well i get error message and no crash when i try environment option

but normal raytracing enabled 'appears' to be working. heres an alleged
