XSI 2: Particle render bug (multithread render)?

[jeanjaqs]

The 'Simulation_PType_Steam.scn' sample scene included in XSI2 has particles with a .tif bitmap associated.

When this scene is rendered in multithread mode (activated with 'ip:port -thread 2' in the ray3hosts file for 2 cpu system), the secondary thread doesn't render the particle with the bitmap while main thread does.

If the scene is rendered in single thread mode (1 cpu), particles are rendered ok (showing the bitmap).

Is this a bug?

Right!!!
multithread mode (activated with 'ip:port -thread 2' in the ray3hosts file for 2 cpu system) include too many problem

for instance
particles with sparks shader do not render fine
Rendermap crash
NURBS objects Hair emission can not connect weight map
MultiSurface only in [0]subsurface emission Hair

What are you talking about? There is no such thing as "multithread mode (activated with 'ip:port -thread 2' in the ray3hosts file for 2 cpu system)."

XSI 2.0 uses both processors without you having to set any thing up manually. (Unless you are not using a legitimate version, in which case it will only use one processor.) You only need to use a ray3hosts file when you are rendering with more than one computer, not multiple CPUs in a single computer, who knows what problems that will lead to.
