Maxwell Render | Official public forum

Hi, thanks for the plugin but I have a problem rendering simple Pyro Smoke with Maxwell and Houdini.

I'm using Houdini 13.0.343 with Maxwell 3.0.1 (Build from today) and the Plugin 3.0.0.1 on OSX.

Pyro Smoke works in the IPR Window but I can't render it with the Maxwell ROP. MXS export gives me the same results as rendering directly with the ROP.

Smoke Maxwell ROP



Houdini Shell shows this errors:

Maxwell_IPR(1065,0x133f3e000) malloc: *** auto malloc[1065]: error: GC operation on unregistered thread. Thread registered implicitly. Break on auto_zone_thread_registration_error() to debug.

libpng warning: zero length keyword
libpng warning: Empty language field in iTXt chunk

And the Maxwell Console Output:

Hi Calix,

I'm going to take a look and contact you if I would need a test scene to reproduce the issue.

Cheers,
Peter

Thanks Peter!

The latest v3.0.0.2 release contains the fix of the volumetric issue.

beautiful
how long you need to make smoke like that? and what is the configuration of your PC

Hi seghier,

it was only a 5 minute test in Houdini. Rendered it on a 24-Core Mac Pro but don't remember the render time anymore. Maybe a few minutes.

Cheers
