Hello,


I've done the “intro to POPs tutorial -CatherineWheel”. When I render my scene I see only little gray spheres representing the particles.
How can I render my particles so I can see colored points or strikes ( eventually motion blurred) ?

In the tutorial they colored the particles with a Color POP, but why if they don't render in this color (of the ramp)?

Thanks,

bernard

Hi,

What you might need to do is that in your SOP network, append a Attribute SOP after your popnet and rename Cd to diff in your Point attribute. Mantra can pick up the diff attribute because the default shader is built to pick up ‘diff’ instead of ‘Cd’. If you have a Copy SOP in the chain, you may have to turn on the “Copy Template Point Attribute” in your Attribute tab.

Basically, if you write a shader to pick up any attribute name, Houdini should be able to pass the attribute of proper type into the shader.

Hope this helped,
Alex
