See https://vimeo.com/285813013 [vimeo.com] the end of this video covers converting the point cloud to a texture, your technique is correct and should work. Worth checking for errors in your uv setup, the pchannel setting on the pcopen.

I’ve not looked at your file but the default buoyancy value on the solver changed a few versions ago. Try increasing the buoyancy value, also make sure that your smoke has a default temperature of 1 or greater - that’s set in the smoke source network, not the sop network.

Hi

The tutorial on Dops keyframes was made before RBD packed objects existed. In general the easiest way to manipulate packed objects is to use a SOP solver. Inside the solver the packed objects will look like a set of points with attributes on them, one point per object. For example setting the active attribute on a particular point will determine if that object is simulated, changing the position (P attribute) will move it. The RBD packed object helpcard has some details of the attributes.

I did a tutorial on the sop solver some time ago. It is still valid with a minor modification on how you wire in the solver if I remember right. I believe the project file was updated to work in more recent versions of Houdini and is commented.
