Something odd happened this evening… I had been using the channel editor repeatedly. Then suddenly, opening the graph editor hung houdini. Now it happens even if i open a fresh file with only one geometry node with one keyframe.
Check out the attached image. When the channel editor opens, this is what I see. Be sure so check out the value in the lower left hand corner. That value is consistent with each hang.
Is there something I can clear, a preference file to delete, or some textport wizardry I can use to “reset” the graph editor?

I double-checked… that particle nebula was on the order of 250,000 particles (not 10k). I was still iterating, but my memory was way off.

We have similar system for genereting such pointclouds with Maya, codenamed “Scallop”, but we have plans to reimplement it for Houdini as OpenSource project. Keep in touch.
Do you have an rendered examples?

Thanks for posting your interactive flame-thing. It was a help.
Here's my first attempt:

Using Houdini, has anyone tried their hand at the Doc Baily nebula effect he used in Solaris, etc?

Thank you. The AttributePromote example almost does what I'm after… I was able to accomplish what I wanted, but I wonder how you would do this…
Each shattered piece is made up of multiple primitives forming a primitive group. While I was initially able to get the minimum $CR value for each primitive and copy it to the other points of that primitive, I still had different colors per primitive in the overall primitive group.
I got around this with an add SOP. By deleting all of the primitives in a group, keeping the points, and then creating a single, new primitive (0-$N), I was then able to sample for the minimum value. I then copied this $CR back onto the original primitive group in a point SOP.
Is there a better/different way?

I have shattered geometry broken up into n primitive groups. With a point SOP, I color the points with $BBX in the diffr field. This gives me a black to red (0-1) ramp across all of the points.
Now, for each primitive, I want to determine the lowest value of $CR for that piece and set all points to be that same value.
So if “piece3” has $CR values of .2, .23, and .256, I want to set all points to have the same diffr of .2, and so on for each piece.
Someone smarter than me showed me how to do this once, and I'm trying to replicate it (to no avail).
