you can create your own - sort of - by writing to disk and then opening the written sequence with another app e.g. rv

Anyone know how to stop CHOPs calculating everytime something upstream changes? Even if I remove it from the stream it halts houdini whilst it calculates.

scratch that attributeOrient does do what I want

A basic question I have some groom attributes on my rest geo, I then scatter based on density and so I want the groom attributes on the newly scattered points. I then attribute interpolate these points across to my animated geo. How do I get the groom attributes to follow across correctly too? I know the attributeOrient SOP does some of the work but not all. Any help appreciated. cheers

If it's just falling snow then points do fine

I'm being a donut. Just setting input A P to input 2 P is doing what I want.......

Thanks Atom, That doesn't quite do what I want - the resulting geo does not match the deformed sim closely enough. This is because there's no useful frame to which I can freeze and make a rest. As I said - Match Toplogy SOP does what I want - it's just seriously slow once I start getting to the number of feathers I want to be matching. cheers

yeah

I've run it through a Carbon Plumage sim, which has changed the prim order.

I have two sets of geo - they have the same geo but the primnumbers have been changed in the second set. The Match Topology SOP does exactly what I want - which is to reorder the first inputs prims based on the second input, but it's very slow on a lot of data. Any clues as to how I can either a) speed it up or b ) build a quicker one? Tried using combinations of attribute copy/transfer and sort SOP but not to any success as yet. cheers

That didn't fix the problem - I've found restarting Houdini (or viewing in wireframe) to be the only way to deal with this at the moment

Nice one, thanks

Heya, Anyone had issues with the viewport display of the "Hair Generate" node? Thought I'd lost a load of work to find that it no longer displays unless viewing wireframe mode.

On the popadvectbyvolume dop change "Advection Type" from Update Velocity to Update Force. This will give you a different advection but it will not be constrained to the bounding.

OK - I've got it thanks. import hou sel = hou.selectedNodes() for s in sel: group = s.parmTemplateGroup() folder = hou.FolderParmTemplate("folder", "myFolder") folder.addParmTemplate(hou.ToggleParmTemplate("vm_volumenormal", "Compute Normals for Volumes", 1)) group.append(folder) s.setParmTemplateGroup(group)
