danw Posted March 1, 2013 Share Posted March 1, 2013 I've got this annoying pipelining issue - I have particles exported out from another program as bgeo sequences, with all the correct point attributes set, and I'd like to just use a delayed-load-procedural to bring them straight in at render time. The only problem is, the bgeos only contain points, they're not particle objects. I know this is as simple as loading them in and using an Add SOP with "Add Particle System", but I don't want to have to load and recache them just for this. Ordinarily I would just flick on "Render As Points" on the object, but I want them to render as sphere-primitive particles, not point-primitives. Any way I can get around this? Is there a way of flagging an object to "Render As Point-Spheres"? Is there some clever point-attribute I could set to override the point-primitive type? Any cunning way to "Add Particle System" at render time? Quote Link to comment Share on other sites More sharing options...
Annon Posted March 2, 2013 Share Posted March 2, 2013 Simply add an "add sop", go to the last tab and add particle system. Quote Link to comment Share on other sites More sharing options...
danw Posted March 2, 2013 Author Share Posted March 2, 2013 Yup, that's what I said :-P Any way I can defer that to render time with a Delayed Load Procedural? Or is my only option loading the file into Houdini and editing it directly? Quote Link to comment Share on other sites More sharing options...
Annon Posted March 2, 2013 Share Posted March 2, 2013 My bad, sorry I didn't read it all. I haven't done delayed load with particles, I'll check it when I get in front of my computer if no-one else steps in before hand. Quote Link to comment Share on other sites More sharing options...
danw Posted March 2, 2013 Author Share Posted March 2, 2013 Hehe, no worries. I get the feeling there's no solution... it's in the same boat as defining/overriding the pscale attribute at render time. I would be enormously elated to be shown how to do either of those things... they'd save me cumulative aeons of heavy network/disk-bound reads and writes over time :-P Quote Link to comment Share on other sites More sharing options...
Annon Posted March 2, 2013 Share Posted March 2, 2013 You know about unloading right? If not, hit T in the network view. You can unload everything from memory. 1 Quote Link to comment Share on other sites More sharing options...

danw Posted March 4, 2013 Author Share Posted March 4, 2013 Woo, thanks SYmek, that sounds pretty intriguing. Alas, looks like I'll have to get my hands dirty and delve into the dark world of plugin-compiling... I really should try and make the move to Linux, I probably wouldn't be nearly as irrationally scared of it then. Quote Link to comment Share on other sites More sharing options...
