RBD: Replace proxy with hi-poly geo at rendertime?

[ajz]

Hello.

I'm making an RBD simulation that involves several hundred point objects. For performance reasons I'm simulating several types of low-res objects but I'd like to replace them with their high-poly versions at render time. I looked up the docs, but cannot find any info there on how to do it. Could someone perhaps give me a hint?

I've been doing some digging and I found this great example by Tamte: https://www.sidefx.com/index.php?option=com_forum&Itemid=172&page=viewtopic&p=132232#132232.

With a subtle modification it works with point objects.

 

Here's the scene, in case someone is interested:

I just noticed that there's a slight misinformation in a comment of the point_source_torus node, because I forgot to re-enable render as subdivision. But it's irrelevant for the whole process.

Indeed. That´s one of the simplest ways.

If for any reason instead of one single object, you have several with different positions (for instance a voronoi-cutted object with different pieces and rotations) you should use the Transform Pieces SOP, which works great.

Thanks Netvudu for the tip about Transform Pieces SOP. I'll most definitely look into it.

Until then, I took advantage of Anim's example (http://forums.odforce.net/topic/16949-creating-random-rbds-with-rbd-point-object/#entry103315) as a base for setting up object randomization.
