Redshift, and some minor compositing in COPS (houdini)

also did a recording of the entire process. Here's the sped up version:

Pretty happy how this one turned out. but i'm not 100% sure if I qualify because I only just now read that I'm not allowed to use any megascans assets, and I used some for the environment. The growing plants themselves are made by me though. So hopefully this still counts. Rendered in Redshift.

Ok aparantly you're also not allowed to composit in anything else than cops? Well ok I guess that disqualifies this as I comped it in Fusion. So I'll withdraw my entry for contest then, but I'll leave it here for funsies. But might I suggest removing the comp rule, because it doesn't make a lot of sense to not alow any other compositing package.

Motion blur with changing topology? April 27, 2020, 11:50 a.m.

Does anybody know how to get motion blur to work on something with changing topology (so from the velocity attribute) I cannot get it to work with any renderengine (tried karma and redshift)
I have it turned on on the rendergeometrysettings but I cannot get it to work even on a basic particle sim. Tried with cache sop, tried saving to .USD, nothing seems to work.

I'm probably just overlooking something but i've been trying since yesterday and I can't figure out why it's not working. Does anybody know what i'm doing wrong?
