Solaris RBD production workflow May 13, 2024, 8:49 p.m.

Yeah I had some back and forth with sidefx on this a while ago; when I first wrote up that method it was fast, then it got slow with later builds. The 'correct' answer is to swap over to the rbd destruction lop.

I've not used it on a project, but diving inside it just now, the hda seems designed to be tweaked and hacked. I'd assume if you have enough time and are confident in your skills, it shouldn't be too much effort to port an existing setup over.

Rob Pieke explains some of the thinking, why other methods are slow, why the new workflow is as it is here: []

i mean the other way probably works too, but usually with vex its better to think 'can i sample the points around me and then set a value on myself' vs 'can i sample the points around me and set their values'.

pccone maybe? i used that to art direct particles to check for collisions, move on paths. thinking out loud, you should be able to do that to just lookup in a specific direction and then ask 'should i be infected?' []
