Cull geometry by connected bounds June 23, 2023, 1:35 p.m.

Good day. I have a massively complex object with many thousands of parts modeled that are too small to render. I would like to check the bbox size of each connected set of prims and then delete below a certain bbox size threshold. I am not a coder, but know some python. I have a little (very little) experience with vex, although I am learning.

Can anyone suggest an approach to this problem? I have tried a foreach loop with python inside, tried a vex wrangle and a vex vop, but I don't know enough to get it to work.

Any help is greatly appreciated.


What is up with light "Exposure"? June 20, 2023, 4:07 p.m.

A lot of work these days does not use traditionally trained camera/lighting people. They will happily look at a monitor or grade and just make it work. Any digital artists unable to deal with an extra control called 'exposure' is not quite right for the industry these days.

Sounds light Ior is simply advocating his business model of traditional training... lol. Next he'l be deriding the Richter scale for not showing earthquakes in a linear form so people truely understand the power of nature.

Hey, thanks for the insult, but this totally misses the point. How about civil discourse and debate rather than cynical insults. Anyone properly trained in photography understands. Those whose only argument is personal attacks should probably step back.

Use instance ID in material? May 4, 2021, 1:12 p.m.

Good Day.

Can anyone suggest in LOPs how I might use an instance ID in a material. I'm trying to get material variation on each instance of a mesh.

Thank you for any ideas.
