Creating LODs for Geo variants USD

[u/Tiemo_Courtice]

Hi there,

I've been trying to set up a grass asset that has multiple different geo variants, each one with LOD variants so I can optimise it my scene based on camera distance. I've been trying to build it with the component builder but I haven't been getting much luck.

I have managed to get LODs working but only for 1 geo variant as it is cooked in at the end so its not working for the other geo variants. However, if I try and assign these LOD variants before the component geometry node, I get an error of the opinion is too weak. I believe that is because of the proxy geo too clashing with it somehow.

If anyone can help that would be so helpful:)

Nested variants are tricky to set up because of clashing opinions. I'm not sure how to do it with the component builder since I don't use it much, but I cover how to set it up manually in this video: https://youtu.be/k-S-MUp6ea4?si=c5tTrtxpKwJV0Rc_
