Sorry if this looks like a wip now,
I've tried the rop games baker and it seems like the graal i was looking for,
still investigating …

Hello all !

I have a project where i scatter a lot of trees and vegetations on a large heightfield map.
Each asset has 3 level of LODs with polyreduce and textures reduced in their mats.
All of those are instanced using redshift point cloud.


A given adult tree go from 14mo LOD0 to 510 ko LOD2 > fantastic !
.. those will be instanced a million+ times so pushing optimisation is key

i'd like to optimise more or try to push the limits :

1- For the last LOD : Is it more efficient to have a few hundred polys than just a plan with textures on it ?
Atlas VS Billboard i guess.

2 If so, then i'm wondering how to convert
a model + textures (where there is a few hundred polys),
to
2 textured plans at 180° angle.

I was wondering if like in camera projection we could extract a parallel view of a cam pointing at the object (tree),
extracting the textures then applying the “rendered” image to a plan of the same ratio as of the cam.
but i'm facing a problem with the lightning, as textures have to not being affected by light during this process.

May be there is a workflow for this i've missed in the SideFx Labs ?

Thanks a lot !

Thanks a lot AslakKs !
