Continued RnD of VFX/Games overlap and workflow.
Particle generated Quixel Megascans assets.
Each variant of the asset is attached to it’s own particle generator w diff seed.
Under 2000 polys from FBX. Particle Gen gives size and rotation variation. Hack way to create instancing in Flame.

Limited but could be helpful for visualization and BG assets.
