Hello. I am a new Houdini starter. Nowadays, I am focused on Procedural building generator for UE4. Acutally, I already made a node tree for a medieval building, and make it as HDA. And then, I tried to make a village. So, I copied HDAs in UE4 and made 200 variation buildings.
My question is about optimization of drawcall in UE4.
In one HDA, instance meshes are applied, but is there a way to apply instance meshes together in different HDA? When creating a village, is it the right way to copy HDA individually?
I wonder whether each HDA files are available to share meshes that use same mesh in each HDA or not.

Hello, very interesting, please post more of it.
Anyway, regarding your question you might found someone that can answer you here
