I need to poly-reduce some assets and the poly-reduce sop works very well in most situations, but here is a situation that causes me a lot headaches :
Sometimes, my high-resolution meshes ends up with little holes/missing polygons in them like this:
…it doesn't really matter for us when we render the high-res mesh since we never see these holes. They are occluded and super small.
But when we poly-reduce this mesh, these small holes become big holes like this:
…which now becomes a big problem.
How can I make sure my poly-reduce operation ignores small holes like this and treats the surface like a fully closed surface?
I though of using a polycap, but that closes the bottom surface as well and creates a weird shape in the end. I don't want that bottom to be capped, but I do need these small holes to be closed so my poly-reduce gives me clean results.
In this particular case, I could go and close those holes up by hand, but I have thousands of meshes to process, some with thousands of these small holes. So I'm looking for an automatic process that can close these small holes so that my poly-reduce operations can give me clean results.
Any suggestions?
