Sprocket with 80 teeth using CSG2

Babylon.js Playground

I was helped with this about a year ago, on a different thread:

Rendering "simple" sprocket with 80 teeth

I am working on my final test to make sure BABYLON is a good fit for my application, and am running into difficulty with processing speed. I know CSG is SLOW. But I didn’t realize how slow until I tried the attached playground. Heads up, you will be waiting 5-10 minutes before it will render the sprocket. Any ideas what I can do to DRAMATICALLY speed this up? I need this to process within a few seconds, not minutes. I know this is probably not going to happen, but wanted to see if there…

I have tried changing this to use CSG2, but it’s not cutting out the teeth (subtracting). I’m not sure what the problem is. Any ideas?

I have tagged a new playground where I made the changes from the old one.

What helps me in this situation is to show the internediate meshes with some transparency.

You also have to make sure your shapes are manifold e.g. closed shapes. I played around with your playground but started getting “non-finite vertex” error. I suspect your shapes are not manifold? Summary: make sure your shapes are closed, manifold, and overlapping.
