Hey guys !

I'm building a procedural building tool which allows artists to create highly detailed parts of a building and these models are distributed to create any size structure imaginable.

I'm running into a bit of a performance issue, and not in the way i expected. The normals of the objects are wrong, this is usually fixed by using the facet SOP and “make unique points” and computing the normals. However, The performance hit I am taking is immense. The finished system went from real time functionality to a 3 second cook time between doing anything. Now perhaps this is unavoidable. But I was wondering if anyone has found a more efficient way of applying new normal information?

Maybe you can narrow down the operation where the normals are getting messed up and alter that? Or isolate what primitives have flipped normals and then use a reverse SOP to fix it that way?

Another idea is just try to do those operations as soon as possible.
