dealing with open geometry

Hello,

For some recent freelance work I have received geometry from modeling which will interact as a collider for some smoke simulations. The geometry (as often is the case it seems) isn't properly closed up in areas that are not rendered. I assume modeling thinks if something isn't being rendered the topology isn't important. It's difficult to set up sdf collisions for pyro because everything is open. Any advice for how to deal with this? Is there some alternative to pyro collisions that do not require sdf's, or do I just need to close everything up. I feel like I would spend more time fixing the geometry then doing the simulation : )

Thanks

Have you tried the Convex Decomposition SOP? It can close up holes, at the cost of sacrificing some of the original shape if you push too hard on Max Concavity.

1000 iq move, lol. I will give that a shot

This might help, in some cases. Divide SOP, Remove Shared Edges, and then Fuse with original.

At least Divide SOP might expose to you, where the holes are, and take care of them separately?
