Help How to build a goal net mesh to use with Obi?

[josemendez]

Ok but how shoud I compose the model? Maybe with 4 separated planes (one each side, one top and one back)?

This model is all connected, like a rectangle with 2 faces deleted. I read the definition of manifold and assumed that this model wouldn't work, but my doubt is how should I build the goal net to be functional with Obi.

If I build it with 4 planes, I imagine there would be issues regarding collisions in the edges for example..

The model is fine as-is in that regard. You can take a cube/prism, delete two faces, and it’s still 2-manifold, as it can be “unwrapped” onto a flat surface.

As long as the surface is orientable and there are no obvious non-manifold structures (isolated vertices, zero length edges, zero area faces, edges shared by more than two faces) it will work, so most meshes pose no problem.
