CSGCombiner causing tearing CSG shapes

Hydroplane

Hey folks,

I was trying to combine a few CSG objects together with a CSGCombiner, and the final resulting shape seems to have a bunch of inverted, tearing textures with awkward or no collision. Does anyone know how to fix this?

None of the child CSG objects have inverted faces.

Example of what I'm talking about:

How it looks when running:

Now, when I un-child the CSG objects from the CSGCombiner node, they look like this which is how I want them to look:

How it looks when running:

Any help would be appreciated!

Try putting the ledge and the ramp into it's own combiner first?

That didn't seem to do it. The Ledge combiner is empty, I just made it to put the other CSG shapes in. When trying to combine the CSGBox1 and CSGBox2 in a separate combiner, it still glitches out.

While running:

Nevermind, I seemed to fix the problem by just deleting the two boxes that were having problems! I don't know why they were having problems to begin with, but it seemed like whenever I tried getting them to intersect, they'd glitch out and tear. It's fixed now though, for some reason.

I've experimented with csg booleans and one thing you can try is to increase the number of faces in shapes a bit.

I think what happens is the godot algorithm has a headache trying to tesselate over "big" faces except in very simple cases.

So give your 'diving board' a few more segments along its length and breadth
