Can i use intersecting meshes

HelionDark

Can i have meshes(white ones) crossing one another in Unreal ? Doing temple and im curious can i use one long beam instead of many and how will engine react?

I'm pretty sure it won't break or anything, but you might get some kinda nasty tearing at the intersection and the lighting won't be as good.

@Zablorg What kind of tearing are you talking about? This should be perfectly fine.

The only issue here I see might be lightmaps artifacts, other than that it should be perfectly fine. If not sure, just test it on small sample scene.

Depending on view distances and how you light your scene, intersecting geometry can help you plug light leaks. It'll cost you some (theoretical, frequently trivial) space in your lightmap and you'd get better shading if you use unique geometry, but it's usually a safe choice. Play around with using Lightmass AO maps in your materials to fake some boundary shading.
