Issues with Custom Table/AssetBundle Collision

[Tajidan]

Alright so googling i've noticed other people have/had the same issue like me but none of the answers i found could help me with understanding how to set up a complex MeshCollider in Unity that would not result in my asset falling through the world inside TTS.

I've read that Unity can't handle complex Colliders but those Posts are all 9years old. And i can't seem to find examples of similar complex Custommodels.

What am i doing wrong?

ignoring the posts from 9 years ago is what you are doing wrong

[Tajidan]

well, i'm not ignoring them as i clearly know that somethings wrong with my collider mesh. but tell me what? to be able to move minis around this table i simply cannot go with convex shapes unless i'm placing a hundred overlapping primitives as collider which seems just bad practice.

[Bone White]

it's not bad practice if it's the only practice that works.

[Tajidan]

Haha, well then... that's actually good news haha. I think i didn't want to believe it because i tried so very hard to make that collider to stay within the custom asset limitations, but with the asset bundle i guess i can throw those overboard? Thanks for opening my eyes XD i will update my progress.

#1 Are you sure your mesh is below 255 triangles after triangulation and modifiers?

#2 Concave colliders will only work with the object being locked. Behavior of concave colliders will vary in broken-ness when the object is not locked (static).

[Tajidan]

yes, 240 tris to be exact. if i import it as a custom model the collider still is convex, even after locking.
if i import it as asset bundle with the collider as a component of the prefab it will just fall through the table into nothingness.

do these limitations also count for assetbundles?
