when trying to move into a pipe which is clearly open and also on the sides of the mesh which aren’t enclosed like the pipe.
This is what happens when the collision fidelity is set to default, in hull and box mode the collision is treated as one large block. Does anyone have any solution to overcome this problem? Ideally this would be a slide.
To better understand how Roblox handles collisions with meshparts and unions, turn on ShowDecompositionGeometry in file -> Settings -> Physics. Generally you will not get good collision fidelity in large or highly detailed shapes.
To add onto that, IIRC, the collision detail is measured as a percentage of a CSG/Meshpart’s complexity, meaning that the more complex a shape is, the less “focus” is applied to collisions and is instead spread across the whole shape.
So even splitting a mesh at a random spot (not necessarly at a concave area) for smaller, less complex chunks will allow ACD to focus on fewer triangles and create better collisions.
You should support (like and reply with new use cases) the feature request in the feature request category then, engineers won’t be going through support threads for requests when we have a dedicated category.
