How to generate correct mesh in Unity Blender?
Make sure you have a Mesh Collider component on your object with the correct mesh set. Watch out for the convex parameter for flat objects, as it can sometimes fail and give you a box collider instead. I just noticed you said you were using a RigidBody, which means you need to have Convex set.
Why does ceiling appear as one mesh in Blender?
Click to expand… This is exactly the problem – in blender the ceiling appears as a single mesh, but when I import it into UNITY it appears as one mesh with 3 “submeshes”. (see the image last post) I don’t know why, or even what “submeshes” are, other than they each can use another material]
Can You import a blender model into unity?
I’m importing a model from blender into unity, (which I export from blender as an fbx first, as I like to keep the modelling separate from unity whilst I’m experimenting) which consists of 3 meshes, each with different materials, and therefore different objects in blender (the floor, the pillars and the ceiling).
Why do I need convex mesh in Blender?
I just noticed you said you were using a RigidBody, which means you need to have Convex set. A solution to this is to make a second mesh in Blender with a third dimension to it, then set the flat one on the Mesh Filter and the one with thickness to the Mesh Collider.
What kind of bounding box does unity use?
Unity first uses Axis-Alligned Bounding Boxes (AABB) to check which colliders actually have a chance to collide. Checking two AABB’s for intersection is a very cheap operation.
How is a mesh Collider ” performance expensive “?
A Mesh Collider will have to figure out the collisions for every single face of the whole mesh, Therefore It would take Longer (No significant difference most of the time) and would consume more Hardware Resources which would also slow down the performance. Q -) Do they reduce performance simply by existing or Colliding ?
