Nagivation doesnt work with static meshes

[YerkoAndrei]

Release Type: Official Release

Version: 4.2.0.2149

Platform(s): Windows

Describe the bug Nagivation mesh ignore all static meshes

To Reproduce Steps to reproduce the behavior:

1. Create new project
2. Add simple navigation configuration as in the official tutorial
3. Add a plane and some cube
4. Add static colliders for both
5. Add infinite mesh to plane
6. On collider shapes of the cube, add static mesh and reference itself

Expected behavior Navigation mesh should update and use the cube as a wall or obstacle

Screenshots With static mesh

With cube shape (how it should look)

Additional context

• Its not a visual problem, characters navigation doesnt work
• Using a convex hull works good, but it cant be used as a workaround
• Creating a collider shape asset doesnt work
• I tried on master and it doesnt work either

If you enlarge the box does the mesh still work with the surface of the mesh? Im curious because I know I used a static mesh at one point for terrain on the old recast nav mesh and it worked for that at least.

Nope, i cant make it work, i have tried with fbx and glb, so its not that.

Im looking the code and the ColliderShape of the StaticCollider is alway null when using a StaticMesh. I think thats the problem. When the PhysicsComponent try to ComposeShape, it call CreateShape with a null service, wich is only used by Asset and StaticMesh (just these 2 fails). I dont undestand yet what is an EntityManager and why is null, so if someone know someting related please help.

I should be able to look into this a bit this week. The file type should not matter so long as the collider is created, it uses the information from Bullet to create the nav mesh.

Can you also try to downgrade your project to 4.2.0.2122? Im wondering if one of the PRs may have had a larger affect than intended. https://github.com/stride3d/stride/pull/2262
