When i have a scene with a bunch of static scenery props like : I have a bunch of separate LOW POLY INVISIBLE collision meshes, some grouped and some for each piece ... These low poly invisible meshes are use for Camera Collision (mesh.checkCollision = true) and used as the 'Collision Mesh' in my BJS Toolkit for things like Physics Collision and Mesh Intertection... Is Working Great. Now when it comes to optimizing the scene .... i have a 'Static Batching' feature that will combine all the meshes on the 'Babyon Static' batching layer by material. Now at right before i cache each mesh for static combining i generate is collision mesh based of the 'Collider Component'... Ok... Say i end up with 250 separate low poly INVISIBLE pieces (so draw calls should not be AS MUCH of an issue) but the 'CHECK COLLISION' computation that has to go on for each mesh ... m.checkCollision = true. Would it be BETTER for the 'Check Collision Computation Performance" to keep EACH mesh collider separate OR combine all LOW - POLY mesh colliders into one big mesh... I don't know if the invisible collision mesh implementation would be the only case where it is better to have separate meshes (even though on same default material and even though they are actually invisible) than combine meshes... Purely based on if the the mesh.checkCollision would perform BETTER checking things on 250 separate low poly pieces OR using the same vertex count of all those 250 pieces combined into a single mesh... set with checkCollision = true; WHAT SHOULD I DO

Hi everyone! Is there any way in Babylon.js to combine multiple textures, or multiple materials on a single mesh? I know that it's possible to apply diffuseTexture and ambientTexture on a material at once, but if I have more than 2 textures? Like for example, it could be used for maps, having a satellite image as a base texture and then applying a layer with ambient pressure, and UV index, and wind direction, and whatnot
