I have SketchUp Pro and I’m trying to import a complicated model into Unity as a .fbx. The import is fine but when I play the game I fall thru the floor. I also notice that when I am above the floor it is invisible until I fall thru it. Any ideas? Thanks in advanced for your help!
Sketchup is notoriously bad. I’ve spoken to Unity about fixing this, they are open, so is Google. Sketchup draws both sides of each polygon, but exports only one-sided, and it’s random which sides are correct. I export as dae (or whatever), take into Blender to fix the normals, then just use the .blend file to go to Unity.
Mesh colliders are notorious for letting things fall through.
Make sure a mesh collider is attached to your model.
You can add another cube as for a floor collider too.
Regarding you only see the floor until you are beneath it, perhaps try flipping normals in Sketchup. Although I have no idea how to do this in it.
Try putting that fbx through another 3d program and export it. I had the exact same problem.
I had the exact same problem, try putting the fbx through cinema 4d and re-export it (or any other 3d program, i used c4d though) worked for me.
It there a file format that SketchUp Pro can export that fixes the normals?
I export from SketchUp to Unity without any problem. Here is my export settings:
If you want both sides of a face to be visible, be sure to select the “export two-sided faces” option in the option menu when exporting. Good Luck!
Make sure you don’t have gravity acceleration on that could be why you fall through the floor. I think Unity defaults to gravity movement for object assets.
hi.
i export with fbx from sketchup, i want to make it one mesh. how can i do it?
just put on GENERATE COLLIDER
