your collision mesh is under the visable one for some reason. Try deleting the collision mesh and then copying the visable one again. IDK why it's like that.
This should help you out: The image above is how I fix this problem. You have to delete the colmesh-1 mesh, and apply the origin change to your original model. Once you've done that, duplicate your model and rename the duplicate to colmesh-1. Before you import this model into your map, you need to first make sure the old model is deleted from the map, and you've deleted the "cached.dts" file of your model from the folder. If you don't do that, you won't get the import options to center your ramp.
I fallowed the tutorial but for some reason when I load it into the game I get this: This is what my blender file looks like: I have included the .dae if that is needed
Call your LOD mesh "Cube_a400" or something like that, not 001. Changing that fixed the file for me. LOD meshes get triggered by the space (in pixel) they take in the rendered view, you define the size until which a mesh should be rendered with the number on the end of the name. If it becomes smaller than the defined number, the game switches to the next lower numbered mesh. A material should be created upon importing, not sure tho.
YES! Thank you! Been having this problem when I try creating anything more complex than a single shape. Also learned to re-center it every time I adjust it after that too. Now I can continue making my map with a customized elevated highway.
So I created this bowl object to drive around in. I followed every step you said, and yet when I export it, put it in the correct levels file, and put it in the game, it shows up invisible. I still get collision but I can't see anything. Any tips? Here's the blender screen right before exporting it.
