Problems getting static objects to work.

[WALP]

Rather confusing and unprecise to be honest.
you dont even mention what software the model was created in. Also what do you mean you saved the texture as a MAT. file? you did not just change the extension did you?.

Well when exporting make sure the texture is applied to your model inside the software you export from. because the collada file itself is what points to the texture, and the texture is also what points to the mat file. A mat file (and a mesh) should also be created automatically when you open your model in the model viewer if it was exported proberly that is.

Also make sure that your texture is stored in the right place when you export, otherwise you will have to open the collada with fx notepad++, and change the adress of the picture manually.
