I am attempting to add some textures to a model I am rendering using OpenGL. Here is what the model should look like:




Right now I am just attempting to apply a single texture to the door. It looks like there's something wrong with my texture coordinates, but I am not entirely sure.



Any suggestions?

Hello there,
it seems that you are either using flat planar mapping on the top/down axis or not having UV coordinates assigned to each and every face of the model, specifically the part on the sides where the texture seems ´stretched´

Check:
- Do you have per vertex UV coordinates in the file?
- Are the UVs exported correctly and assigned to their respective vertices?

A good idea would be to check your code with an existing model from the web.
Greetings!
