Having trouble with textures

Whenever I apply my own textures to an object, the textures are extremely warped and you can’t even tell what it is. For example, I’m trying to make a chain-link fence, but the texture not only isn’t displaying correctly, but it’s not transparent in the correct places either. If anyone can help me out, that would be fantastic. I’m not asking for a texture handout, I just need a point in the right direction at the very least.

Thanks in advance.

Seems like you did not create UVs for your mesh.
UV mapping - Wikipedia

Those are necessary to map your texture to the model itself.

Also for transparenency you will need to use a shader which supports that - Transparent/Diffuse for example.

Ok, how do you make UVs? I have PhotoShop6, just FYI. Plus, I’m a total noob in the texturing and modeling department. I’m a programmer/scripter. So this is the part I’m having the most trouble with.

UV’s are made in 3d space (3d software).
It’s basically the library that translates between your 3d model and where it should lookup it’s material in the 2d picture.

Alright, well, I’m really struggling to make it work… and no offense Annihlator, but that didn’t exactly help. I have Maya and I looked up a lot of YouTube videos on how to apply UVs and I practiced along with the video, but I’m still getting the same result when I apply the textures I worked with in Maya. It works fine in Maya, but it’s just not cooperating with Unity.

Yeah sorry i know the reply isn’t the clearest description of how to make an UV. But i’d only know how to make a UV-layout within Cinema4D and wouldn’t plan on explaining how-to (it’d be a way too extensive subject).
UV-mapping is a hard technique to really make your own/master (in my opinion atleast :p) Did you make sure you saved the object after UV-mapping it and re-imported it into unity? Have you made sure that you’re exporting models with ONE uv-map?

I’m just going to create an invisible box around the area I want to close off. It’s getting way too complicated for me to focus on right now when there are other things I can take care of first.
