Hi uNReaL1357,
As the users above have mentioned, having a good unwrap is key to getting a good texture. It can be a tedious process but it’s a necessary one. Also, this process carries over to lightmapping as well. You’ll need a good lightmap UV on your 2nd UV channel to get good shadows. Getting in these habits early can really help solidify your progress with 3d modeling and games! 
While I’ve not used Maya’s UV unwrapping it shouldn’t be too difficult to learn if you already know how to use Maya and have it at your disposal. I’ve always used 3Ds max. I Mahri726’s suggestion with RoadKill UV last night and found it to be easy enough to pick up as well. RoadKill UV Intro Video. The one benefit with this program that I saw in the 30-45 minutes playing around with it was that it auto-packs the uvs once you layout the seams. Packing the UV space was always the part that I dreaded doing even as much as I do love Tetris it’s not a game I always want to play.
I know I’ve mentioned it before along with other users on here.
A good model cannot save a bad texture, but a good texture can save a bad model.
If you need any further help keep posting and we’ll all jump in and give you some killer tips!
Thanks!
