Sorry if this is a bit novice but I am far more into engineering than game development but I just want to make a small 3D game for fun with XNA (well actually MonoGame). The thing is that I don't have any 3D modeling software nor do I really have any experience with them. I do though have and know my way around CAD software. I am using a very light weight package though and the only modeling type format it can export to is .obj. Now what I need is some way of creating a texture for this model (my CAD software does not support this) as well as a way to get the model with the texture map converted into either .x or .fbx that I can use for XNA. I have searched a lot but could not really find an active link for any converters and I could especially not find info on managing textures.
PS. I tried something like this a long time ago in Game Maker and then to do textures I remember using some sort of tool that put all the outlines of my model into a bitmap file and then I could just draw inside them. I am hoping for something like this here.
