OK, another nooby problem, I didnt create seperate topic because I dont want to flood the forum with my questions
I've tried to give a texture to the model, from materials->textures, but I recieved only mess.How I can create .bmp texture files witch fit perfrectly to my model?How to import them in an8 file?Are they saved when I export the model into obj file?Should I use UV maping, what is this and what it means?
At first i would like to say that most answers can be found in the manual (link over the <----) or by search on the internet (google is your friend).
But on to your questions:
UV-mapping is a method to texture you models. It unwraps your model to a 2d image which is easier to apply textures to. UV-mapping is realy helpfull for texturing the more complex models. For UV-mapping you can use uvmapper, which is easy to use, or more advanced software like lithunwrap or roadkill (a bit harder to use, but better)
To texture a model you go materials and make a new one, you probably already know that. Load you .bmp texture file in the right slots (ambient, diffuse, specular, bump...). Then to texture your model, select your model and hit apply. Now with the UV-tool in anim8or you can move your texture around on the model. The UV-tools can be found in object and point-edit mode right underneath the selection tools (it's a button with UV on it). Or you can use one of the UV-map software i just mentioned
Textures are not saved when you export your model to an .obj, but i belief the UV-map is (.mtl?)(please correct me if i'm wrong).
