To create a texture for a mesh, I suggest using this tutorial to learn the basics:

https://en.wikibooks.org/wiki/Blender_3D:_Noob_to_Pro/UV_Map_Basics

You can also save the uv map and edit it externally after exporting it with the mesh unwrapped. From there you can reimport it to use it on your model.

However, this I don't think is the right discussion board. Try using the sfm subreddit for general questions as this isnt really related to the tools.

well thanks anyway and yes i did found a way to texturize the color that i done

:)

thanks dude for helping out
