Is there a way to save the texture of a mesh that was painted with the texture painter externally? I'm trying to create a mountain for use in a game and, admittedly, my texturing skills are garbage unless I can just paint on the model (I'm more of a programmer). I have a mountain with acceptable textures in Blender, but I need to save the painted texture externally for use in Unity. Google hasn't turned up anything useful.
Open the texture in the UV image editor. If you have multiple textures beside the one you want to save, click the little PNG icon and select the proper image.
To save the image, click Image*> Save As Image. You can also hit F3 while viewing the image.
You will be asked to give a file location.
