Need help:Custom Textures

I made a model and I to add a custom texture (either in blender or transferring it to another app and customizing it there). By custom texture, I mean I can draw on the model itself, and not import pictures since my model has so many faces and needs different textures in different places. If anyone has any ideas please help :slight_smile:

You can paint directly onto your model with the texture paint tools
