(I don't have any access to external programs, nor the patience or time to learn them. I want my Blender problems to stay in Blender.)

I have a Picture inside my UV Editor, and I wanted to know a way to apply a material, color, or paint to affect this image, or my mesh.

'This picture wraps around my barrel. I have cracks in the wood itself, and separating the individual planks. I want to apply 'black' to those cracks.'

I wish I could provide visuals, but apparently the 'Blender Forums' doesn't allow 2 images.

  • $\begingroup$ Yes, images would help us understand what you need. You can upload them to any image hosting site and then edit your question to add the link. Also, stricltly speaking, this is not a forum, but a question and answer site please take a minute to read the help center section to familiarize yourself with the site. $\endgroup$ – user1853 Jun 29 '16 at 13:40

To paint on a mesh in Texture Paint Mode you need a UV unwrapped mesh.

Then, there are a couple of options:

  • Paint on a texture using the UV editor.

    Enable Paint Mode and press T to bring up tools for painting

    The image below shows where you toggle paint mode on

    enter image description here

    Choose the tool you want to use, and paint directly on the image.

(Please see this link for more info)

  • Paint using the 3D viewport.

    Enable paint mode, select your tool and paint directly over the mesh.

    enter image description here

IMPORTANT: After you've painted on the texture you need to save the image on the UV/Image Editor. Use Save Image on the menu or AltS to overwrite the original image with the changes or use F3 to save as a different file)

enter image description here

If you don't save the image and close blender, all of your painted texures will disappear forever

  • $\begingroup$ It's also worth noting that it's also possible to texture paint directly on the textured mesh on the 3d view , since OP mentioned this. $\endgroup$ – user2816 Jun 29 '16 at 6:09

  • $\begingroup$ I saw your previous comment Ari. Yeah, that was a dick move by his part. But unfortunately I can't do anything about that. Thanks for the help. $\endgroup$ – JaredWolf Jun 29 '16 at 22:41
