System Information
Operating system: Windows 10
Graphics card: NVIDIA GeForce GTX 1070

Blender Version
Broken: version: 2.80 (sub 35), branch: blender2.8, commit date: 2018-12-04 15:40, hash: be91d4ef95, type: Release
build date: 04/12/2018, 07:50

Short description of error
After closing and opening my blend file, all my texture painted textures reverted to black, and i can't paint on any of those textures when i go to texture paint mode. The texture paint tool does nothing when i try to paint. Furthermore, I can't paint on any new meshes/textures either.

I am using "automatically pack external data into .blend file". This might have something to do with it. I did not save my textures externally.

Exact steps for others to reproduce the error
Open the attached .blend file. You'll see that you can't paint on the house mesh.house.blend

While developers discover why images are not loaded again when opening .blend file to be shown in 3D View editor, if you want to continue working on your project you from Shader Editor you reload the image in Image Texture node from left dropdown menu, or make some modification in Material tab.
Also note that in the .blend file you have Strength=0 for the brush.

Oh haha, sorry I'm new to blender. You're right, I'm able to paint in the file after setting my brush strength properly.

Even after reloading, the texture is still black. It looks like the texture never gets saved.

I just tried saving the image externally through Image -> Save As, and the texture is now appearing correctly after a restart.

Blender 2.8 is still in an unstable beta state and it is not convenient for you to learn Texture Paint with it. You try to see tutorials on YouTube about texture paint with Blender from 2.78 to 2.79b. Texture paint in Blender always had usability problems by design:

It is better that you work in 2.79b to make sure that any problem you face is not due to a 2.8 bug.

Am I correct in assuming that the problem here is the same as in #45636 ?

Apparently yes, I mentioned the link of that report in message above.
The first problem is related to that report, user did not save images. It is not a bug, it is a design problem. The second problem is user problem (brush strength=0).
But I am surprised that no one here mentions the problem that when you open the .blend file, the texture is not refreshed correctly in viewport (it looks pink) until you make some change in material (Nodes or from Properties editor). Maybe a Linux problem only?

@YAFU I do not think that is a 2.8 problem. At least in 2.79, I've run into pink textures if the texture files were missing/not found.
I think it might be intended as this is what happens in some 3D engines when textures are missing (to make sure that the missing textures are obvious)

Yes, I know that pink color is the normal behavior when a texture is missing. But in this case texture is packed in .blend file. It's a refresh/viewport update problem when open de file. You only need to modify something in Material so that it correctly appears in viewport.
Edit:
Hmm, he's using Material slot. I'm not sure now, as I remember blender 2.79 in these cases open the file with the material Color, not pink.
Edit 2:
Here a simple file with packed texture:
text_paint_2.8.blend
It still opens pink by default and you have to make some change in material that viewport updates when opening file. I can be wrong, Texture Paint in Blender always confuses me a lot

I've also noticed the same problem in #58763 (textures are initially pink)

@Sergey @fclem I'm guessing that this is a problem where the packed textures are loaded before they are ready (and thus doesn't show up in the view port until something triggers a refresh).
I'm unsure who I should assign this to.

I think the pink texture problem issue was resolved, the other ones are not bugs.

Yesterday was working with blender 2.83 and texture disapeared partly (like loosing 2 hours on texture that i worked on 3 hours) , should have been packed in the project upon save. blender recovery didn return the picture either, knowing its experimental but without bug reports this will stay problematic (using blender several years).
I know alpha is a risk but i dont mind it, just reporting it.

@PGT2, best to report a new bug if you can reproduce it, with all requested information. There is not much we can do without more exact information.

Yep the bug is still here (Blender 2.83.0) and i didn't even close out the program... I literally just pressed ctrl z and all the textures i painted on turned black.

Just ran into the same problem as Kyle and Peter. Lost a good few hours of work even after diligent saving because Blender revereted the texture I was working on to a version that existed when I first opened the file. Incredibly frustrated.

I just lost 2 hours of texture painting just because i hit ctrl+z. all the textures are black. I hit save a good few times when i was drawing. I also tried auto-save. Still gone T-T
Im using 2.91

Hello everyone! I used Evee or whatever you call it to "shade" a diamond in blender. I saved it and then when I close it and reopened it, all the progress was there with "the blocks" but the diamond wasn't shaded. Could someone please tell me what is going on?

Now, when I opened a completely new blender file, it didn't let me even add the blocks.. I added an object of a diamond...

Thank you,
Paul101
