Description

System Information
Intel Core 2 Quad, 8 Gb RAM, NVidia GeForce GTX 960 2GB
Windows 7 x64

Blender Version
Broken: 2.80 up to e3c586e262dd from 2019-07-12
Worked: 2.79

Short description of error
Subdivided Multires modifier stops showing textures when you enter Sculpt Mode.

Exact steps for others to reproduce the error

  1. Open Blender, add some base color texture to the default Cube's shader.
  2. Add Multires modifier, press Subdivide
  3. Enter Sculpt Mode
  • In 2.79 it is still possible to see your textures and masks and everything works as expected.
  • In 2.80 all your textures and masks becomes disabled which makes it extremely hard to work.

I have noticed that when I change the texture my object changes its color so it looks like Multires in 2.8 loses UVs during the Sculpt Mode for some reason. This becomes a very big problem when you have to work on landscapes.

I fear that it is working as intended.
But can you send a simple .blend file showing the issue?
So we can work on a solution.

If i want to add a color on my sculpt for a better view i do it in the viewport display. Like this ->

That issue is 100% reproducible with a default Cube and a generated checker texture but if you need an exact file then here it is. I forgot to mention that you have to either switch to Texture mode in Workbench or switch to any other mode that show textures by default. In my example both objects have the same material, texture and uv but right object is in Object mode and left object is in Sculpt mode. You can open my file and switch from Sculpt to Object mode and texture will come back. The same exact setup works perfectly fine in 2.79 and you will be able to see texture on both objects both in Sculpt and Object modes. This is a serious regression because it makes it extremely hard to work with landscapes and other environments where you need to see a texture while sculpting.
I have tested that issue both on NVidia and AMD GPUs on several different computers and the problem is exactly the same.

Just in case, this is exactly the same setup in 2.79 with Cycles, Multires and Sculpt mode on the left object. I have noticed that there is no "Subdivide UVs" option in 2.8 so I still think there is something with missing UVs
