System Information
Operating system: Linux Mint 19.2
Graphics card: GTX 1660

Blender Version
Broken: 3.0
Broken: 2.92
Broken: 2.80
Worked: 2.79

When {key F12} rendering from editmode, multires modifier is ignored.

Exact steps for others to reproduce the error

throne upload.blend

Open file
you should be in editmode
{key F12} render, notice the multires modifier is not in effect
go to objectmode
{key F12} render again, notice the multires modifier is now in effect

Expected behavior: multires should be applied in {key F12} renders no matter what mode you are in

Original report:

I've included a file{F10150774} which demonstrates the problem, in Eevee or Cycles (on GPU and CPU). I removed all other materials and meshes (the file size was initially around 200 MB+, which isn't helping here); but you may need to add a light to see it more clearly. Rendering with the viewport in object mode provides the displacements (there are two of them); rendering from edit mode removes those displacements. (This could in theory ruin an animation if someone's unaware!)

By the Unix philosophy, the 3D viewport and the render are two entirely separate tasks, aren't they? I don't think they should affect one another in a stateful way.

Current workaround is to consistently render from object mode. I have no idea what other viewport modes might do to the render, but it's worth looking into.

This is due to multires [which is not applied when in editmode].
The displacement actually seems to be applied.

This was working fine in 2.79, not sure what changed in 2.80 in that regards.

#67026 (Cycles does not render geo with Multires modifier while in Sculpt mode) might be related, will confirm for now.

Philipp Oeser changed title from ~~Rendering from edit mode removes displacement modifiers from actual render image~~ to F12 Rendering from edit mode makes multires ineffective

Thank you, I didn't think to check on Multires.
