EEVEE UV not available until you go in and out of edit mode
Closed, ResolvedPublic


Blender Version
Broken: rB6a0d7f9e4126
Worked: ?

Short description of error
On file load, the UV is not displaying correctly until I go in the edit mode.

Exact steps for others to reproduce the error
Open file (simple primitive with UV and a EEVEE material that uses the UV):

  • Switch to Rendered Mode.
  • You don't see the UV.
  • Now go in edit mode, UV is there.
  • If you go to object mode, UV is there as well.

Event Timeline

Dalai Felinto (dfelinto) moved this task from Backlog to General Bugs on the BF Blender: 2.8 board.
Dalai Felinto (dfelinto) triaged this task as Confirmed, Medium priority.

So basically it's because the batches are tagged as dirty when switching from workbench to eevee.

Adding BKE_mesh_batch_cache_dirty(object->data, BKE_MESH_BATCH_DIRTY_SHADING); at the right place should do the trick but I don't know where to put it.
Or maybe we should simply tag the whole scene to update in this case but I don't know how to do it either.

Note this is related to T51931. However see concerns about this approach on T55326.

@Sergey Sharybin (sergey) This is broken again. I can bisect if you want.

Appears to work in latest builds.
