Short description of error
UV Editor in 2.79 had a feature to display uv with all modifiers applied. This feature is not available in 2.80, but from what I can see checkbox is back in 2.81 develop builds. However currently it seems to not work. Might be it's still development in progress? Although in that case - I think checkbox would not be visible.
What is visible in the uv editor:
What is visible after applying mirror modifier (this is expected result without the need to apply modifier):
How it looked in 2.79:
Exact steps for others to reproduce the error
- open provided file
- It contains cube with mirror modifier. All is default except of checked "Flip U" and "Flip V" in "textures" section.
- In the uv editor sidebar is visible and "modified" checkbox is already selected.
- This means that uv editor should display wire-frame with modifiers applied, yet it's displaying wire-frame of single cube only, not showing mirrored one created by mirror modifier.
