It would be very helpful to have grid and pixel snapping in the UV editor. Also, being able to quickly snap the 2d cursor to a vertex and then rotate from the 2d cursors pivot point would be great. We can currently snap the 2d locator to vertices by using shift+S and use "cursor to selected", but being able to snap to vertices directly could speed up the process when creating modular assets for environments.

Proposal updated 2022-09-10 after discussion with Campbell in the comments below

UI

Change the current grid options in the uv overlay menu into an enum of 3x items [ Dynamic | Fixed | Pixel ] where dynamic is the current default "Fixed" for "Fixed Subdivisions" checkbox and "Pixel" would be a new option to align the grid to pixels. "Fixed Subdivisions" could have an X/Y setting instead of a single value.

See more info about dynamic grid here
#78389

Grid overlay on top of images

Optionally show the grid on top of the image as an overlay option since it's not possible to see the grid with an image at the moment.

Rename snap to pixels

Rename "Snap to Pixels" to "Rounds to Pixels" (or another names that avoids the term "Snap") this is a post-process when transforming, it's not applied as part of the snapping.

Desired behaviour - starting point (part 1)
Green arrow shows intended mouse movement and snap target when using “snap to dynamic grid”.

Desired behaviour - final snap result (part 2)
Green dot shows snap point for where dynamic grid and closest vertex meet up when using “snap to dynamic grid”.

Hi. I'd love it if you guys check out my small proposals about UV editor UI, both garnered some attention on rightclickselect

I'm showing this in this thread, for anyone looking for the option that already exists elsewhere in the menus.

It's only pixel snapping that is currently missing from this task

This is related to the gsoc task

Re-reading this task it's not so clear how this should be handled exactly.

As @CornetTheory points out, there is already a pixel snapping option, how would this fit with the proposed new pixel snapping option.
The dynamic grid part of this proposal now seems unnecessary? (it's now possible to configure the grid).

This is made additionally confusing by pixel-snapping in the menu not actually being a snapping, it's more of a post-process that quantizes UV locations to pixels.

Suggestion:

Rename "Snap to Pixels" to "Rounds to Pixels" (or another names that avoids the term "Snap") this is a post-process when transforming, it's not applied as part of the snapping.
Add the option for the grid to match the pixels.

This could change the "Fixed Subdivisions" checkbox into an enum of 3x items `[ Dynamic | Fixed | Pixel ]` where dynamic is the current default "Fixed" for "Fixed Subdivisions" checkbox and "Pixel" would be a new option to align the grid to pixels.

When looking into this I noticed two possible additions that don't have to be part of this proposal.

Optionally show the grid on top of the image as an overlay option since it's not possible to see the grid with an image at the moment.
"Fixed Subdivisions" could have an X/Y setting instead of a single value.

Interesting! I have totally missed the existing menu item Uv > snap to pixels, since it was placed in the menu and not in the snap settings.

Yes, I agree.

Your suggestions sounds great to me.

These bonus additions sounds great to me.

@DanielBystedt would you mind updating the proposal at some point? It's changed enough from the original that anyone reading it needs to dig into the replies.

It's unfortunate that it doesn't make sense to locate this in the snap popover (since it's not tied to snapping).

Perhaps there could be a single-icon drop-down next to snapping so this isn't so hidden, although the header is already quite full.

Hi @ideasman42!

I have updated the task based on your suggestions and moved this task to "Approved design tasks" in the workboard.

Sorry for the late reply. I must have missed your latest comment in May.

As there's been quite a bit of change in this area, (as discussed offline), we're going to 'Resolve' this task with regards to the visual appearance and some snapping progress. When there's further improvements to the snapping requested, we'll open a new task based on the current working behavior.
