Description

Some of my original PSD layers have strange invisible dirt which causes its dimensions to be incorrect. For example, see below: This causes the mirror axes to be displaced and effectively unusable.

Suggested solution

Some sort of basic texture editor for cleaning weird "dirt" (especially for spotting stray transparent pixels) so that the node dimensions can be recalculated.

Alternative solution

1. Add a feature where the user can select which region of the textures should be taken into account and exclude everything outside the region.
2. Allow moving the origin of mirror axes.

I'm not sure if it's a good idea to solve this problem in the creator,

since the layer may be updated, Maybe this problem can be solved in drawing software

and how to automatically select pixels to identify details or dirt is also a problem.

Two users from Bilibili mentioned about how "interworking" with Photoshop is a life saver for riggers. So I guess the whole picture is this:

• Yes, it is true that no graphics editing functionality should be built into Creator. Users should pick drawing software of their choosing.
• But, it is good to shorten the path between a graphics edit to the edit being reflected on the model as much as possible. Could be a Photoshop plugin, could be a special mode where Creator poll the constantly updated graphics source file, etc.
