Symmetrise UV map/unwrapping in 2.8

I am UV unwrapping a symetrical model and i want the UV layout to also be symmetrical.

I would like to unwrap and position half of my UVs on half of the texture and then mirror all the work onto the other side. Then i can nit the UVs together down the center line.

In blender 2.8 is there a way to easily symmetrise the UV layout?

I know i can copy across the seems but im unsure about mirroring UVs.

I want to be able to paint onto the model symmetrically at least until details are going to be added.

thank you

have you tried this?

On the mirror modifier, there are this params, flip U and flip V

It will also mirror the UVs.
When checked, there is also the Flip Offset params which appears
It allows you to set an offset on flipping the UV
(NB : Note that it would appear in UV editor only when Modifier is Applied)

See you :slight_smile: ++

For the other half of this, getting UV coords appropriate for mirroring:

Try roughly organizing your UV map (center roughly at mirror line, no overlap at mirror), setting cursor position to your mirror line (0.5?), scaling all center lines to 0 in x (or whatever) about cursor, pinning those verts, then re-unwrapping. At an early stage in your creation of UV coords.

I have messed around with that function but its not giving me what i need. not sure if I’m using it incorrectly. might need to look into how it works a bit more.

it flips the UVs to mirror but via the x co-ordinate rather than an exact UV symmetry of the layout.

though must admit i hadnt seen that tool so thanks for pointing it out to me, im sure i can make use of it.

Actually scrub my last answer, i played with it for a bit and got it to work.
it was being messed up by sync selection.

thank you
