Transfer Editable Poly Edge Selection to UVW Modifier Edge Selection

[rartidiello]

Hi, It would be nice if there´s a way to transfer editablePoly Edge Selection to UVWModifier Edge Selection just the same way as polygon selections are transfered.

Are you talking about how you can select some polys, stay in Polygon Sub-Object mode, add an Unwrap UVW Modifier and the modifier only uses the selected faces?

If so, you can already accomplish this via this method: Select your Edges, then CTRL+Click the Polygon sub-object icon in the modifer tab > Selection Rollout (or simply right-click the view port and click Convert to Face in the quad menu). This will change the face selection to those needed for the action; then add an Unwrap UVW Modifier.

Please let me know if this works for you.

Thanks for your reply, but what I need is given a selection of edges at the Editable Poly level, to have the same edges selected at the Unwrap Modifier level.

I mean, I have a selection of edges in the Polygon Sub-Object mode and I need to select the exact same edges in the Unwrap UVW Modifier.

Thank you for clarifying. So what you mean is how, when applying the Unwrap UVW modifier, it defaults to Polygon Sub-Object mode with whatever polygons were selected in the editable poly are pre-selected? You would like the edges to default to being the same selection from the object when you switch to edge mode in the modifier?

[rartidiello]

Yes , I need specifically the edges.

For example: I have a number of selected edges in my mesh that I need to break in the UVW Unwrap Modifier and I can't just get that selection automatically in my UVW modifier.

You can apply Edit Poly modifier to your mesh, split edges there...

Than apply  Unwrap Modifier and simply delete Edit Poly modifier you used for edges splitting.

I'm presuming here that your mesh is already in edit/able poly state.

Thanks @domo.spaji ,

When I delete the Edit Poly modifier the UVW Unwrap Modifier seems to have lost the unwrapping I did for the mesh with edges splitted. But I copied that UVW Modifier and then pasted over and it works.

Thanks a lot.

Ah, yes, that changed some years ago.

And, yes. cut (copy-delete) Unwrap Modifier and paste it after deleting edit poly should do the same.

Maybe this is what you need: miauu's Transfer Edges Poly<->UVW

It allows you to transfer(convert) edge selection from editable poly object to edge selection in uvw modifier(uv edges) or to transfer(convert) edges selected in Unwrap UVW modifier(uv edges) to editable poly edges.

I had no idea it existed already @miauuuu , right now I´m using @domo.spaji advice and it is working but your script is exaclty what I needed.
