• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

Blender What's your work process for making UV layout guides?

Hello all,

Just getting into Blender and one thing I am trying to do is see if there is any easier way to make a UV layout guide (a guide sheet with all the UV mapping on it to aid texture painting but more importantly, to avoid parts overlapping and accidentally re-using part of a texture).

What I am doing at the moment is loading an image (my UV layout guide) into the UV editor, I then align my new UV above that to avoid overlapping any other parts. Then export the new UV map, load that into the paint program, copy and paste it as a new layer onto the UV layout guide, export that from the paint program and reload it in Blender. Is there a add-on or other method that can do this all within blender? Something that will take the current UV layout and write it onto the guide image so I can avoid exporting and merging and reloading.

I usually simply wait with the UV unwrapping until I all parts for that uv are fully modeled. Once they're all done, I select all parts that go on one UV map, go to edit mode, press "a" (select all) "u" and select "unwrap". This will unwrap all parts at once and arrange them on the uv map. Once that's done, I go in and re-arrange to make better use of the space.
If I were to use Photoshop, I would then export the UV layout, import it into photoshop and start painting.

To export the UV map ( that is after rearranging) you can export it from within Blender -> UV Editing -> UV (see image).
