Funky Quad colors and Follow Active Quads now working

posted to: Cutting UV Seams

I turned on the Display stretched in the overlays in the UV Edit screen.  Instead of getting blue quads, I got some funky colors and some blue-ish quads.  I continued and Auto Aligned a quad into a square and tried to apply the Follow Active Quad.  Nothing happened.  Is this a 4.0.2 thing or did my Blender version drop some acid?  (For whatever reason now I can submit a photo?). Will try again after posting this.

    When using follow active quad, make sure when selecting all the quads, the quad/face you auto aligned is the active quad.

    Straighten the quads first, if the stretched UV's persist, you may have issues with your model, double verts, flipped normals or something else.

    Indeed wrongwright ,

    like Adrian said...you don't seem to have any quad active in your screenshot...

    ...and as for the colors, try changing the Stretch Overlay to Area (default is Angle, I think).

    The picture I used wasn't a good one to illustrate the Follow Active Quad, I had tried it a few times but didn't take picture.  Martin, I did change to Area, got mostly blue on the two side faces and green for top or tread part of the tire.  I checked the model for doubles, I haven't found any.  I've been watching the normals so no problems there.  I am trying several quads at once but that doesn't work either.

    Reverting back to previous save just because I couldn't undo anymore..but now that's going to take some time to redo.  Back after dinner or so.  Or will start fresh tomorrow.

    Did you apply the scale? Also it would be helpful if you could make a video of a screen recording showing what you are doing so we can see what might be going on.

    I am following the video as described, step by step. Maybe at the beginning we applied scale, or I did anyway because seems like that's the cause of most problems.  I checked many times for doubles.  I checked many times for normals.  Nothing.  All good.  I have redone this 2x already.  The next time I do this I'll make a film.  Sure, why not.  I may not be soon as I need to cool down, this is starting to get to me.  Thanks for the replies.

    You can also upload your file and we can try to straighten those UV's and see what the deal was.

    I'd rather post a file than try to post a video at this point.  Thank you.

    So, wrongwright ,

    What exactly is your problem..it works fine:

    Just press OK...(I disabled the Stretch Overlay and the Image, for clarity)

    Hey wrongwright
    I downloaded your file and tried 'follow active quad', it worked perfectly for the top island.

    Make sure you select the whole island and deselect the quad you auto aligned, then select it again to ensure it is the active quad.
    Then you should have no issue with the follow active quad option.

    You will need to repeat the complete process for each of the islands.

    ..and no, it doesn't matter if you Unwrap > Follow Active Quads in the 3D Viewport, or in the UV Editor.

    Odd, I got this by using the UV menu on the right side of the UV Editing window.  It did change but it isn't so square looking.6 at 12.37.01 AM.png

    As Adrian mentioned above:

    "When using follow active quad, make sure when selecting all the quads, the quad/face you auto aligned is the active quad."

    In the video (and screenshot), you have an Active Quad, but nothing else Selected.

    finally...I used a different square/quad and got a better result.  All from the right side of the screen, using the UV instead of the right-click method.  Why would it work there and not the other way?  Is bug or is my MacOS still not fully dev'd up yet? or what?  Not wearing the correct socks?  This has been frustrating.  Thanks for all the words everyone.

    It's not a bug or something in Blender! It's human error.

    Have a good night's sleep and try again tomorrow...

    Martin, I followed exactly as described in the video.  What I understand is I should be in face mode and select the quad and nothing else.  Just run the Follow Active Quads.  I have watched it over and over...starting at 11:11 in the video.  Maybe you mean all the other islands?  I haven't even touched those, I just did this island.

    You are not selecting all the quads on the island
    In Blender v4.0+ you need to select all the quads.

    We do advice using the version used in the course.
    By using a different version, what you see in the video may not be exact info. 
    A simple thing such as selecting the whole island is the only difference here, and we mentioned the solution at the beginning of the thread.

    Oh, sorry wrongwright ,

    I never used it like that, but in 3.6 this worked as seen in the Course, but in 4.0, you need to select the Island, that you want to use the Follow Active Quads as mentioned a few times before...so like this:

    As a note, it is better (for 'beginners') to use the Blender Version used in the Course, when following along.
