Inverted UV islands?

Recommended Posts

Hello wonderful members,

Since upgrading to R21, I've been frustrated with black UV islands!
After generating uv in Cinema, once applying the texture file, or generating textures in other apps, I end up with black? inverted? UV islands!

Normals are aligned, no matter the projection I use (frontal/flat)

as you can see in the Rizom window ^

 

I used the same workflow before in R20, never faced this issue. I have to unfold the darker islands in Rizom to fix it, it seems like it mirrors it, invert. IDK. is there an explanation to this so I can avoid it in the future?

Thank you.

Do you have the SP1 update to R21 ? (.115)

  • Yeah. I also have other funny issues, like snapping not working sometimes. it feels like a clean reinstall :S

    That is very odd. Please do a support ticket about this, including the scene file.

    We could also do with a look at that, which might give us a better understanding of what is going wrong, or what can be done to circumvent it...

    So I thought that this issue was related to me importing scan mesh in FBX from Agisoft Metashape. I decided to start clean all from within Cinema 4D. but yeah, it is happening with meshes created in Cinema too.

    Attached is a simple scene.uv_issue.zip
    1- Created a platonic   2-made editable  3-deleted current UV tag  4-selected few edges for UV  5-Paint setup wizard for a new UV tag  6-Projection Flat  7-relaxed using ABF with cut selected edges

    @Rectro do you know anything about this issue? Sound very strange! I will have to dig it a bit more!

    I have just standard result from your scene (as expected, nothing special)

    Can you post screen of your result?

  • So I am assuming it is either when exported to FBX or only on my computer.  another funny thing is that it for some reason reverted my Cinema to the older .022 version, I checked Yesterday when Cerbera asked me and it was .115! I guess it my windows. anyway, I'm attaching another scene, with the exported FBX this time, and a video of how this looks. sorry for the watermark, but the windows built-in recording sucks!

    Another observation  was it always happens to faces not facing the camera when projecting!

    I ran the updater and it showed no updates available 😄 ... I will restart and try to check what version this time will show, then maybe a clean re-install.
