I am using Autodesk Maya for creating models and animations of this character. This character appears and animates perfectly on all other platforms like Unity, 3dsMax, etc. but when I import .dae file in Xcode the face of the character appears green and not showing the perfect texture.

/this image have a view of a green face issue/

This model has perfect UV's on the face, other faces are used as blend shapes those shows perfect texture. UV's of the main face which appears green.

/this image have a UV coordinate info of face/

The face appears in Unity

/model appearance in unity/

What changes are required to change green color appearance of face to normal?

If any Maya material appears as green surface in SceneKit, you should delete a UV-mapped texture in Maya (check whether you're using Lambert, Blinn or Phong shader) and re-apply UV-mapped texture from scratch.

Green surface usually means a 3D object doesn't have a shading group assigned, or shader is somewhat corrupted, or error appears during import.

If you can't reassign a UV-mapped texture in Maya, try to assign this texture in SceneKit's Scenegraph. For that select a head and using Diffuse slot in Material Inspector choose a texture from a drop-down menu (the best image format in this case is .jpg on .png).

P.S.

I've found that your model was locked in Maya. Check ChannelBox and AttributeEditor.

  • @DayDreamer, have you achieved a result in this matter? If not, share your model via file sharing service, like https://dropmefiles.com. I'll take a look. – Andy Jazz Jul 12 '21 at 08:35
  • Hi, Andy Fedoroff thanks for your reply. I tried all solutions you suggested but the face still appears green, Here I am sharing the images and clips of my settings so you can get the idea. – Day Dreamer Jul 12 '21 at 11:41

  • You've shared pictures and video))). I said about model... – Andy Jazz Jul 12 '21 at 11:47
  • Share just a green head. I do not need a whole model. – Andy Jazz Jul 12 '21 at 11:48

  • I've found an issue. Your geometry (green head) is locked. I can't choose it in `Scene graph`. Check this out in Maya. – Andy Jazz Jul 12 '21 at 14:22
  • Check `Channel Box` and `Attribute Editor`. – Andy Jazz Jul 12 '21 at 14:29

    Thanks, andy I have unlocked the model using this way https://drive.google.com/file/d/1bfGwRLHzlxwWIl4ZjAQ7LlTOb1UjZvab/view?usp=sharing You can check in your Scene graph here is link https://drive.google.com/file/d/1ZWsSNZRQXojVuIVOB-Zk7dybR38P4QEG/view?usp=sharing – Day Dreamer Jul 13 '21 at 11:46

  • Sorry I can't continue the discussion in chat. I'm busy. – Andy Jazz Jul 13 '21 at 18:45
  • I tested v2 model. The head is still blocked (locked). I cannot select it in Scene graph. It's 100% Maya's issue... – Andy Jazz Jul 13 '21 at 18:48
