Extension that fills empty faces?

[Mero]

Hi, this is my first thread on this forum.
Due to a bug when I need to import a .dae into another software, i need an extension that fill empty faces of all model surface.
I can make it selecting all surface, but this is so difficult.

Exist an extensions that make this automatically?
Es:
One surface with texture on all face -> make anything
One surface with texture only on 1 face -> other face automatically take texture of other face (or generic texture equal for all)
One surface with any texture on 2 face -> or generic texture/color on all 2 faces or show error.

Thanks for help

Oooooook, i find a solution

1. Build 3D model
2. create a plane XY
3. select all model and use a texture (not a color that have same problem). Paint this texture with paint bucket tool on first face of plane XY with all model selected.
4. select plane XY and make "reverse faces"
5. select all model and use same basic texture with paint bucket tool.
6. Build Texture preferred for exposed faces of model
7. remove plane XY
8. export without the bug

Happy to share this tips.
BBye

I found a solution without a extension.

1. make model
2. create a generic Plate
3. select all model + new plate
4. paint a generic texture on first face of plate
5. reverse face on plate
6. select all model + plate with reversed face
7. paint same generic texture on reversed face of plate
   now all face on model have a texture and correct normals
8. paint all texture you want on model on visible faces

Expot without normals bug.

happy to share this tips with you
