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

Build 3D model
create a plane XY
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.
select plane XY and make "reverse faces"
select all model and use same basic texture with paint bucket tool.
Build Texture preferred for exposed faces of model
remove plane XY
export without the bug

Happy to share this tips.
BBye

I found a solution without a extension.

make model
create a generic Plate
select all model + new plate
paint a generic texture on first face of plate
reverse face on plate
select all model + plate with reversed face
paint same generic texture on reversed face of plate
now all face on model have a texture and correct normals
paint all texture you want on model on visible faces

Expot without normals bug.

happy to share this tips with you
