LW importer for Unity

As designed.
This material has an Image Map applied to the colour channel which uses Planar mapping. There is no image assigned but this doesn't matter, the mapping is still unsupported and LWO Importer will still (correctly) show a warning.
Just remove it and the warning will go away.

Got it. So planar and Cubic can be applied so we just get information from importer?
This "problem" is attach to the biggest problem: automatic assign/create surfaces after importing to be EDITABLE. You told me that, this directly is impossible as external part of UNITY …but can be done in other way: like special procedures in LW Importer?
If you can do it that would be great feature.

Yes it won't break the importer if you have models with mapping other than UV-Mapping. But if you need correct texture mapping you must use UV Mapping.
Try the following workflow for editable materials:
- in the Project window create a new folder, call it materials (or something similar)
- Find your imported model, open it up in the project window (press the down arrow) and select all the materials.
- Press Command/Ctrl D to duplicate them.
- Drag the duplicated materials into the folder you just made.
- Go to the Inspector for your imported model and check 'Remap Matching Material Names'
- Hit Apply. All those duplicated materials are now being used in the imported model and they are editable.

Yes I do it in this way.
