When using a material preset during model import, Write for the Depth Test is always disabled for the materials, even if it's actually enabled. All other settings and individual textures seem to be imported correctly.
I tried it with the following model and preset.
Model.zip
It also seems to be always disabled, even when importing without a preset.
It only works if you apply the preset in the material editor.
Additional suggestion: Apply multiple material presets during import using suffixes. This would allow you to apply presets to specific materials and you wouldn't be limited to one preset per model.
For example, the "mLava" preset would be applied to all materials that have "mLava" appended to their name, such as "LavaSurface_mLava".
