Putting Materials on Imported Model from blender

Hi Guys. I have a 3d model from blender and I import it in my website
I removed the material of my model’s hair and replace it with a material from babylon but my problem is after doing so my model hair turns like transparent. not totally transparent you can see whats behind that mesh I tried material.backfaceCulling = true and still it did not fixed. Can someone help me with this


You can check if the mesh visibilityproperty. A value of 1 means no transparency at all.
I’m wondering if, instead of transparency, it is related to normals. Bad normals means having a dark color where it should be lighted.
Can you check with the inspector?

Other potential issue is zfighting: multiple faces at the same place. This will be more visible if your model has back faces with backfaceCulling set to true.

Also, make sure that your material does not have transparency enabled / alpha = 1:
