Why does my 3D model look like this when I import it to Flax Engine?

Why does my 3D model, which I’ve imported from a 3D low-poly program called Crocotile3D, looks like this? It looks transparent for some reason. I can see the texture, but it looks transparent and weird. Can someone help me out? Thanks.

Open the material of the model, maybe the auto-imported material has flaws. Adjust it for your needs.
