How to Resolve Texture Problems When Importing 3DS Max and Cinema4D Files into Unreal?

Hi, I’m still new to Unreal Engine, but I’ve seen this effect on simpler geometric objects. It looks like one side of the leaves remains transparent.

I was able to find some information:
If you’re encountering issues with transparency on one side of a 3D model in Unreal Engine 5, you can try the following steps to address the problem:

  1. Check Normals. Ensure that the normals of the mesh are facing outward correctly. In Unreal Engine, inverted normals can cause rendering issues, including incorrect transparency. You can visualize and correct normals in your 3D modeling software (e.g., Blender, Maya, 3ds Max) before exporting the model.
  2. Double-Sided Materials. By default, Unreal Engine only renders one side of a polygon. If your model needs to be visible from both sides, enable double-sided rendering for the material assigned to the mesh. In the material editor, select the material node and enable the “Two Sided” option under the Material section.
  3. Geometry Simplification. Complex geometry can sometimes cause rendering issues, including transparency artifacts. Simplify the geometry of the mesh if possible.
