Importing from Blender

I have created a duck in Blender and it has a few different materials and each material has its own particle system. In Blender, this looks okay and everything is good. However, when I try to import the duck from Blender to UE4, only the shape of the duck and the material borders actually got imported. The colour properties of the materials didn’t import, and the particle systems didn’t import. Is there something I’m missing? Is there a way to import the duck WITH the material colours and particle systems still in tact so that I don’t have to recreate them in UE4? Please tell me soon!

Blender Material ID and Base color should be the only thing that can successfully be exported from Blender to Unreal. Blender particle systems can’t be exported into Unreal. You need to recreate it using Unreals particle system.
Blender Materials (except for base color as far as I know) can’t be exported into Unreal.
Blender Vertex color CAN be exported but the Unreal Material needs to support vertex colors.

The normal practice when using Blender to Unreal is to create a new material in Unreal and set it up in Unreal manually. The Blender and Unreal shaders will never be the same and the Blender FBX exporter still has issues with exporting materials properly so it it better to do it manually.

It is a shame I can’t just do it all in Blender. But thank you for explaining it, I needed that. I’m very new to both Blender and UE4, so I might be asking a lot of questions.
