Missing metallic texture after fbx import from blender

Hi,

I am pretty new to unreal, I imported my mesh as a fbx with path mode to copy and embed texture, but my object doesn’t look the same. I discovered that only the base color, roughness and normal are imported. The roughness goes automatically to metallic and my metallic map isn’t there at all…nowhere in the soft.

I tried to uncheck the sRGB box but still don’t know what to do with my missing texture.

I made my texture into substance painter by the way and set them into blender before exporting to unreal.

If anyone knows a solution, I woud be very grateful to have it, thanks !

you have to import your fbx separately from your textures, also the Blender material is not compatible with unreal

Connect your metallic texture into Specular IOR Level input, it will do the trick.

heey can you show me a screen shot about that and does this work with blender Principled BSDF?
