I have tried to place a material on to an object imported from blender and it’s not showing up correctly.
The material works OK on a cube that I have created in the engine but on the imported cube it just goes grey.
I’ve tried to upload an image but it wouldn’t let me.
Any ideas why this would happen?
First guess - make sure you have UVs (texcoords) set properly on the mesh in Blender before you export it.
Thanks. That fixed it 
Excellent.
