I encountered difficulties importing a model with two textured materials from sketchup.

SketchUp image with a brick and timber texture from JPEG maps.

Blender recognizes my two materials as different 'UV maps' on the dropdown menu. Online tutorials recommend deleting the second UV map (ID19) and replacing it with a LightMap.

However, after exporting my .fbx file and opening it in UE4, my second material disappears (brick texture disappears (color is there though!) but timber texture remains)

Could someone shed some light on how I can get the brick layer to come up? I am able to export with one single material on but not with two different materials on a model. I assume it is not to do with scale as the timber is scaled to the exact as the SU image.

    $\begingroup$ Unreal rather. but I still don't see how trying to get a brick texture to come up in Unreal is viable as a blender question. $\endgroup$

You replaced the brick texture with a lightmap. Try to skip that step and see what happens. Alternatively, you could texture the same thing in blender using material slots.
