Materials lost when SKP to UE4

HI,
I use the new 4.24 version, when trying to import UE4 with sketchup, all materials and colors are lost, and the material instance balls are all white.But there are texture files in the texture directory,What went wrong?

Can you wetranfer me the skp model? We are going to look at the problem Please send it to pierrefelix.breton@epicgames.com with your name and description.

Prior to do so, have you updated the Sketchup export plugin? Both the export plugin and the unreal engine versions must go hand in hand
