Block colour / no textures on sketchup/.dae-Objects

I have imported models from sketchup using the .dae format and cannot get textures to display on them. They only appear as a block color please help!!!

Make sure the textures have been copied into your project folder in a directory called textures, nested within the folder where your dae files lived have been exported too.

[For future readers with a similar bug] I had the same issue. In the “Materials” tab of the sketchup model, I selected "Use external models (Legacy) under Location and this fixed it for me.
