This is what I see in ZE when I import my objects: the textures are shown as black.

But, when I play the game, the textures show up fine. The reason I want to see my objects in ZE is so I can detail the AI's pathway inside the buildings with boundaries, plans, etc.

How may I solve this? Thanks in advance.

place a light and make it a directional light
... u have no light in ur map...

But when I place an object from the assets folder, such as the Kamino bridge, it comes in clear. Is that because it has a default lighting already?

have you tried placing light yet? ether its the light or ur textures are the wrong format

Found what I did wrong. I went to lighting, and after all I didn't need to place a light. I only needed to deselect the "use default lighting" option. I only need this temporarily to place my barriers. Thanks for your help!
