CItyEngine2019 import Unreal Engine4.25 All materials are missing

Nico — Thu, 27 May 2021 09:09:29 GMT

Save as .udatasmith

Import UE4 with datasmith plug-ins

There are only two folders:Geometries and Textures

There is no material on the model

How to solve this problem?

Any help would be much appreciated.

Thanks.

Hi Nico.

Thanks for reaching out.

Could you open the "Output Log" in Unreal (Window → Developer Tools → Output Log) after importing the Datasmith file and check if you see any related error messages?

If you don't find anything, could you send me a zip file of the Datasmith file and asset folder (building.udatasmith and building_Assets) so I can investigate further?

Best,

Benjamin

I found this document just now

I do not really understand the CGA , I used the default CGA

if I need to change something about it, maybe I should learn the CGA from the beginning

But I'm only a designer,not programer.It's too difficult for me ,ha-ha

That start rule really should not be the problem. It's only doing basic texturing rules and none of the new PBR materials creation. In that case, it just creates some simple base materials from your textures. But your materials folder is completely missing. Could you screen capture your export settings from CityEngine to Unreal Engine?
