Hello! When I import a Twinmotion 2022.1 project into UE4.27, all the trees in the scene lose their leaf and bark materials.

Hello! When I import a Twinmotion 2022.1 project into UE4.27, all the trees in the scene lose their leaf and bark materials. There is an error message in the load log "unsupported material MI_leaves". I'm using the Datasmith plugin for UE 4.27 and Twinmotion Content For UE4. I did everything as written in the documentation and in the video tutorial on the Twinmotion YouTube channel. But nothing works.

Equipment:

UE 4.27

Twinmotion 2022.1 (Trial)

Windows 10, i7, nvidia rtx3070, 16 gb ram.

All other assets are displayed well. All bushes and plants are imported perfectly. But the trees completely lose their materials (leaves and bark). On some fruit trees, the fruits remain, but there are no leaves and bark.

also some flowers lose their materials.

Does anyone know how to fix this?

I plan to use Twinmotion in conjunction with Unreal Engine. And if I can't fix the problem with the leaves and bark on the trees, I won't be able to buy a full license.

Another thing: I tried to take the tree assets from the "Twinmotion content for UE" plugin into the content browser in UE and transfer them to the stage, but they are also inserted without leaves. And when you open the material of the leaves - it becomes gray (without material).

Hello ,

Thank you for posting in the Twinmotion community and sorry to hear about the troubles. It looks like the tress are supported at this time with the plugin and it should work. I recommend you make a post in the Unreal Engine Forum so they can best respond and address this.

Thank you,

I fixed this issue! I reinstalled both plugins (Datasmith importer and Twinmotion content for UE 4). I also updated Unreal Engine to version 4.27.2. Now everything is working great!
