Spikes/Needles after exporting snowy mountain landscape from Gaea to Unreal Engine

Hello, I’ve created a snowy mountain in Gaea, but after importing i get completely different “spike like” landscape shape. I’ve tried deleting and relocation of almost all nodes in Gaea, but the issue still persists. Also, I’ve tried different options for exporting from Gaea. After I’ve tried to fix this issue, i saw a dependency: most probable the issue is with Texture and/or SatMaps nodes in combination with Snow node. I am new to Gaea so I could have missed something, please give an advice. Also, I’ve recorded the issue and it is accessible via link: https://youtu.be/C9e33hEmOUs

The export is wrong, or the file you are importing is wrong.

PNG16.

Also, based on what you are getting as a result, I think that’s a splat map representing where the snow is supposed to be.
Meaning maybe you have multiple files as output and just picked the wrong one.
