Bounds could not be determined

[Ash_of_Woods]

Hello, this is my first project and I’m new here. So, I’m not sure whether this is a common problem or something different. Anyway, I’ve been trying to download some assets, and everything was fine except for the trees. They can’t be seen in the demo scene, and I get warnings like “The tree couldn’t be instanced because bounds could not be determined.” When I try to add them to my terrain, the system says “LOD group component is not supported.” But all other assets work fine. What could be the problem? I’ve looked for this kind of issue, but I couldn’t find a solution. Has anyone else seen this before?
