Can't make the Wind Directional Source work on imported Speedtree mesh
node
I encountered a problem when importing the st. file into Unreal Engine 5. When I added the Wind Directional Source in UE5, the tree didn’t move. I wonder which step I did wrong. I tried many ways to fix it but haven’t resolved the problem yet.
-I tried to add Speedtree or Speedtree Wind node to the World Position Offset in UE5, but the tree is acting crazy.
-Then, I tried to export it as st9. format from Speedtree. The tree automatically shook when imported into UE5 without adding the Wind Directional Source, but the opacity map was not acting well.
Below are some screenshots of my settings.
Does anybody know how I can fix it?

You need to have the materials setup correctly with the speedtree nodes. There's several different configurations you need.
If you have "create materials" checked in the speedtree import options it'll auto-create some materials that will work. After you've done this I'd look at the shaders it makes and see what they're like. You can make your own based off these.
You can read more info here:

Thank you for replying! I checked the 'create materials' box when importing into Unreal. But somehow, inside the shader, it doesn't have any SpeedTree node created. Based on that, I manually added the SpeedTree node to the World Position Offset to all shaders/materials and adjusted the options on the left, and it works! Before, I just tried to add the node and didn't change the options on the left.
