  • Wind Directional Source not working in UE4

    Hi there,

    I just started with speed tree today. Tutorials I have watched show that setting up wind is as simple as dragging a wind directional source into your UE4 scene, however, when I do this my speed tree assets don't do anything. Is this because I am using the evaluation edition and free exporter? Or have I made a mistake?

    Thanks

    EDIT: Added an image of my scene. Wind is enabled and working in speed tree cinema and the exporter. Turning the radius up has no effect either.

    You need to add the speedtree node to the materials that are generated in UE4. I don't know why they're not automatically generated in the material.

      You need to use SpeedTree for UE4, not SpeedTree Cinema. With SpeedTree for UE4, you'll get wind and much more optimal exports. (The EULA for SpeedTree Cinema is also incompatible with UE4)

      Enable create materials and include vertex processing in the importer dialog

        Ah yes. I thought the exporter was only for that and the wind had to be setup in cinema. I now see that ST for UE4 has its own wind settings. Thanks a heap! I now have moving trees
