The SpeedTree Modeler, which runs separately from UE4, offers procedural and hand modeling tools that allow both efficiency and precision.
Note: SpeedTree 8 for UE4 is compatible only with UE4 4.19 and later.
Note: Files exported by the SpeedTree for UE4 Modeler will only work inside of Ue4 (.ST)
Note: Version 7 of SpeedTree should be used (.srt) if your project is in 4.18 or prior.
SpeedTree 8 for UE4 is available with a subscription that can be purchased here: https://store.speedtree.com/UE4/ The subscription will allow you to edit and create trees. Custom licensing is also available.
Included in the subscription application are these features:
Log in with a free SpeedTree Store account to export the new SpeedTree samples models to UE4.19. Export-only mode replaces our drop-in ready models on the SpeedTree store with a more flexible approach to bringing SpeedTrees to UE4.

Editing and saving is disabled in export only mode. For the full version of SpeedTree for UE4, simply activate a subscription through the SpeedTree store.
SpeedTree 8 for UE4 can open SpeedTree files (.SPM) and export them in a format specific to UE4 (.ST). SpeedTree 8 for UE4 will not export meshes outside of the .ST format and is incompatible with other game engines.
Using the SpeedTree Modeler is a three step process:
