Currently the Worldeditor only has support for Speedtree 4.3 and older versions which were using the .spt format and is too old, by upgrading speedtree to use the SDK for version 5.1 or higher we will be able to use files with format .spm which are the new format and will allow us to use the library we already have with more than 700 high quality trees.
