Hi,

This is probably happening because the compiling wasn't finished or there was some error while it was compiling. The compiling automatically happens when you save the file. I would suggest resaving the file.

Let me know if this helps!

Hi!I try to import .spm file into Unity with SpeedTree For Unity,but when I save the tree using "save as" or "save as with asset",the .spm file is small.
For example,I open a sample tree,then save as without any editing,then the .spm file I got is smaller than the original one.
If I import that small .spm file into unity,then I get the error below:
SpeedTree file does not contain run-time data. Be sure to re-save it using the Unity-specific version of the SpeedTree Modeler.
So I think that SpeedTree For Unity lose something when save.
I have installed Microsoft Visual C++ 2010 SP1 Redistributable Package (x86),but don't work,
My environment:
OS:Windows 10
SpeedTree For Unity:V7.1.7
Unity: 2018.3.0f2
Thanks for your help.
