Release Type: Official Release

Platform(s): Windows 10 64 bits

Describe the bug
When importing a .blend file created in Blender 2.8, the error "Error:An exception occurred while generating the template." appears and nothing ends up imported.

To Reproduce
Steps to reproduce the behavior:

1. Create a project in blender 2.8
2. Save it as a .blend
3. Load it in xenko by importing a model as .blend
4. The error will appear when importing

Expected behavior
The model should open properly without errors

Screenshots

Log and callstacks

Error:An exception occurred while generating the template.
Info:Nothing to import.

Additional context
It happens on any kind of blender 2.8 projects, I've tested with a project containing a complex model and with a simple new project only containing the basic cube, it always happens, trying with blender 2.79, the projects are imported properly, so something probably changed in the format between 2.79 and 2.8

No source file or test is identified in the issue. Start by reproducing the .blend import with Blender 2.8 and compare it with a Blender 2.79 file, then trace the model import path and the template-generation error. Done means Blender 2.8 projects, including the basic cube, import without errors or an empty result.
