please test and give some feedback. We are developing 3DMLW and we also made support for .blend files.
There are 2 possibilities:
- Using .py script for export (see 3DMLW forum)
- Using .blend files directly in 3DMLW (experimental). See the example: hot.ee/blender3/
Right now only 32 bit files are supported.
As 3DMLW also has scripting, then maybe in future there will be possibility to use game engine features in 3DMLW.
