How can i export egg files from blender

There are a few options, depending on your requirements and preferences, I believe!

I put together a quick-reference covering them to the best of my knowledge at time of writing–you should find it here:

On the matter of “blend2bam”, note that it exports the entire blend-file, if I’m not much mistaken. If you want to keep multiple models within a single blend-file (e.g. variations of a single prop), or to have working elements within the blend-file that are not to be exported, then it’s a poor choice, I feel.
