Illusoft has taken up the development of a COLLADA 1.4 export plugin for Blender ! Great news !
that’s great news … better if anyone can confirm that blender exported dae’s can be imported in xith
(no offense agains croft but there have been issues in several blender exporters yet)
I agree, I was really glad to hear about them doing this! I am hoping the exporter will in fact work along with David’s loader, I am planning on using the COLLADA format for the project I’m currently working on. 
I’ve noticed they have released a version of the plugin already, but I am going to at least wait until they have texture exporting implemented…
So will I.
