This is a kind of bed news for me. Do you know by any chance whether the latest beta is better with this respect?
I just found the following page: http://colladablender.illusoft.com/cms/ it says that this plugin supports collada 1.4.1. In contrast, on my default installation of the Blender 2.49 the info about collada plugin says that it supports version 1.4.0. So maybe it make sense to try the new plugin or maybe it is already integrated in the latest blender beta?
I have used 2.56 (the latest beta) for the modeling and texturing of these models, but the exporter for 2.56 makes it crash (and loses a few minutes of work) So I opened it in 2.49 and used that exporter.
I am using the Linux version of Blender and will experiment using the windows version, and see if it still has this problem.
I don’t know how thoroughly you looked at that website, but that is the exporter for 2.49 (or earlier) and it hasn’t been updated since 2007, well before the 2.5 series was released. And the forum has been taken over by spam-bots.
Also looking at the ‘progress’ page it seems that they were working on the constraints when the project stops, and these features are listed as ‘ready for testing’. I am not sure if this means they are in the release I am using, or if they haven’t been put in the released code yet.
So does it essentially means that there is currently no way to export constraints from Blender to COLLADA format? If true, than it is really sad because I think it is important for any gaming technologies to be able to work with constraints and AFAIK collada plugin for Maya and 3DMax can handle constraints export very well.
Maybe some other forum readers can shed more light on this topic? Or should we probably start different thread somewhere else to discuss about the way to export constraints an general physics support in Blender’s collada exporter?
