Thx Anvart for trying and reporting.
I was planning on an export dialog with some options (like export normals, float precision (nr. of decimals), etc...), and I will make the matrix rotation/translation optional as well. I was more or less planning to support multiple model export to one file as well (optional) which is why I had to get the translation/rotation to work in the first place, but I see your point that it isn't always useful.
Yes, materials are a bit screwed. I still haven't found the best way to export it correctly. The uv's get exported ok, but assigning them to the correct texture seems to be problematic with the FeelingSoftware plugin. I probably am doing something wrong though, so I am still trying to work that out...
