JCW {l Wrote}:I work with blender and like to contribute something to the game.
I started to remodel the bow and the arrow did not change the texture so it's still the same.
Nice! Would you like to be attributed as JCW, or do you have another name under which you'd like to be credited? Are you also OK with the models being licensed under Creative Commons BY-SA 3.0? Once those two things are settled, I can include your models.
JCW {l Wrote}:But the blender export tool does not work (using blender 2.69.8)
It works here, at least. I'm not sure how badly it failed for you exactly, but if you got the add-on enabled without errors, it should work once you have explicitly marked your objects for exporting in Properties > Object tab > Lips of Suna > Exporting Settings.
JCW {l Wrote}:1. Is there a limited poly count for models?
There's no strict limit, but you should generally keep the level of detail such that the details are still noticeable under normal gameplay. It depends a lot on the model, but if you want some rough numbers, a human-sized creature could be 1000-2000, a large weapon about 500-1000, and a smallish item somewhere around 100-500 polygons.
JCW {l Wrote}:2. Is there a list of models which are needed or should be remodeled for the game?
There's an incomplete
list of needed models, but there isn't exactly a list of models that should be remade. Some of the weapons are pretty placeholderish, though, so having a look on them might be a good starting point for that.
