I agree that importing animations can be a ball-ache. Unity and the like have a store where you can buy such things which are pre-tested to work as described. That is a major bonus. With JME it’s a bit hit n miss unless you actually know what you’re doing. Im certainly not an artist - I hate 3D modelling and anybody that likes it is a crazy crazy person.
Having said that, there are a lot of areas that could do with some extra hands - It’s up to the people that use the engine to say “hey - I had a problem doing X and I came up with this solution - is it of any use to you?” - and thus the world continues to rotate.
I’ve written quite a few games using JME but never finished any. I’m probably the 90% of the users right there. But there are, have been, and will be some really nice looking games made using the current engine.
A game called chaos is one I’ve been keeping my eye one lately - as well as some of the really really talented coders like @nehon and @thetoucher and @pspeed for his intimately wierd knowledge of java. Check out this youtube channel. The names I have mentioned are a tiny piece of the talent around here. Ask the right questions and they appear from nowhere blowing your mind.
