Thanks for getting back to me Aleksandr, and a real shame about the crowdfunding - as you say on the pitch, there's really nothing in this space... I'll keep trying with the demo, as a mountain biker myself it's realism that I'm looking for but the push back on the controls did seem excessive, maybe it's my setup... I've recently been getting into a motorbike sim that gets the realism balance really nicely called gp-bikes - really good and the free demo gives you a good idea of how it performs if you want to give it a go... The developer of that also does a Motorcross one that incorporates the sort of bike balance that you're attempting. As I say, I'll give yours more time, let me know if you want any feedback on progress - I'm an animator who uses 3d a lot so was really interested in the track editing you were proposing...
ps I just tried the arcade mode and it's much better, I guess I'm not ready for your hardcore take on the full realism :)
one thing that I noticed that would be really useful is a chase cam, the near 3rd person one doesn't rotate with the bike and without real physical feelings to inform of your rider's orientation and bike / rider position it is pretty difficult to get the trails ridden well. Starting to get the feel of it however, cheers!
