We’re transitioning all things RAIN over to our new product Sentio. We’ll keep this legacy site and these forums available for some time, and we just released an update to RAIN so that you can continue to use it on Unity 5.3+
At this point we’re pretty infrequent visitors to these forums, but are trying to check in from time to time (like today.)
Feel free to get involved on our newer forums as well at rivaltheory.com/support
Thx
