It's been a long time without updates, sorry about that. I had an exam period at university and had to focus on studying. But now I'm back. :p
This weekend I decided to update Dynamic Paint baking system. Currently it freezes the whole user interface same way as particles and smoke baking. In the recent SVN it's not even possible to show the process at mouse cursor anymore... Fluids, however, use this new "Jobs system" that processes bake in the background. It seemed quite easy to apply same system to DP.
Unfortunately it turned out to be impossible. Current jobs system crashes if you change animation frames within the bake process and it appears to be quite tricky one to fix. Most likely won't be fixed anytime soon. So I had to revert Dynamic Paint back to the old baking system. :(
Anyway, I have updated Dynamic Paint patch so it's yet again compatible with recent SVN revisions. Now I'm going to finish the second part of my Dynamic Paint guide. I guess I'll be able to release it by the end of this week.
