We got it to work with 4.14 some time ago, but the solution doesn’t work with 4.21 due to compatibility issues (macros in RHI changed and there isn’t much documentation). We also got it to work with Unity (good documentation) and everything works same fast as in our demo. However, our further tests revealed some problems. There was too much overhead, when our fluid should have interacted with other physics frameworks (PhysX / Bullet), due to different data representations etc. After some analysis we concluded we can do much better:) and decided to do our own semi-ML rigid body / destruction solver. We’ve been working on it in the last half year and so far all finished components look very promising. We do not want to publicly release anything before it is all practically useful without much support from our side.
