I want to activate checkpoints while simulating a waterfall but for some reason as soon as the Checkpoint Interval is reached it deletes everything in the sim and goes on blank until the last frame is reached.
I am using more or less default values everywhere.
Is this some sort of bug or am I doint it wrong?

Hey!
Im not sure if you solved it already but in any case I just bumped into the same issue.
What I found out is that when you enable Checkpointing in the SOP Flip Solver, it for some reason doesn't pass the $SF simulation frame value, that is required in the filename, on to the dopnetwork inside the SOP Flip Solver node.
What happens then is that the .sim files get written without a frame value.
(FILENAME..sim instead of FILENAME.1.sim for the first frame)
The solver doesn't know what to do with that and the rest of the sim is blank.
To fix it you can dive inside the SOP Flip Solver and break the Checkpoint File Name Connection on the DOP Net in there and set it yourself to FILELOCATION/FILENAME.$SF.sim
My guess is that $SF doesnt even exist on SOP Level where the SOP FLIP Solver node tries to evaluate it, since it is the Simulation Frame. Therefore it returns a blank value.
Hope this helps
Cheers
