Dyverso Viscosity and Initial States

Hey Guys,

I've been working with the new Viscosity Material in Real Flow 10 and found a pretty serious problem. When I need to freeze the timeline so I can fill up a container, I save it as an Initial State. Only problem is, when I want to reset to the Initial State, the particles start acting crazy, ignoring gravity among other things.

I wanted to post some pictures to show but it the site won't let me. I must have reached my upload limit too.

Thought you all should know anyway. I wrote to Alex at Next Limit and let him know all the scary details. Let's hope they can fix it.

Hi Oldcode,

yes, the attachments are all full here. Use a free upload-site such as or a file sharing service such as dropbox or similar.

Maybe you can share the project file? (not if it is from the demo of RF10 because that cannot be opened by the standard version...)

Thanks Christian,

Yeah, I'm using the demo for now. Here's three pictures that show you what's going on. I've got the timeline frozen at Frame thirty. Because Real Flow crashes ever now and then, I need to occasionally stop the simulation and save the initial state. If there is a crash and I need to reset, you can see what happens to the particles. This is only two frames of simulations beyond the initial state. Without the ability to use an initial state, doing simulations with large numbers of particles is all but impossible.
