Harveytherabbit: I legit if I used blender would wonder if someone somewhere has made a semen preset for fluid simulation. I mean... let's face reality, porn in 3D is now very well established and widespread (giggidy) so it makes sense that it would be developed by those in the know and sold for like $20 so the collective cum of the 3d porn world can be raised to a better level.
Pilfry: Small scale fluid simulation is a complete nightmare. You can do a decent rough sim. I made a tool which does just that (though not in Blender) on essentially any input figure, but getting from there to a good render is borderline impossible. There are too many unsolved problems for cum-scale fluid dynamics in the context of rendering. That jittering in this animation is where the particle density exceeds the threshold for meshing, so it gets meshed, then the next substep the density reverts or progresses to where it drops below the threshold and it doesn't get meshed. That's not easy to resolve without working yourself into a corner or undoing all the benefits of simming in the first place. To be fair this shouldn't have been simmed. Completely pointless. None of the benefits and all of the downsides (like catastrophe of a mesh and arse-up shading).
Harveytherabbit: @Pilfry: Considering semen isn't technically a fluid but more of a gel, wouldn't that mean that the meshing dynamic variables could be more held together? Based on what you're saying too, I'm almost curious if a trick of making the models much bigger and letting the fluid simulation have a larger scale to work with would be a valid experiment. But I'm only a character animator, my knowledge of simulation is almost nothing.
