  1. I have a scene where I am dropping a bottle into a flip tank all at small scale. The issue im having is that I am getting a quite a large space/void between the bottle and the liquid. Im trying to reduce this and make the liquid hug the bottle more in the beginning and not blow outwards and make this gap. The setup is an RDB of the bottle falling using gravity from around 10cm into the tank, both the RDB and Flip have been slowed down to 0.025 in time scale. I tried a number of things like lowering the velocity scale, upping the subframes from 10 to 30 in the RDB and upping the subframes in the DOP network to 4/5, and changing the surface tension and viscosity, but it still happens. There is no problem with the collision guide and I dont have any sort of surface offset on that either, it matches the bottle perfectly. You can see in the attached screen grabs that the bottle has barely entered the fluid surface but has created a large void underneath it blowing out the liquid. This is the sort of splash im aiming for: https://www.youtube.com/watch?v=npAuLi1y5AA Dramatic but close and not blowing out internally too much. I know my bottle is a different shape to that reference but my sim seems way off and I cant seem to figure out how to lessen that gap. Any suggestions I would be very welcome as nothing I seem to try is making the gap any smaller. Thanks!
  2. Cable Overheating

    Hi everyone, For an upcoming project, I need to create the effect of an extension cable overheating. ie. holes being burnt in the plastic casing of a wire and then smoke emitting from them. This is a good reference, particularly the shot at 1:26 https://www.youtube.com/watch?v=jGPkkOU3Uf8 The problem I am currently having is that for smoke to emit from these little holes, the source volume has to be really tiny. This requires a ridiculously low division size just to get the sim to work, making it impossible to easily preview the simulation. I'm thinking there must be a better method for doing this, so if anyone has any suggestions, I'd be happy to hear them!
