I was playing a bit with Liquigen and exported a scene to mesh of 208 million triangles, imported in Keyshot Studio. After rendering I used Topaz Video AI to slow it’s speed to half. And finished it all in DaVinci Resolve.
Thought the result was pretty funny, it’s not supposed to be anything but still…
This is awesome!
Did you use DOF in KS or do it post?
It’s like a chew 5 gum advert. Would love to see how it would look with the surface as part of a subwoofer
Thanks! The DOF is also from KeyShot. There was an odd bug though. I rendered the entire animation twice before (as stills) and in both cases it rendered completely different frames. I’ve to check if this is an actual bug which can be reproduced since it’s quite annoying to find out.
Decided to do a 3rd attempt after closing and opening the scene again and that worked suddenly. It’s not that it rendered for a long time, samples are only at 128 I think.
With the keyframes of the camera animating DOF got so much easier. In the past it was a separate thing but now you can just set basically all camera settings in a keyframe and it saves a lot of time.
Having the liquid animating with an animating object like a subwoofer would really be a nice experiment. Think it will cost a bit more time but worth to see if it’s possible.
It’s cool! Liquid is not an easy topic. 
Did you use keyframe to move the camera? How long did you render for the animation? Was it rendered by GPU or CPU?
Hi Norman!
I used keyframes indeed, think that’s the easiest way since you can also animate DOF etc together with other things like positions.
This rendered in 20 minutes on a 4090. I did double the frames using Topaz Video AI because I thought it would look cooler slowed down to half the speed.
I can test if you want but I think if I disabled the motion blur in Keyshot and DOF it would be faster. I enabled denoise and only used 128 samples. There are also no special lights besides an HDR.
This was just one of the demo scenes in LiquiGen and I wonder if it also is possible to not only render the liquid but also the foam, like if you pour coffee into a cup. It does add particles for it but not sure how they will combine if you render it out to a mesh.
Calculating fluid flows is a pretty extreme task for a computer but it’s amazing how things get powered/optimized using a GPU. You see the same if you look at Flip Fluids for Blender. No experience with that plugin (and Blender) but those demos also look really impressing.
I once also tried Embergen which does smoke/fire simulations which you can export to VDBs. Unfortunately KeyShot can’t import VDBs as a sequence (every frame a unique VDB) and KeyShot doesn’t support multiple channels so you have a ‘fire’ part and a ‘smoke’ part within the same VDB.
I’m also not sure if people would use it enough to get the feature in, I do think that it can easily impress people if it was possible and got rendered at a fast pace as well. That, in return, could more people trying/buying KeyShot
edit
I took a quick look at Flip Fluids but it’s CPU driven in it’s calculations which is not bad but mighty slow on my i9-9900k 
Thank you for the details! I’ve learned a lot from you. Your skills and great tools really show in your work! 
Thanks! I learned a lot from all users as well, it’s fun to try to figure out issues and helping people out. Also love to test different pieces of software takes a lot of time but currently I have some and think learning now is more fun than when I was young
