Hey for anyone having problems like liquid completely passing through the collision effecter (cup), you for some reason have to set the surface thickness to at least 0.5 for it to work, while the default is set to 0

For those having issues with the mesh not appearing:

Go to the first frame on the timeline, then click the "resolution divisions" field in your fluid domain object, and press enter without changing the value to anything new. Now play the simulation and it should have updated to show the simulation and mesh.

The same bug occurs even in Maya's Bifröst simulations. These kinds of bugs MUST be fixed!

im getting lost at 4:34 making it mesh doesnt get rid of anything, it keeps the domain as is and i dont see any flow when i press space bar plz help

Hey, Cbailyfilm. I always loved making fluid simulations with mantaflow, but there are so many settings you have to mess around with to make it look right. Thank you for this awesome tutorial that explains everything very well.

If anyone's having trouble making their cups fill up like I did, increase the effector's values and test it out - that fixed it for me

I hope there will be more of these tuts about fluids...! Well done!

As I watched the video I kept wondering when the inflow would be changed to resemble more a coffee pot but then I realized it looked like this in the final render and I did not mind when I first saw the render . nice tutorial 👍

Can’t leave without commenting on how great this tutorial is, its fast yet easy to follow and even fun to watch. Thanks!

Awesome tutorial! I hit a brick wall in the middle that had me stuck for a little bit, but I figured it out. If anyone encounters an "Unbaked guides" error above the baking button, there is a checkbox for "Guides" in the just below the "Liquid" checkbox in the Domain options. Just uncheck that "Guides" box, and you should be good to go!

Decided I wanted to make a head in a jar, I've done some fluid sims in the past, but it's been a while. Of course, I started running into issues with leaks, then I realized my set up was wrong had to come back and peep this tut, so thanks again brotha. I appreciate all you guys who put out helpful content like this. It's a godsend for aspiring artists and filmmakers like myself. Big thanks homie!

Thank you! Great tutorial. Thorough but no fluff and concise but not annoyingly fast.

completed this a week ago with a coffee cup and went to do it again and couldnt get the technique to work. I finally figured out that I had to add a little thickness to the container so that the normals inside could be flipped the correct way. Thank you for the tut!!!!

hey guys!
for those whose fluid is spilling out from the bottom of the cup u can try the following
1. make your cup thicker
2. select your cube, sphere and cup and scale them up at once and try baking at different variations of scales...(u might wanna use replay as the type of cache for this )
3. change the size of the sphere (try different variations in replay type)
4. change resolution divisions by factors of tens or fives.
IF YOU KEEP THE RESOLUTION DIVISIONS SAME YOU WILL HAVE TO CLICK ON THE RESOLUTION DIV. VALUE AND JUST PRESS ENTRE WITHOUT CHANGING FOR MAKING THE CHANGES YOU MADE WORK
i guess it will solve the issue if u do this
I did the same ...i just kept my res. div. to 5 and thickened my cup and scaled all of the objects up ....then i scales my sphere down...
i did all this in replay type
