Hello again! Been a while, had a quick question that I can't find a direct answer for in the forums.
Quite simply, I'm curious if Obi fluid can do a proper 2D simulation. Basically, I'm using Zibra Liquids and kinda tricking it to work in 2D. It runs 3D, but by tweaking the values enough (gravity, viscosity, etc) and keeping the box just barely bigger than a particle, it will kinda act like it's 2D. The problem now is I updated to the latest version, which changed the effectiveness of some values, and it's a pain in the ass getting it to work properly again. It will sometimes slide down the front and back invisible walls of the box.
So ya, curious if Obi can pull this off and just totally ignore Z depth. Also, how sticky can the fluid be? Zibra struggles with super sticky fluids, and now the fluid is bouncing off walls since the update. Even with friction maxed out.
Final question, I see you have GPU simulation arriving with obi 7. It looks like a similar structure to Zibra with a 3D bounding box. Will the GPU version be able to do 2D sims?
Thanks lots! I see you're very active in the forums and I appreciated the quick response last time I was here.
