Whats up there, I see that there’s an possibility within the niagara baker for baking numerous attributes, although I haven’t the foggiest of how to take action, they’re all largely clean. How would I am going about baking out a circulate, velocity, or another attribute?
Thanks
I don’t actually have any answer as a result of I’ve by no means tried to bake movement vector from Niagara Fluid. (It’s horrendously electrical energy intensive.) Quite after a fast test I kinda have some thought why you possibly can’t see something from the Velocity Buffer.
AFAIC, the rate buffer solely offers you the mesh (in addition to particular person particle) velocity change of every pixel. Because the fluid area itself is “static”, it could not write something into the rate buffer. One other challenge is that every one Fluid supplies learn scene depth from the buffer which prevents itself from writing something into the buffer.
In all Gasoline 2D examples, you possibly can kinda get one thing from the “DataInterface – Velocity” within the baker supply, however it’s not normalized from [-1,1] to [0,1] vary, and the colour is so saturated which doesn’t appear to be helpful for movement vector.

Hello there, you possibly can strive TFlow for baking circulate maps.
You may give it any flipbook and it’ll output a circulate map flipbook, fairly quick, and it’s not electrical energy intensive

I’ll look into this, thanks for the knowledge on how the fluids are literally rendered, very informative! My coronary heart goes out to your electrical energy invoice.
I’ll positively test this out, it looks as if a extremely useful gizmo, expensive, but when it really works in addition to it says then I’ll get a variety of use out of it.
