Hiya there, I see that there’s an choice within the niagara baker for baking varied 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 move, velocity, or some other attribute?
Thanks
I don’t actually have any resolution as a result of I’ve by no means tried to bake movement vector from Niagara Fluid. (It’s horrendously electrical energy intensive.) Fairly after a fast verify I kinda have some thought why you possibly can’t see something from the Velocity Buffer.
AFAIC, the rate buffer solely provides you the mesh (in addition to particular person particle) velocity change of every pixel. Because the fluid area itself is “static”, it might not write something into the rate buffer. One other concern is that each 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.
