Hi there there, I see that there’s an choice within the niagara baker for baking numerous attributes, although I haven’t the foggiest of how to take action, they’re all principally clean. How would I am going about baking out a move, 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.) Fairly after a fast test I kinda have some thought why you may’t see something from the Velocity Buffer.
AFAIC, the speed 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 will not write something into the speed buffer. One other problem is that every one Fluid supplies learn scene depth from the buffer which prevents itself from writing something into the buffer.
In all Fuel 2D examples, you may 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 may attempt TFlow for baking move maps.
You can provide it any flipbook and it’ll output a move map flipbook, fairly quick, and it’s not electrical energy intensive
