blender waterfall

[JPulham]

How can I create a realistic water fall in blender, like Niagara falls or something where a large plane of water becomes foamy and then falls off the end?
can this be done with fluid sim or particles?

also, how do I make it a seamless animation (i.e. starting and ending key frames are identical)?

The fluid sim can spwan particles automatically now.

For seamless i just do half the animation, copy the Keyframes (action/nla window) paste and reverse scale (using s key). btw pasting 1 keyframe (the start one) at the end also does seamless but the interpolation is less "natural" looking.

Wouldn't your method cause the water to jump back up on the last half of the animation as it is reversed? (And placing the first keyframe at the end would also make it jump back up but very quickly as it interpolates from the last frame.)

a very basic way, if we speak of a walkcycle, is copy paste the 1st frame to last one, and perhaps export all except th every last if it's noticed a pause (2 frames equal)

of course, that's not all, you need to tweak it all very heavily, that is, *animate* , to have it as a natural walking.

[JPulham]

maybe do a simple fluid sim of half the full scene length, then copy the fluid sim and offset by half, and repeat that until you end on a key frame that is the same
i.e.:

Code: Select all

|------------------| full time line
      |---------| actual animation
| fluid 1 |
      | fluid 2 |
            | fluid 3 |

but this may be more trouble than its worth
