Here's a snippet from the manual, on the Playback Mode options in the MDD and PFX playback dialog:


"Playback Mode:
Normal- Plays back all Motion settings of the .mdd file.

Local- Plays back based on the local translations (move, rotate and
scale) of the object. Allows a .mdd deformation on an object while
respecting new motion applied to that object.

Distance Map- This adjusts the motion data to the movement of the
object. When the speed is 100%, 1s (second) of motion data is used to
move the object a distance of 1m."

Can someone please enlighten me as to what the hell the Distance Map option would be good for?

A common use is to MDD scan an animated model walking in place and apply this baked animation to the unrigged mesh.

Cloning this model and driving the clones with particleFX allows to create (semi)convincing crowds where each character auto-adjusts its stride according to the actual distance traveled.

Kinda nice. :D

OK.... going to have to look at that very hard, to see how direction is established.


My major point: that is some really confusing text. If the dox were open source, we could make it clearer, and/or provide some examples as you did here.
