What i didnt see is a mass variable so particles could react with each other and transmit energy accordin to angle and speed of collision. doesnt need to be physically acurate( just use integers) as long as it gives artistically good results. Just my 2 cnts. keep up the good work. newtonian is good name einsteinian isnt relevant in 3d as time is already relative.

I hope to see this new particle soon in the main build. thx for the great work Jahka.

Took me forever to figure out how to make dynamic hair with that thing. Yay! Took me forever to figure out how to make dynamic hair with that thing.

There is a sort of limitation in the way animated textures are handled so that directly using movies/sequences with different timing doesn't work, but I am trying to figure out ways to circle around this limitation.

One of the limitations I encountered with the old system was that video or sequences applied as textures to the particles did not keep independent time. Instead of every particle displaying a frame of the sequence depending on its birth, every emitted particle displayed the same frame of the sequence at the same time. I didn't notice anything in the wiki about this, so I don't know if it's being addressed or what not. However this limitation is not exclusive to Blender, and I've seen it in game engines before. The solution has been to allow for segmented textures, say a single 1024x1024 image segmented into 64 or 128 pixels each. This has been used to allow a particle to display an independent "frame" of a segmented texture relative to it's time of birth/death. I hope to see something like this eventually, if it's not being added already. This is good news.
