Hey guys, I am trying to develop a pflow system that would generate sparks as well as smoke upon an object that hits the ground and then drags along the surface. It basically has to look like metal of a car grinding across the road in an accident. I have done my first attempt and was wondering if you guys could have a look and suggest improvements.

At the moment the green coloured particles are the sparks but I feel I need them to move away from the object at pace. The blue particles are still to be developed better but they are to be used for smoke/dust generation further down the pipeline. Anyway here is my scene, it is max 2010 x64 and uses lock/bond for collision detection. (I dont know if that is the correct way to go about it but its what i first came up with)

Thanks :)

*edit* after a bit of tinkering I have been able to make the sparks travel at a faster pace from the crashing teapot! Animated the inheritence speed of the born particles... here is a preview of the viewport :)

It looks to me you might be overcomplicating it a bit :) I'd just create the seed particles on the teapot volume, and check the follow emitter, then I'd use a collision spawn set to 'continue' and spawning the actual spark particles, that are given speed with a 'horizontal icon out' speed op, with the pflow icon parented to the teapot, and then some gravity, ground collision and delete by a random age. I can make a sample scene later, ain't got a mouse now :)

Ah thanks for the help, when you have a moment do you mind putting a quick test together as I tried yours and I dont think it came out too well hehe. Appreciate your help buddy... hope you find a mouse :)

There you have a start of a setup :) You can take it from there - with some animation and more elaborate sourcing, you can get to a pretty decent state :)
