Here is a good tutorial on nparticals and fluids.................dave https://simplymaya.com/autodesk-maya-...=192&sub_cat=0 Hi Dave, i tried with particle emitter, everything looks good except one thing.. i.e., cloud particles flicker while catching fire to the object(cube), i keyed opacity and emission rate so that at the beginning fire might flow smoothly and cover the whole surface.. opacity works well, but fire particle flicker.. so is there any way to considerably reduce the flickering effect of particle emission..? it's not happening even after scaling the rate by speed..
