I tried to load a particle emitter from 2.49 to 2.53. It emits sparkles that individually go from white to yellow then red throughout their life. The halo colours are changing over the frames 0 to 100 with keyframes. It works perfectly in 2.49.
When I load it in 2.5, all the particles change colours altogether from frame 0 to 100 then nothing, I mean they are all white in the beginning, than all yellow, then all red…then all black !
What is changed in 2.5 ? How can I achieve what I want ? Has that 100 frames material for halo disappeared ?
Many thanks in advance
