Particle age

Hi. Is anyone familiar how to control particle age similar to cycles? Thanks.

Could you please explain in more details what exactly you would like to achieve?
V-Ray for Blender currently doesn’t support Particle Age.

i want them change color with time so when they getting older color is changing. I found sampler node (im trying to use it with remap node) which has a lot of outputs but no documentation which output is doing what. One of the outputs self explanatory like velocity (which is working fine) but i found between them “Frame time” output which could be instead of “age” but no luck. PS. Motion blur working with particles only some times. Basically it works 2 times out of 5, And what about Particle texture and Point particle?

Hey can you please upload a scene where the motion blur doesn’t work?
