Hey guys,

I like to control the opacity of the dustpuff sprite shader with a ramp parameter which has been applied to a few particles. Something like using a ramp to control the opacity of the surface in maya.

I tried inserting a ramp parameter node inside the dustpuff shader but it doesnt seem to work properly.

Any help would be much appreciated.

Try mapping the ramp to life or age/lifespan and sending to alpha…
Best way is to send send a .hip we can modify…
