i3ds and alpha over life

[Mzigaib]

I am using particles and the i3d metacloud to create a volumetric dust trail which is working ok but I would like it to dissipate over the life of each particle I've generated the alpha attribute over life for each particle but how can I transfer it to the shader as density? Is it possible?

thanks

Anyone?

Anyone?

in your volume shader you could use a point cloud to bring in your alpha attribute from your particles and use that to mult the density

Thanks for the feedback.

I think that´s possible but I never modified a smoke shader, I´ll look in to it, I just wish that would be a simpler way to do that.

Thanks anyway.

Does anyone have another idea?

Does anyone have another idea?

what idea have you tried? Did you try the point cloud method as I think that should work, no?

or you can convert the particles to a volume (volume from attrib,etc), give it a name, and use that as a custom field to amplify the density in the shader

that way all you need to do is make an import parameter (like the one for density), and mult the density times that, or if ur using pyro, specify the user field, then make a field mod and plug that in as the amplitude mod
