particles alpha

Recommended Posts


So I applied basic principledshader for my particles. I tried different settings for opacity (fake caustics) and transparency. But those does not affect anything on alpha channel, only RGB. I can scale down pscale, but I dont want that. So how can I make the particles be less visible (alpha channel) but not changing pscale?

Add a wrangle or a vop at the end of ur network.

Wrangle setup >>> @Alpha = fit01(rand(@ptnum),0,1);

The shader will read this attribute.

Change the 0 is the min alpha and the 1 is the max, mess with those values to get the result you want.
