Do you have any depth of field turned on? Are you using aux particles. If using aux particles, the default opacity setting is 50%. If dof is on, that is a natural part of the blur. If using motion blur, try turning up the opacity boost.
Hello, fausto, mike and whoever could be of assistance here.
Well, i had the same problem,
my particles are with less opacity.
There's a camera with DOF.
The Emitter is a solid but referencing a layer in 3d space.
The particles are sprites (a tiny animation)
I am using motion blur (on the layers and it's On on PARTICULAR)
I tried to use: Boots Opacity (100%), linear accuracy(100%), disregard everything... no use.... Still some mo-fo particles are tranparent.... Is there anything else i could check? or there's no solution?
If you have dof on it will make close particles transparent. Make sure you don't have dof affecting particular in the particular settings. Also turn off motion blur to see if that is creating the problem.
