I think you should try to create one really small geo inside your main geo and increasse collision width to cover up the space inside the main geo..
hope that works.

hi Aikiman,

i got to see your file at work today.
is it possible to turn on the particles that are completely iinside the geometry?
do i have to fill the geometry with particles and make them collide or something?
i'm out of idea.

They should all be on, thats the reds ones inside the geo also. It might just be hard to see because of the gray particles opacity is set to something low. If you take a look at the particle expressions you can see how I control the color and opacity. The opacity is controlled with outWeightPP from the attributeTransfer so you an take a look at the bounding objects weight ramp and adjust that there if you like. If you are unsure you can increase the scatter node points density but I thought I had all of them covered.

Hope that answers your question.

setting 'Scatter Mode' on scatterShape1 node to 'Both' solved the issue.
thanks Aikiman.

btw, does nParticle collision test only work for the surface of a geometry?
can they collide with the volume?

Nice one. nPArticle collisions dont consider internal volume, its just based on verts/faces.

Control particle display with animated mesh

Hope this tutorial will help you for creating the LED effect.
