As topic, how do I make my model to have this look to it?
I intend to animate the model and the black particles should follow the model. It does not have to be animated.
Hope someone can help with me this. Thanks!
I think you may be asking the wrong question (and in the wrong section). If you intend to model this glass object in 3d and want the particles to appear (and flow/move around inside) - you are really talking about particle simulations (and possibly force fields), not materials.
Probably the best way to get the initial particles in the shape you want is to model a mesh with the rough shape of this “creature” - then make it emit particles from the mesh volume. To make the particles visible - you could instance a small cube or simple icosphere.
The material to make the particles look black will likely be trivial (i.e. a black or very dark grey diffuse material applied to whatever object you decide to instance for the particles)
This took about 2 minutes to knock up using the above method (obviously your base mesh would need to be a little more complex).
