how to approach making these granules? Ok, so I have to make this product in 3D, Im fine with modeling and texturing the container, what Im not sure of is how to approach the granules inside the container, its almost like a rough sand/ gravel look and feel only its white... any ideas on how to approach this? 

Thank you in advance :)
So I found another way to approach this. Using the particle system in blender and using the hair type, I just sampled a granule that I made quickly and emitted it over an object which would have the same shape of the granule inside the bottle.



As you can see in the image, this seem like a decent approach, I still have to play around with the settings and the texture of the granule but i think it will get the job done nicely :)
