Help Changing Granular blueprint meshes and textures

[Rearden]

Hey there! I tried to find an answer at FAQ but with no luck, unfortunately.

Could you please help me with my question - Is there any way how I can change apperience of particles from granular blueprint?

So for example, I want to change default sphere for a box or a custom mesh. Also, it will be great if I could change not only mesh, but textures as well in addition to a particle color.

Thanks in advance!
