Very cool.  Could you break down in more detail how to setup the metaball/ magnet force?

@jinomian01: ul.to / 4ar9nd2p" <-- Here's the HIP file. C&P into your browser's address bar, and remove the blanks. Easier to understand if you look for yourself ;)

Sorry I again have a question!,but be sure this is the last one!, how did you assign a shader for inside of fractured object?

[dr4ziw]

@AmirMansour: Easy! ;) Once the RBD object breaks a lot of groups are being created. the important ones for assigning shaders here are "OUTSIDE" and "INSIDE" which can be used by the material sop. Might be necessary to assign the outside shader at object level, as well.

Perfect!

I have a question - is it "Make Breakeble" dop ? How did you UV map geometry inside fractures?

[dr4ziw]

@Shiva4D: Yes, it is. But there's no UV mapping involved. However, you could try to UVproject onto the "inside" group. But I'm just guessing, right now.

@dr4ziw

Thanks @dr4ziw . This helps alot.

@dr4ziw :Owch i really didnt understand where to change the material for Outsides and Insides! Thanks btw:)

[AmirMansour]

sorry now i read the comments! no need to answer! thank you:)

[AmirMansour]

i have almost the same question,first how did you used shader for the material inside of the broken objects?, and second is it using metaballs magnet force? because it looks like explosion from inside of the geometry, Thanks again!
