I'm not very good with cinema 4d, just been teaching myself with no real instruction.
What i'm trying to make at the moment, is a blood vessel bursting and letting blood cells leak out.
Got the blood cells part working fine, just trying to figure out how to make a blood vessel split realistically.
I thought if I could make 4 individual groups of polygons bend outwards making it look like its burst. I know how to disconnect polygons or split them from the main object, but how do I attach just one edge again to the main body and then make it bend only on the disconnected part?
You can connect objects weld point using weldtool (hotkey M+Q). What you want is to hand animate each point. It will be easier to use morph tag if you have it.
You can also use cloth or a plugin like xbreaker depending on the structure of the cell.
