Internal fractures with specular material

[sillygabe]

Hey,

I'm using voronoi fracture with dynamics to shatter an object with a specular material on it. I would like to achieve a look where the glass surface appears as one solid object with no internal refraction visible until the fracture dynamics kick in.

Basically the same effect as in this tutorial:

Any idea the best way to achieve this with Octane?

Thanks!!

Maybe put falloff node in the opacity channel? Or on a geo level, could you use those selection tags with mograph and turn off visibility with a Plane Effector with a spherical falloff field linked to the ball?

The fastest and simplest way is to just swap geometry at the first frame of the shatter. After all, that's pretty much what actually happens in real life, too; there are no fractures one moment, the next moment they exist. It should only take a minute to set up, and then you don't have to mess around with shaders, nodes, effectors or any of that stuff to make sure it looks right. I think the KISS principle applies.

Dirt texture is like AO shader. Same method should work.

Hi there,
the dirt node gets me close to what I want yea. but is there a smoother and 100 % solid way to achieve this? I want to scatter a bottle from top to bottom, so just swapping doesn't do the trick either.

Hello, does the new version also use this method to achieve this effect?
