How to create Flakes Material in Corona

[ranabarzam]

Is this kind of material possible in Corona? I have seen a tutorial in Arnold but I don't know how to create this is Corona. Will really appreciate your help.

Hi, thanks for the reply. The thread you have mentioned is focused more on car paint or surface multitexture. What I am looking for is something like the link below.

As you can see in the video flakes show up inside, for Keyshot. But is there any ways to do so in Corona, like if I want to create bubbles inside a liquid or something like that.

How about these?

One great solution is placing a camera above a plane and scattering some random objects on that plane. Then rendering this as a normal map and using it to define the direction the flakes are reflecting light in.

Corona does not have a volume flakes shader that I am aware of. You would need to scatter many small planes to the interior of the volume of the model you want to have this effect rendered with, i.e. you cannot do this entirely with a shader in Corona.

I'd prefer that in any case for the given example, much more options. Nothing beats geometry.


Good Luck
