Hi,

in Clarisse, how would you tackle a task like adding a dust layer onto a bottle? With a texture or maybe a point cloud/scatterer?
Here's a link to an example image:

Thanks for any tips,

There are lots of ways, bust most would involve blending 2 shaders, one for the clean glass, then another for the dirty VERY unglass like dust surface.

Then on top of that if you wanted to get a bit crazy and scatter a million little "dust bunnies" around nobody would stop you!

Thank you very much! Sounds pretty straight forward and I think I should have been able to figure that out myself

I found this a fun little thing to do, so here is a good place for you to get started

It's 2 separate shaders, clean bottle and dirty bottle. Then I am mixing them together on a Multiblend using the same "fingerprints" map i'm using everywhere else. The label also has some stretched out fractal to look like maybe someone tried to wipe it


Here is the graph, you can see how the finger print texture is driving everything, including the blend between the 2 shaders. The finger print texture is always going into a gradient, so that I can manage the levels to get the results I am looking for and each channel can be adjusted independantly a bit. Reflection, Specular, Blends, Mixes, Transparency...etc. My finger print material is also a Triangular projection simply because I usually work like this so I don't need UVs to apply these types of materials to objects.


Here is the project with the textures applied to a sphere, so you can get the scale of the bottle I used. Just scale the texture projections to fit your object.

Wow. That's definitely super helpful. Thanks again!!!
