First tests of my dust particle generator…

I really like this dust! It looks very natural. I’m guessing geometry nodes? Is the fine layer of dust individual instances, or is it done inside the material?
Hi @sidp ,
sorry for the late reply. I posted the images just before going to bed.
Indeed, I used the geometry nodes to create and position small filaments on the top of the objects and the rest is managed by a material.
It was an interesting first exercise in discovering these geometry nodes 
I still need to figure out how to apply the material for the fine layer of dust on all the objects in the collection that receive the little filaments…

Masking using the Z component of normal is quite practical, but it doesn’t prevent dust from being applied deep into the cavities (which I don’t necessarily want).
I don’t have this problem with the fibres because they’re placed differently: Raycast - backface - #3 by picto
Still using an image for the dust in these tests. I’m now going to try replacing it with a set of procedural textures.

Just a cool shape I saw online.
I think the original is from here.
An interesting modelling exercise that I invite you to try.

Amazing work!
Just a quick question
How did you post these panning images? what’s the syntax for this?
You simply need to clic that star icon in the editor menu and then drag and drop 2 images inside the generated code.
<div data-image-comparison-slider data-direction-horizontal>
Add two images here. Change 'data-direction-horizontal' to 'data-direction-vertical' for a vertical slider.
</div>

Very nice 
. Good job!
Toothbrush?

Without the brush for the moment, but yes.

You pulled it off very well though!

Looking good, but I would suggest some transparency on the orange juice.
I did try to make the material more transparent depending on the thickness… but without success.
They are already a mixture of SSS, transparency and volume shader. Maybe it’s too complex or even contradictory 
Any tips on how to do this?
If you live in the European Union, does this mean anything to you?
The idea was to test LiquiGen… which turned out to be a complete failure. In the end I managed to get something decent with a simulation in Blender.

Cool idea, looks nice, and the trick is to put the lid to the other side, which is funnily possible and a real solution to the problem.
Yes, but sometimes the lid folds back.
It usually happens early in the morning on days when you’re already late…
