How to get a gritty gel texture (Toothpaste)

[CNSMedia]

Any pointers on how i can layer up a material node to get this effect of a translucent gel with opaque gritty bits inside?

TIA for your help

That’s simply a principled shader with a bit of height variation & a few particles inside.

The toothpaste itself looks fairly simple - a basic blue glass shader with perhaps a little volumetric scatter or translucency should do the trick.

If you want a purely shader based solution for the particles, you could use a volume scatter/absorption material driven by a voronoi texture. Kinda like what I have done here - but smaller scale (the volumetric SSS material is on blendswap if you want to download it).

Volumetric SSS

Yep kinda - although random walk is still an approximation and suffers from it’s own little niggles. This nodegroup includes more options and tunability. Random walk also doesn’t contain scattering anisotropy, which this node group does. Plus - I don’t think you can add true volumetric effects like this using SSS. [image]

Alternatively, you could use a particle system to scatter randomly sized particles throughout your toothpaste gel mesh.

Thanks for the info! I’ll give it a go!

I did find this example but I’m having a hard time trying to make it translucent.

I’ll give your method a go and report back
