Scattering droplets will have a different feel as the sweaty condensation type Caspian is after. I've only did this on glass where I simply put a condensation normals map in the bump slot of the material that I've used on outside of the bottle. I've tried to make a copy of the outside mesh of the bottle and have a separate water material with a normal map for the condensation and alpha for transparancy but that gave a lot of artefacts. Deadlines were quite close, so I had to fake it till I made it :)

It would be a lot better to have the condensation and glass separate though, so I'm curious in this solution too..

Redeemer, am I understanding right that in your render I'm looking at bumpy glass/label, and not water on the glass? The reflections don't seem right if it was if it was water.

Almost all of the Mograph tuts I've seen (like the popular GSG one) using scatters, randoms and falloffs make it look as if the droplets have been sprayed/stuck on and not the more convincing water effects I was achieving in my example at the top of the post using Physical Render (as if a bottle was taken out of the fridge and had a little time to warm up). I'm going to keep experimenting, but bare in mind I'm probably the least experienced person in this thread  :)

Thanks for all your advice so far.

---UPDATE -- I might have to invest in something like Spritz if I can't solve it before I go mad.

Thanks for the advice but neither of those tips produces what i was hoping for. I added an alpha…
Left: layered material | Right: stacked but with alpha.
I mush be missing something so obvious. I realise that this is still in beta and there are no official documents. I just wish I knew how to solve it.
The native c4d stacking allows materials to interact, which was why I (wrongly) assumed it would be similar.

Forgive my basic knowledge of how Coronal handles materials but I must be missing something very obvious.
With a simple scene and a coloured cylinder, adding the water texture seems to be removing the coloured material below rather than adding to it.
My file is here if you want to see what I have done in more detail

Many thanks

Thanks for the tips – now I see where the normal is hiding! Ha. I'll have another go this afternoon. And thanks for the Link to those textures.
Cheers

I'm not having much luck working this out. Should I be trying to create a layered material? I'm trying it this way for now but its looking pretty ropey. I'm using the same noise setup as my previous glass, so it should have a lot more droplets on the surface. I've also not worked out how to add a normal channel. I've found lots of tutorials out there for other apps but not many for corona materials +C4D. Am I going about this wrong?
Thanks!


-- update -- just watched a YT that confirms that material stacking is OK... but I still can't get a decent material out. :(

Thank you! I haven't explored the material node system yet. I guess I ought to roll up my sleeves and give it a go.

I'm relatively new to Corona and doing my best to work out how to do things differently (and why) to just bing in C4D. One thing I was trying to achieve on the weekend is replicate the condensation on a surface. In C4D I do it the way 3D Fluff taught me: using a number of noise shaders in the Normal and Displacement channels of the material. Corona materials don't have Normals, but it can be achieved in C4D with the Bump instead. Does anything have any bright ideas how this can be built with Corona? My attempt to replicate it didn't show up one the interactive renderer even using a corona water texture. Any help gratefully received. Thanks
