Can someone please show me how to create wet-look wood... like in this render by Juraj Talcik.

I want a patchy effect.

I guess there is no magic trick here. Proper reflectivity maps, glossiness maps, then a lot of tweaking and you are done. :)

To drive a car, it's easy, all you just have to put it in gear and use the clutch and gas medal to go forward.

Please can you show an example of how simple it is :)
There are a few vids and examples on wet look for tarmac roads..... but nothing on wood.

My post was ironic. What I meant was that there is no easy step-by-step guide to create a perfect material like this. It will definitely require a lot of hard work. But I might try creating something similar later, why not...

That is the thing where you have to use imagination. There is no like 101 guide to atmospherics  everuone is dooing it in his way.

Speaking of wood you could try to increase contrast of a glossy map or use some hand drawn map mixed from wood RD+som sort of puddle map.

By the way, have you seen this thread? Juraj is explaining some stuff in it, he shows screenshots of material setup, and even the textures... https://corona-renderer.com/forum/index.php/topic,2018.msg15098.html#msg15098

I understand this...
I try and get one sample material of everything I need... because I always....always.... forget how I did it... weeks later.
When I spend a week in Photoshop and then go back to Max... I find I have forgotten stuff.... so I need a sample material I can tweak from.

One of the administrators posted a mat for wet tarmac with puddles... this works well for flat surfaces... but not wood.

Any help is most appreciated :)

Try something like this.
Leave reflection level alone and adjust glossiness. Water will fill all the little cracks and make the wood look more glossy.
Create a second UV channel for the wet map and link it.

I don't have time to tweak the example, but you get the idea.

Patchy effect happens in glossiness map which is quite contrasty.

Wet effect happens when the diffuse is made darker than when dry, and glossiness is higher.

I like Dubcat's setup :- ) That is bit more flexible. The mix map shouldn't be that extreme though, it should basically mix 100perc. Wet, and 50perc wet, for example.

My attempt. Textures are definitely very important here.

Try out the following for fun, works for me from time to time:
Remove all maps but diffuse and bump/normal, turn glossiness off, make the bump a touch harder and turn reflectivity to 100% with default Fresnel.

This gives a very "in your face wet" look. After that you can tone it with glossiness maps and so on. Works wonders for me especially on stone textures. Never tried it on wood though.

Also don't Google the thread title :[

It could be also added to bump slot to achive flat surfaces with watter standing on it.

Okay, I am trying your method out. I want it more patchy.... where am I going wrong?
How do I link the DIFFUSE maps like you did?

Thanks, Maru I downloaded your sample and will try it now.
