Yes, I am preparing two videos, one about Daylight, the other about materials. Although I would love to make the second one when Corona gets rid of the glossiness curve, which makes any "rules" wrong :- (
today we started working on it

What... you started working on Glossiness curve or vid tuts?

Dubcat... I experimented with your technique and Maru's Noise Map and Frankensteined his with yours to produce something I was happy with.
I still don't know what's going on.... but it pointed me in the right direction. Thanks.

Unless you're trying to recreate puddles on the wood, you need to map glossiness and bump on wet material as well. Just make sure that wet material has a little bit darker diffuse and a little bit brighter glossiness. I did quick and lazy setup to show what i'm talking about. Of course, it's better to control maps by color correctional nodes or by modifying texture externally, instead of changing map's amount like i did.

Thanks for the reply.... and the info.
Really helps the scene (alot) when you have a wet look. I noticed you posted a wet tarmac sample.... which is useful.

What I want to master next is vertical wood or concrete. Where the rain has wet the top of a structure, while the bottom is dry. Any tips on this problem...?

well, the 'artist' I think is a category, there is no other. I never call myself that, or actually anything. I just do stuff.

It's not as easy as people think though, I have lot of work daily, family I have to help and visit, and to create 1 hour of video, takes about 20 hours of preparation. Or even to start.... which is why I am much better teacher "real-time", where I can just talk,
then organizing myself to do proper job.
I answer tons of stuff people ask me, that is very easy compared to it. Everything else stresses me quite a lot, and I am in lot of stress already in life.

Just to cheer you up.... your work is the benchmark for me that I compare myself to.... and that inspires me.
I study it in detail.... and ask myself...."How the damn did he do that?" Which pushes me to improve further.

Someone wise once told me that as you get older... you want to be paid more more for doing less.... because the info and experience
you have accumulated over the years will be very valuable. So I am sure one day.... all this hard work will reap rewards :)

I am really happy you are doing video tuts :)))
Sometimes just the smallest piece of knowledge can make big differences... especially to your confidence. CG is not easy. It's one of the hardest things I have tried to learn.
While Corona has really helped the industry... there are still too much to consider to get good results.

Even a DVD that you could post or offer for download (for money) would cover the time and care to produce it.
And I am sure it would be popular.

Alex Hogrefe started doing a free site for Photoshop architecture illustration techniques many years ago based on his student portfolio. Now he lectures all over the place at colleges and has produced several books for sale.

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.

Are you ever going to do a 101 Basics of CG vid.....people have been banging on for years about..... or has that bird flown the nest?

When it comes to understanding stuff... a YouTube vid (with voiceover) is so much better than anything written.
While Corona has done many "How to" vids.... they don't really talk about CG as an art-form. And I see on your Facebook page you title yourself as an "Artist".... not a designer.

Change IOR in the wet material to 999.
Throw a Color Correction on the wet mask and adjust until you get the effect you want.
Change the IOR back to 1.33 when you are done.

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

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

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.





Many thanks, Dubcat :)

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?

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...

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 :)

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.

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

I want a patchy effect.

My process is Sketchup.... 3Ds Max.... Corona.... Photoshop.

For me.... the most frustrating part is the final stage because for all the effort I have put in.... I am never satisfied with the end result.... there are just too many processes to fuck up.

What I feel would be very successful is expanding Corona to have a COMPOSITING plugin that can work in 32bit exr and save in 8bit JPG.
The software out there (like Nuke) is complex and expensive.

Corona have simplified and made rendering 'a thing of beauty'.... I just wish you guys could apply the same formula to the final (most crucial phase) PRESENTATION.

With both Adobe and Autodesk going to the cloud.... a bold (and somewhat sinister) move to take ownership of creativity.... there is a new opportunity for software companies to produce
software that is stripped of bling and just does the job.... simple and straightforward....I just hope that C4D stays strong and does not go to the cloud.... coz everything I have read suggests
alot of Max users are going to jump ship to C4D....there is a huge fan base for C4D MAC uses to.

If Corona could do a Photoshop style compositor... that would be great.

It's like STEAM and gaming. In the good old days... when you could buy a game...install it and play....now you have to go through STEAM... and it's a big turn-off. I have stop playing games as a result.
Everyone is trying to control the market... which NEVER benefits the guy on the street.

I have asked permission from alot of photographers I have used in the past for doing paintings.... they are always flattered.
This one time I did not ask permission.... and it backfired.

I sent her this video (you are probably aware of) about intellectual property.... part 4 of 4.


BTW - Your up late.... are you on 'render watch'?
