HOW i CAN MAKE REAL WATER IN VRAY

thomthom

The color: reduce the Color Multiplier for the fog to reduce the density of the colour.

Texture: Just search for "water bumpmap" and you'll find loads.

Your test model: you only have the water material in your scene - everything else is pure white. Add some materials to the other geometry in your model, that way it'll look better - your reflection will pick that up. Also, avoid using pure white as it can throw off V-Ray's calculations some times.

You are awesome, I will post my results and maybe a tutorial for all if I have time.

Thanks.

I what part I can ad the bump map to create the ripples effect? I found a map that I can use but i am a little lost..

thomthom

Found an old test scene on my hard-drive.

Note that the way I mapped the bumpmap in this model is not how I'd recommend it to people who are new to VfSU. I'd instead use a dummy texture in the diffuse. (which won't be visible any way because you make it fully transparent anyway.) then you can easily control the UV mapping by using SketchUp's texture tools.

Please, when postings - do not use all caps. It's bad forum manners - seems like you are shouting. If you do not care about capitalisation, then at least use lower caps.

For water materials I just use a 100% diffuse layers and a reflection layer with a Fresnel map. To get the ripples you add a bump map.

If you post a picture of what you have, that would help to give more specific tips.
Remember that lighting and the environment reflected in the reflection will affect how realistic the water looks.

Iam sorry Mr thom but I like this render it is not posting to them but I want to say how I can to did it
thnx to to your advice I will make my render and give me your advice

Hello:

I try the settings that I read in the web in some tutorial but I have no luck what so ever in the final render. I learn Caustic now but I want the same results as the render final I will ad later caustic. I just want to see the same bumps that I missing. Also the color is not right for some reason. VR 1.48.89 Sketchup 8 Pro, Windows 7 - 64.

I post the model and some samples for help.

Water render final (I try to get this effect)

I have this render

How I can ad bump map for ripples where I can find a map for ripples?

I hope you can help me with the settings Thomthom...Thanks.

Got it...After 6 hours of learn caustic and try make this water render...

Ah, you wanted caustics. Did you do that with just the V-Ray sun? OR did you use a different light source?

kalu

I use Vray sun, It take me 6 hours to learn the caustic and put so many options that I am proud of the results. After I make the same results that I wanted and the begin of my question, I move in to the caustic so I can more realistic view of the pool. Now I can do the pool and the sea...Great work, but allot of learn...

Thank you ThomThom for always great help!.

I think you did most of it - I've never really used Caustics much. I'd probably have to ask you about it.

mr kalu
can you explain us pls how did you get that result ? , maybe screens of parameters ?^^

kalu

I am out of the country for vacation, I will post a result after I back in a month.

yeh - that's great - found it after looking for a while. Think i dled the model from the ASGVIS site to follow along but that went down:( wonder if Chaos Group is going to fix the forum and all the materials and tutorial links would have dled a lot more had i known:(
