Problem Vray displacement

berio · 8 May 2012, 07:02

Good morning everyone, first of all I apologize for my English, I have a problem with vray displacement, the material can be seen in the preview correctly, but when applied displacement disappears remains completely flat.
I tried doing a simple test in a vacuum of SU drawing I drew a face, I applied the material, started without setting the render lighting, background and the image is correct (test 1) then I added a simple object I started render the displacement but disappeared and the texture is connected (test 2).
I have tried using different materials with different textures, but the result is always the same.
Why does this happen?
Using SU8 + Vray 1.49
I tried looking for answers in the forum but I've found.
Someone happened to this thing?
Thank you.

First question is your geometry a group?

I don't use Vray, but I have read other posts out of curiosity, and from that I would ask if you have your water plane set above the Vray infinite plane.

Thanks for the answers
For Bhbarchitects, no it is part of a group (I had already read of problems with the groups).
For Mitcorb, the water level is placed above the infinite plane of SU.
I'm going crazy for this thing.

have you got the .skp so i can have a look

As soon as I can post it thanks BHB

Please read through this topic first. Your object needs to be a separate group or component for displacement to work.

Thanks andybot, I understood the opposite, damn google translator and cursed me that I do not know English, retry the test tonight, thanks again.

How about sharing that water material with the group?

berio · 9 May 2012, 12:32

Fixed, thank you all.
If interested I attach the material

Mare nostrum.vismat

i'm glad that your problems got resolved, and i need to say that is one fine looking water!

since you already shared the material, would you be so kind and post the displacement texture as well?

this is good vismat. mind sharing the displacement bitmat too bro?

thomthom, did you manage to get the displacement and/or the diffuse texture out of that material?

I'm on vacation, travling at the moment. I'm currently just checking in on the forum from time to time. So - no, because I haven't tried.

Good morning i m using Vray latest version and Sketchup 8 pro
I would like to ask that i am doing the same sea like yours and to my understanding the sea water have to be a bit transparent but since the layer below my sea square are totally empty. It looked ridiculous when light penetrates the layer of sea displacement. So how do you guys set it to be like the image above. I have the displacement Mapping but i am just curious about the reflection and colour and transparent setting.

I make a black box or plane under the water.

Thanks ThomThom the result is just marvelous

Hello everyone
This topic here is a bit older, but I have exactly the same problem.
First .. sorry, my english isnt the best
Using Sketchup8 and Vray newest version.

I'm trying to create a photorealistic carpet (Lambswool) as well as a stone wall inside a building. Usually it works fine, but not this time. So note .. everything is seperated grouped, that shouldnt cause my problem. I was trying to render my scene to see how the displacement works. (using displacement and bumpmap for my carpet). But when I render, the carpet material still looks flat, nothing to see of displacement. Really my first thought was 'its not grouped' .. but it is. So the problem must come from another wrong setting I did or so.
I'm wondering that I cant set any multiplier on my displacement map. Where is this button?? It should be right below the texbitmap button, but look at my screenshot ..theres no multiplier.

Tried to play with the displacement settings after it didnt work, but cant get it to work.
Displacement settings:#
8 (tried up to 80)
Max sub: 256
Edge L.: 4,0
So changed values several times in order to get it work finally. But nothing happened. Carpet still looks flat and does not show any of displacement. Rendering takes long, but I know it has to when I use displacement, so thats not the point.
I really guess the multiplier causes my problem. But how to change multiplier value when theres no button for? Or is it hidden somewhere else in the new version of Vray so I just didnt find it yet?

Thanks guys, hope you can help me to fix this .. I dont get it to work since 2 days - 2days/ 12hrs per only busy with one problem and dont get my work done

best wishes!
