I just started out learning Vray for Sketchup. I am trying to create a texture with a displacement map. No matter what setting I try adjusting, the texture still appears flat. I've played with the multiplier setting, adjusting it from high numbers to low numbers. I have also adjusted the displacement settings under vray options. Nothing seems to work.
i've gone through hell trying to figure out displacement maps. not sure if this is the same problem your having but... every material needs to be in its own group/componant. if there are two materials together on one entity the material will render flat. good luck... let me know if you figure out anything further.
Bless you dude. I've spent 7 days trying to figure out displacement maps... I couldn't get anything to work.... I just had to assign the same material to the rest of the faces of my object like you said. Thanks!
Although, I think that kind of sucks that I can have more than one material per object and assign displacements. This means I'll have to model oddly to get the results I want. Such as cutting faces from geometry to have them floating as pieces to assign more than one material w/displacement.
2- I would be very cautious of your subdiv and edge length settings. If doing something hi res try using subdiv of 75 and edge length of 20 first. I find the default of 256/1 can really kill processing times
why does my vray render have such poor quality? I have turned the denoiser on
Its still very blurry
If anyone has any suggestions please help
Also how can I change the sky?
Im not sure why it does not seem to work

You seem to render to quite a low resolution, depending on what the rendered image is going to be used for. On paper that would give an about 1,5 x 2,5 inches thumbnail image (at 300 DPI)
I would perhaps increase resolution and, for speed, turn down the quality to Medium, as the Denoiser is on.
Hi,
I am new to using Vray Rendering within Sketchup and am having difficulty getting all of my imported images to render. They all show up fine in the sketchup view, but most turn white in the vray-vision view.
Any help would be appreciated!

The light looks very different from SKP to the render. Are you trying to use the SKP sun in vray? Or is that somehow how you got the SKP shadows where you want them, by manipulating the sun in the vray light panel?
Can you share a screenshot of the materials browser with the light panel on? I found on a recent render I had multiple light domes that were active that got copied in from another file. Was really messing with the mood.
It seems that the shadow you see in SKP is very different from what you see in vray - the SKP light and shadow looks like an early morning or late afternoon light, where in vray it is coming from nearly above or perhaps the other side of the room and what you are seeing is really the ambient light creating the reflection.
When I setup scenes like this (just finished a bunch of exteriors and interiors) I will review that lighting by using the material override feature on the settings panel. I will keep the glass as glass but override all the other textures and materials so I can just see the light coming in (saves time, and lets you focus on the light and shadow).
I also use the vray lightgen tool. Setup my view, run light gen locally (I do all final renders in chaos cloud) go get a cup of coffee and then review them when I get back - then pick the best one for the scene and tweak as needed.
