Displacement settings

[zun_kian]

Hi! OK I'm totally a newbie and have an issue I want to resolve.
I want to use displacement on a large area but it seems VRay cannot scale displacements for large areas.
I have done two renders one is a .020 m X .020 m plane and another of a .200 m X .200 m plane. They both have the same displacement texture (bitmap) and the same settings (multiplier at 0.03) The displacement texture on the .020 X .020 is perfect but the displacement on the .200 X .200 is very small and barely seen.
Can anyone tell me what am I doing wrong?

PS. Upload folder is full so cannot load my rendered images to show comparison.

Re: Displacement settings

It is hard to say without seeing the renders. Attaching images is disabled on our forum (the message just says the upload folder is full). Just put the images on imageshack.com or photobucket.com and then link it up here on the forum. That way we can have a better idea of what you're trying to describe

The images are uploaded on Photobucket
Here is the URL:

Please take a look and let me know what to do.

am glad to help..
here's zun's images..

i think you got the texture too small, that it looks good at 0.02x0.02,
try scaling it larger..Material window > edit > size = larger maybe 1 or 2.
then render.

i hope it work.goodluck!

Re: Displacement settings

Thanx migz
What I did with the renders shown is I used a displacement map image or texture in VRay Material Editor. There is no image texture on the planes. But nowhere in the VRay material editor you can scale the displacement map.
But in other cases, do you mean to say scale the image textures in SketchUp first so when you place a displacement map or texture in VRay it will automatically re-size itself as to the size of the image texture?
Enlighten me on this matter please.

Re: Displacement settings

yup, start scaling texture in sketchup,
vray will adapt on sketchup's mapping..
good luck.
