Work Flow: V-ray for Sketchup
Here is a quick tutorial to show how you can achieve realistic carpet material by using V-ray for Sketch-up 1.49.01. All you are going to do is add a displacement effect to the surface so that we can improve the details of the surface in the final render.
For this excercise, I recommend you use a surface with round edges and smooth bumpy surface, instead of a flat and squarish, so you can get a better look and realistic feel.
LETS GET STARTED!
1. First Step is to create a default material
On your material editor under the "Maps" category, Check the Displacement box so you can enable the displacement options for this material. Next, click on the M beside your displacement to open the texture editor.
Here is your Texture Editor.
- Select "Texsplat" from the drop down menu (produces a texture with white dots
on a black background)
- Change your iterations to 10 (to increase the repetition of the texture)
- Change your size to .005 (to decrease the size of the white dots on the texture)
Click preview if your satisfied, or change the settings more to your liking. Click OK
4. Back to your mapping options
- Increase your displacement multiplier to 3 (or more) to increase the height of the
-Uncheck "use Globals" to keep the displacement settings to this material only.
-Change the "Edge Length" to one, this setting controls how thin your carpet strings will
be, the lower the value, the thinner the string.
This is how your material preview should look like, and when you apply it to your surface, it should look something like the image below. Remember, instead of a white diffuse color you can also add your texture mapping so you can get a different look, with that said the possibilities of what you can create are endless.
TIPS TO REMEMBER
1. Use a more defined geometry shape, one with smooth curvy edges and bumpy surface.
2. Play with you "edge length" and "displacement" values.
Thanks for reading this tutorial, and i hope it helps you in creating your realistic scenes. I'm learning vray just like everyone else and just want to share what i learned. :)
