Thanks for pointing that out, I've fixed it in my post.

Nice site Andy. And clean tutorial. Done any work with Nelson Byrd Wolf? They are doing some landscape architectures in a couple of our projects.

hi, i had this problem in displacement, whenever im trying to render curves, it comes out segmented

look at the yellow pillow

Something useful to consider when creating a displacement map, courtesy of http://viscorbel.com/vray-materials-theory/#comment-6946

"The deformations work like this – middle grey [128;128;128] of the map does not change anything on the object, darker values push the surface inwards while lighter values pull it out. The further this value is from medium gray, the stronger is the effect. Color of the map is not taken into account and only the lightness value is used."

This is good to know when you don't want the geometry created by the displacement to extend beyond the modelling you've laid out... eg bricks protruding though picture frames hanging on the wall

I switched the displacement multiplier up to 50, but it doesn't change a thing.
I created a grey rectangle outside my model to check if it would work there (so it isn't connected to another material).. still the same?
Can someone check my sketchup file? Really stuck here. As far as I know I'm not using any groups for the model, maybe by accidence a while ago (been working on it for quite some time now..).

(if you open it, does it look like a heavy file? Sketchup blocks from time to time for a minute or 2..)

Thank you!

When sharing files, remember to use the "Pack Scene" tool in V-Rays tools. You can find it by going Plugins>V-Ray>Pack Scene. This will ensure your scene has all required materials and textures. The scene you shared does not have the associated displacement map you are using so I cant accurately test or check anything.

Also, download and try out the grass file I've attached.
