pretty fast displacement from a plane.

Awesome grass -- and was that vector displacement or pretessellated (and what subdivision)?

Best,
Jason.

[rusteberg]

it's pretessellated using a vector map. don't remember what sub d was. probably default 16?

A single material on the unaltered "stage2" preview scene:

AWW ! nice Brian !

I assume it is just mxm ... not +geometry inside ?

You are correct! Single geometry (unaltered from the preview scene), single MXM, no displacement.

Negative Nd dielectric was my assumption... but there looks like there also something else unusual at play as well.

Best,

[mgroeteke]

my 'cover' version of what you are doing... this will not work with the other preview scenes, as it dependant on placed clip masks
curious about your solution...

[Bubbaloo]

I came upon the effect completely by accident experimenting with "metamaterials". Nice try Markus, but it doesn't depend on clipmaps. I'm going to see how it animates tomorrow.

what a teaser

[devista]

Very nice. I am waiting to know which is the solution of it

Metamaterials? What's that?

[Bubbaloo]

Ok, I'm not going to take the time to animate, so I'll post the MXM.

I found that if you have a dielectric with nd < 1 and add SSS, you will see only the SSS component in the refraction. Strange stuff...

nice riddle Brian , my hat is off my head, great and funny find.

now I regret that I uninstaled maxwellrender to not to fed my procrastination. I could check if this metamaterial is possible in 1.7.1 too
