Hi Zeger,

I want to try out your textures, but they are macros. I created a box and 
added "texture { MetaalBol(1) }", which gives the error message
"No mathing } in 'texture', texture found instead".

How should I use the textures?

Greetings,

Sven

thank you :)

that's more or less the intention :)

sure, see attachment

use as follows:

#declare Seed=seed(123); //seed-value for random translation of the texture
#declare BS=1; //Bump size of the texture
object {MyObject Metaal()}

it can't, I had to turn off the normals or it just looked weird :(

hmm, I don't know...
it's hard to subdivide a superellipsoid in another way :-/
