AntoniaTiger, I agree about the manual. What I know about how those three scale inputs work, I only know because Stewer told me. Basically, the turbulence node is a fractal function that produces a number between 0 and 1 for each point in 3D space. You could write it like this: f(sx, sy, sz) where s is a scaling constant hidden from the view of the user. If you don't have anything feeding into the inputs for the scale parameters, then each coordinate value is multiplied by the scale shown in the respective parameter before the function is evaluated. For example if you have xscale=2, yscale=3, zscale=4 then the function will look like this: f(2sx, 3sy, 4sz) If you feed something into those scale parameters, it replaces the x, y or z value, so you get F(2inputA, 3inputB, 4inputC) (The 2, 3 and 4 are there because Im assuming we leave those three scale parameters set to those values. Notice the s disappears once you connect an input) If those inputs are constant values, such as the output of a simple color node, then the output of the turbulence node becomes a constant value i.e. its just one shade of grey across the whole of 3D space. If you only feed a constant value into one of the three inputs, then you only create uniformity in along that axis. For example, if you want turbulence that varies across the ground plane, but looks exactly the same no matter what height you are at, you could feed a constant value into the yscale input and get a function like this: F(2sx, 3inputB, 4sz) Mizrael, The node setup you are copying comes from Poser 5 and the one youve posted is from Poser 6, so thats why your preview looks different for that shader. Regarding the shader I posted, Im pretty sure the reason your preview window looks different to mine is just what unit Poser is set to use. 0.0009 feet is a lot smaller than 0.0009 NPUs. You could always try just turning up the displacement setting until you get a similar look in the preview.
