Mapping Textures 3ds max Controlling material sample size Let's drag over a Noise 3D. So I'll drag Noise 3D over and drop it onto the input for the base color map on that physical material. When I release the mouse, I get a pop-up asking, do I want to connect the output or one of the X, Y, or Z outputs? So we have multiple outputs on these OSL maps. I'm going to choose X and that's a simple grayscale. If I had connected the output it would have been a sort of prismatic effect. If I click on the OSL map and my preview is showing the current selection then we can see that it's three different red, green, and blue noises superimposed. And I'm just taking the first channel of that and using it as a grayscale. Now the question comes up, what is the size of this sample? If I go back over to the Material node, it'll update. We really don't have any idea of what the scale of this is and we actually can't even check that or change it in the Slate Material Editor.
