Hi - at the end of this exercise, Kent quickly demos putting in a single map node at the beginning of the shader chain to tweak the noise textures positioning. He then mutes it and goes on to demonstrate the constant color(ramp) version. If I do not mute this map node and indeed tweak the position while also using constant color in the ramp - I just see solid colors in my render and no pattern anymore. Can anybody explain why that happens?
Update - everything seems to work better if I use Object coordinates instead of generated coordinates. However, I note that Kent does use generated coordinates. Any ideas why I have to use Object coordinates?
Hi Eric,
Where Generated Coordinates go from 0 to 1, Object Coordinates go from -1 to 1, which means, that when using Object Coordinates, you get more texture (and the texture will look smaller). The same effect you get by doubling the Scale (and moving the texture -1 in X, Y and Z).
So, by using Object Coordinates and thus showing more texture, you also got more variation (in the Texture Output) and the 'chances' of getting to different 'sides' of the Color Ramp with (I assume you mean) Constant Interpolation (not a constant Color) have also gotten better...something like that...
