MATHS NODE: MAX

The Max maths function compared Value_1 and Value_2 and outputs the higher of the two values. This often has the result of merging the two inputs, as seen in figure 1.

This could be seen as a logical 'OR' function. If either Value_1 is high or Value_2 is high, then the output will be high.

The max function can also be used with a single input node, using the second Value to control the result. The result of this is to filter out the darker elements of the input node. The higher the second value is, the more elements will be filtered out. Figure Two shows the result of doing this with a Turbulence node plugged intoValue_1 and Value_2 set to 0.3. The result of this is to filter out the darker parts of the Turbulence, replacing them with your value_2.

Suggested Uses:

Try using a U or V node as value_2 with any othe rnode type to produce an interesting effect.

Try plugging any two of Turbulance, fBm or fractal_sum in to a max function, to combine them and provide more variety.

Try using a max node to combine two specular lighting effects on a single object.
