Alpha Scaling

Normally, if you drive a component's value with a texture, the texture's alpha channel will set the value without regard to the amount that was set using the component's slider. With Alpha Scaling turned on, the amount set with the slider will "scale" the amount provided by the texture's alpha channel. This gives you more subtle control over the influence of the texture on the material component's value.

Alpha Scaling works with Diffusion, Ambience, Specularity, Metallicity, Transparency, and Reflection. It has no effect on Bump Height since bump is not driven by alpha channels.

The image below shows Diffusion set at 25, 50, and 75, with the second row using Alpha Scaling. Notice how the top row doesn't show any difference in diffusion without Alpha Scaling selected.
