Blending affects how the layer is placed on the previous ones. |
The mix amount defines how much the layer is blended in. A value of 0 makes the layer invisible, while 1 makes it opaque.
The blend mode defines how the two layers are blended. Given the RGBA values of both layers, what formula does it use to create the end result.
![]() Just uses standard alpha blending. |
![]() Adds the two colors together. |
![]() Subtracts the new color from the previous color. |
![]() Multiplies the two colors together. |
![]() Divides the previous color by the new color. Note: Divide can be a bit unruly due to things like dividing by 0. Anything divided by black is a NaN, which different computers handle differently, so watch out! - A common fix is to either add an Math/Add effect, or a Math/Clamp effect to avoid 0s. So yeah: in the example image I used a Math/Add effect set to 1. |
![]() Chooses the lighter of the previous color and the new color. |
![]() Chooses the darker of the previous color and the new color. |
![]() Overlays two normal maps together, then normalizes. Note: In the example image I went ahead and added a Conversion/Height to Normals effect to both layers before blending them - the blend mode won't make them normal maps itself! |
![]() Does a greyscale thing...although technically it multiplies the two layers together, adds the RGB colors together and then sets all the color channels to the result. |
The alpha mode changes how the layer affects the underlying transparency.
![]() Blend simply lays on top, always heading towards full opacity. |
![]() Blend Inside blends within the bounds of the existing transparency. |
![]() Erase...erases. |
![]() Replace completely replaces the transparency channel, setting it to the new layer's transparency. |
Masks are a way to restrict the effects of the layer to a certain area; you can create masks in the Masks section.
