how to merge a multiply layer with a normal layer

To produce a combination of both, the Noise layer's Blend Mode is set to Add, but this produces the clipped values shown in image 3. In the Shader Tree, a Noise layer is added above it the Cellular layer and set as displacement, superseding the lower layer in the tree (image 1). The following example shows how this works.Ī Cellular procedural layer applied as a displacement map. To reduce or eliminate clipping for certain effects that can't be driven higher than 100% (such as Displacement), you may also need to adjust a layer's transparency. Depending on the texture and the blend mode, it may produce values beyond 100%. Add, for instance, takes the values from the two layers and adds them together for the result. The following table show the various Blend Modes, with samples to illustrate the effect.īlend Modes work by calculating the math (as specified) on the individual RGB channels. A layer with a Blend Mode applied only affects other layers below it in the Shader Tree.

For example, a Diffuse Color layer can only use the Multiply mode with another layer specified as Diffuse Color. There must be more than one layer of the same Effect type.Note: Blend Mode results are only visible in the final render or in the Preview viewport.īlend Modes affect the RGB color values (even if you just have black and white specified) and have a couple of rules that need to be adhered to: The mode is specified by left-clicking on the Blend Mode button to open a contextual menu, and then selecting the mode from the available options. Most item layers in the Shader Tree offer a Blend Mode option to combine two or more layers in various ways using mathematical operations. A Blend Mode other than Normal is specified, changing the way the layer interacts with the lower layers.The transparency of the layer is changed to reveal the lower layers.This reveals lower layers outside the masked region. A mask is applied, either as a layer or a surface tag, limiting the effect of the layer exclusively to areas inside the mask.The Shader Tree's layered approach to shading surfaces works in a fashion similar to layers in an image editor such as Photoshop any layer above another obscures the layers below, unless one (or more) of three conditions is true: The key point here is that there must be more than one layer in order for blending to work. The flexibility and power of the Shader Tree is extended with the use of Blend Modes, a means of determining how multiple layers interact with each other.
