Creating transparent materials

To create a transparent material:

1. Create or select a material and assign it to a node. See Using materials.
2. In the Library > Materials and Textures > Materials select the material and in the Properties set:
   • Blend Mode to one of these values:
     • Alpha: Automatic
       This sets the blend mode to either:
       • Alpha: Premultiplied when the Premultiply Alpha property for the project or an image is enabled. This is the default value.
       • Alpha: Mixed when the Premultiply Alpha property for the project or an image is disabled.
       See Alpha premultiplication.
     • Alpha: Premultiplied
       This is the default and recommended mode for alpha blending.
       The Alpha: Premultiplied mode expects premultiplied alpha RGBA in the source fragment, and blends the source fragment with the destination framebuffer.
     • Alpha: Mixed
       This mode expects non-premultiplied alpha RGBA in the source fragment, and blends the source fragment with the destination framebuffer.
       For example, use the Alpha: Mixed mode when you dynamically load without preprocessing a texture that uses a fragment shader which does not perform alpha-premultiplication of the RGB color.
     • Additive
       This mode adds the source fragment to the destination framebuffer.
       Use the Additive mode for effects where you want a layer to add RGB color, but not reduce the RGB color of the underlying layer.
     See Blend modes in Kanzi.
   • Blend Intensity to the amount of transparency for your material, where 0 is completely transparent and 1 opaque.
