no way to extract RGBA channels from packed textures
Posted: Thu May 02, 2019 5:55 pm
This is a feature request that is especially valuable to Unity users, but would also benefit all octane users. Please redesign the texture node, or add an additional node that allows for quick isolation of the individual RGBA channels of packed textures. The Unity standard shader, and thus most Unity assets are using packed textures that pack multiple black and white textures into the RGBA channels of a color image. When you go to convert a unity standard shader into an octane shader for more features or control, there is no straightforward way to directly access these channels.
