This is very useful when new to the NGE, as you can’t plug something in where it can’t be used. Once nodes are placed they can be connected using the colour-coded terminals. Other nodes are available for setting colour, placing images, generating procedurals (like noise), manipulating uv projections, setting displacement, setting emitters and so on. Once you become familiar it is very versatile and can lead to a multitude of new ways for generating materials for example generating a greyscale image using a noise generator, mixing it with a turbulence generator and using the result instead of a bump map for variation on a the skin surface. It may seem a little daunting for anyone unfamiliar with node based systems, but this is by far the easiest way to manipulate materials in Octane (and in my opinion within Daz also). Nodes are available from the pull-out list on the left, can be dragged into the main viewport, and then edited on a node-by-node basis on the right. Mix node – combines two or more of the previous surface nodes.Specular – clear or transparent surface, and.The node-graph of a more complex skin material. Select the node-graph editor (4 in diagram).īelow, I show the nodegraph editor (or NGE) with a simple diffuse material.Adjust settings in the right hand window (3 in diagram). Generate as new light source – will create a new blank diffuse material set up as a simple, textured, or IES profile light emitter.You will normally need to tweak these auto materials, particularly if they are based on iRay shaders in Daz (though this is improving with newer releases). Generate as new material > auto – will take the existing material settings applied within Daz and try to create a suitable material.Generate as new material > blank – will create a new blank diffuse material.Right click a surface window (2 in diagram), and select either:.Materials from the database can be edited/saved as presets once downloaded This material will then be downloaded from the internet and applied. Search the Live Database (not available in demo) – then drag that over to desired surface. This is very useful when setting materials for skin. The new material will be an instance of the original but can be edited.
