I sometimes get questions about Octane lighting or lighting in general. I thought I'd make a journal in case it can be of help for people trying Octane.Well, the basic ways of lighting I use are:- a HDRI image (texture environment)- the daylight light (daylight environment)- a geometric shape turned into a light emitter- reflective surfaces... or you can even light a scene with a combination of all of them. Settings in the "Imager" section have a huge impact on end result, especially the film response chosen. Bloom and glare in the "Post processing" are great too.Use Path tracing or PMC Kernel for nicer results, Direct Lighting is fast but tends to look ugly when rendering people.There are basic geometric shapes in Poser's Props/Primitives folder that can be used as lights in Octane. Go to the folder and add for example the "one sided" square.
In Octanes Materials tab you'll see an item called "square_1". Open it and you'll see a node called "Preview". Change node type from Glossy to Diffuse. You'll then see a node called "Emission". Change it from "Not Connected" to "Black Body or "Texture Emission". "Black body" lets you set the light temperature in Kelvins, "Texture emission" lets you pick a color. Now you have a light you can scale and move around in your scene.
If you have Poser lights in your scene when loading Octane plug-in, you'll notice it renames a light to "Daylight". When you choose "Daylight" as "Environment" use that light to move the Sun into the position you want. If you want to use a texture as a background open the "Sky texture" node and choose "RGB image" and locate the appropriate image on your hard drive. Remember to change the "Projection" node to spherical. You can then rotate the image to your liking in the "Sphere transformation" node.
If you use "Texture environment" you add an image in the same way but you use the "Texture" node.
If you have a scene consisting of a lot of props, or even an interior scene, where you can't see the environment image, you can still use an environment image for lighting purposes.
Well, these are some basic tips. If you find this interesting or need help with something, feel free to comment or ask questions
