Texture Nodes

Float, Gaussian, and RGB Spectrum Texture Nodes

RGBspectrum: The texture is based on the RGB colour that is selected.
GaussianSpectrum: The texture is based on a Gaussian distribution spectrum. The wavelength is used to set the center of the spectrum and the width is used to set how wide the curve is. The narrower the width, the more pure and saturated the colour.

Texture Image Node

In order to properly utilize Image TexturesTextures are used to add details to a surface. Textures can be procedural or imported raster files., the mesh must be UV mapped prior to export from the Modeling software. User can also use the UVMAP node to add basic cubic mapping to the objects without UV maps, or the new projection nodes to support the native Octane mapping functions.

FloatImage: The image is interpreted as gray scale even if it is a full colour image, thus saving GPUThe GPU is responsible for displaying graphical elements on a computer display. The GPU plays a key role in the Octane rendering process as the CUDA cores are utilized during the rendering process. RAM. The Invert checkbox can be used to invert the image (useful for bump and opacity maps.)
Image: An image texture is used for the parameter (mesh must be UV mapped prior to export to properly use the Image type). The image is interpreted as being full colour even if it is a grey scale image, and therefore taking up more GPU memory.
AlphaImage: An alpha image utilizes the images native Alpha ChannelA greyscale image used to determine which areas of a texture map are opaque and which areas are transparent. to provide transparency. This type will only accept PNG and TIF image types.

You can select the image from the Lightwave images list, or enter a image file name. In the node you can adjust the texture power and the texture gamma correction. There is also a switch to invert the texture.

Border mode control sets the repeat texture behavior out of the 0..1 UV range. It is also possible adjust the input UV map with the translation, rotation and scale settings.

In Octane each object can have now up to 3 UV sets. You have the UV Set option in the Texture Image node to select the UV map that will be used by this texture. Currently the LightWave UV map names are not available for this node, so you only can see 1, 2 or 3 as map names.
