Octane Texture Image

Texture Image Node

In Octane Render each object can have up to three (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 These correspond to the first three (3) VMAPs in the LW Modeler VMAP panel}.

Texture Image Node Inputs/Outputs

The Texture Image Node has a number of inputs:

• Power: Controls the image brightness. Lower values cause the image to appear darker on the surface.

• Gamma: Controls the input image's luminance, and it can tune the image or color-correct the image.

• UV Set: Dropdown to choose the UVMap to use (the first three VMAPS are available)

• Translate U: Move the UV Map in U coordinate space

• Translate V: Move the UV Map in V coordinate space

• Rotate UV: Rotate the selected UVMap

• Scale U: Scale the texture along the U axis of the UV Map

• Scale V: Scale the texture along the V axis of the UV Map

• Projection: Accepts a Projection node. If nothing is connected to this input, the Image texture uses the surface's UV texture coordinates by default. For more information, see the Projections section in this manual.

• Procedural: Allows you to use a LW Procedural as an Input to the Texture Image node

• Baking Texture: Allows you to use an Octane Procedural texture as an input to the Image Node (for Baking)

Texture Image Node Attributes

Node Type

There are four (4) options in the dropdown in the Octane Texture Image node.

• Color 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 color even if it is a gray scale image, and therefore taking up more GPU memory.

• Float Image: The image is interpreted as a gray scale image even if it is a full color image, thus saving GPU RAM. The Invert checkbox can be used to invert the image (useful for bump and opacity maps.)

• Alpha Image: An alpha image uses the images native Alpha Channel to provide transparency. This type will only accept PNG and TIF image types.

• Tiled Image: The Tiled Image Node Type is used to support the use of UDIMs with Octane Renderer for LW. The number of UDIM tiles MUST be set manually using the 'U Max Tiles' and 'V Max Tiles' attributes within the Texture Image Attributes panel.

• LW Image: Pick the image to be used as a texture from the dropdown of loaded images.

• Load Image: Load the image selected to be used as a texture

• Texture From File: Select a Texture from disk.

• Power: Controls the image brightness. Lower values cause the image to appear darker on the surface.

• Gamma: Controls the input image's luminance, and it can tune the image or color-correct the image.

• Invert: Inverts the image, which is useful for Bump and Opacity maps.

• Linear Space Invert: Inverts the image after conversion to linear color space.

• Border Mode: Sets the behavior of the space around the image if it doesn't cover the entire geometry. Wrap Around is the default behavior, which repeats the image in the areas outside the image's coverage. If you set this parameter to White Color or Black Color, the area outside the image turns to white or black, respectively.

• UV Set: Dropdown to choose the UVMap to use (the first three VMAPS are available)

• U Translate: Move the UV Map in U coordinate space

• V Translate: Move the UV Map in V coordinate space

• UV Rotation: Rotate the selected UVMap

• U Scale: Scale the texture along the U axis of the UV Map

• V Scale: Scale the texture along the V axis of the UV Map

When a LightWave Procedural textural is plugged into the Procedural node input then the following attributes are available:

• Procedural Raster Size: Sets the size of the Procedural Map to be baked (from 256 x 256 to 32K x 32K)

• Mirror Tile:

• HDR Raster:

When a Octane Render Procedural is plugged intro the Baking Texture node input, the following Attributes are available.

• Baking Resolution: Set the baking resolution.

• Baking Samples / Pixel:

• Baking as HDR Linear: Bake the image to high dynamic range.

• Baking as RGB: Bake the image to RGB

When the Image Type is set to 'Tiled Image' the following attributes are available:

• U Max Tiles: Sets the number of U Tiles for a Tiled Image (UDIM) textures

• V Max Tiles: Sets the number of V Tiles for a Tiled Image (UDIM) textures
