FloatImage (Gray Scale)

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).

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.

When selecting an image, you can select from the list of ArchiCAD images, Octane images, or load from disk.

Texture Load Image Dialog

IMPORTANT: Texturemaps connected to “image”, “alphaimage” and “floatimage” nodes must be an actual image file in your file system, not an image in the ArchiCAD library archive (ie. ArchiCAD Library 16.lcf). Some GDL textures may be in the “lcf” archive, so if the plugin cannot file these texture files, extract the archive as follows:

  1. “File”->”Libraries and Objects””Extract a Container”. Select whichever your current library is (which contain the tree texturemap) – most likely “C:\Program Files\GRAPHISOFT\ArchiCAD 16\ArchiCAD Library 16\ArchiCAD Library 16.lcf”. Extract into your My Document\ArchiCAD 16 Library folder (or similar)
  2. “File”->”Libraries and Objects”->”Library Manager”. Click the library you just extracted in 1 and delete it (X button). Then “Add” and select the folder to extracted to above (it should then display “Object Library 16” and “Zones 16” under “Linked Libraries”.
  3. In the plugin, select “Re-convert from ArchiCAD” for any GDL materials which had texturemaps inside the lcf library.

The above is .pln file specific – so you will need to do the above on a blank document and save as a template if you want it always applied by default.
