Materials library

Materials library dialog contains information about Radiance material libraries and their contents. In this dialog user can open, explore and save libraries, and also edit and explore separate materials.

It can be opened from toolbar material_dialog_icon or menu Extensions-> De Luminae-> Global parameters-> Material libraries .

library info

The upper left part of the dialog contains material libraries tree. Tree initially contains only entries for libraries distributed with DL-Light extension, but new user-defined libraries can be added.

Material libraries are text files containing definitions of materials in Radiance format. They are of 3 kinds:

Libraries from the tree can be moved up/down to change their order of appearance. Materials from the tree can be moved (classic Drag-n-Drop) or copied (Drag-nDrop + Ctrl key) to other libraries. Materials from read-only libraries can only be copied to other libraries.

Right part of the dialog contains information about selected entry in the tree. It can be either library or material info.

".cal" calculation files

Some complex materials point to a ".cal" file in their definition, for example BRTDfunc. The input field at the bottom left of the dialog allows to add the path of a folder containing the ".cal" files used. The files located in this folder will be copied to the temporary calculation path.

Only files with the extension ".cal", ".xml" or ".pic" are copied. (This list can be configured in internal preferences.)

Materials info panel

material info

Top part of panel contains material name, library name and image. Material definition follows.

Material definition can be done on two levels: Basic and Advanced.

This version of extension doesn't support complex Radiance materials with patterns and textures.
If material is updated, its image is automatically created and shown few seconds later.
