Detailed Description

A shader program builder consists of several different shader graphs used to generate shader code.

A cache of generated shader code is maintained. Generated shaders are by defaults saved in writableLocation ( TempLocation )). This path can be overridden by setting environment variable QT3D_WRITABLE_CACHE_PATH to a valid writable path.

The use of the cache can be disabled by setting environment variable QT3D_DISABLE_SHADER_CACHE.

In most cases, changes made to a graph are detected by Qt 3D and a new cache entry will be generated. One case were this will not happen is when code snippets included by a graphs are changed. To work around that, clearing the cache directory or setting environment variable QT3D_REBUILD_SHADER_CACHE can be used to force shader code to be generated again.
