Environment variables
=====================
smartRender can be driven with environment variables which are
described in the following. Note that all environment variable values are
strings, even when using booleans like ``True`` or ``False``.

CRAGL_NO_WEB
------------
If your machine is not connected to the web we recommend to set the environment
variable ``CRAGL_NO_WEB`` to ``'True'``. This will speed up launching
smartElements.

CRAGL_SMARTRENDER_ADDITIONAL_TRANSCODING_ROOTS
----------------------------------------------
Transcode templates let you perform automatic transcoding jobs after a render
has finished. All transcoding templates live in
``smartRender/custom/transcode_templates`` in your smartRender installation
folder. You can however also point smartRender to additional folders to look
up for transcoding templates by adding one or multiple paths to the environment
variable ``CRAGL_SMARTRENDER_ADDITIONAL_TRANSCODING_ROOTS``.

Similar to adding paths to the ``PATH`` and ``PYTHONPATH`` environment
variable, you can specify multiple paths by concatenating them using the
operating system path separator. Under Linux and MacOS this is a **colon**.
Under Windows this is a **semicolon**.
