+    - `RESOLVE_SCRIPT_LIB`
+
+    It adds $RESOLVE_SCRIPT_API/Modules to PYTHONPATH.
+
+    Additionally it sets up the Python home for Python 3 based on the
+    RESOLVE_PYTHON3_HOME in the environment (usually defined in OpenPype's
+    Application environment for Resolve by the admin). For this it sets
+    PYTHONHOME and PATH variables.
+
+    It also defines:
+    - `RESOLVE_UTILITY_SCRIPTS_DIR`: Destination directory for OpenPype
+        Fusion scripts to be copied to for Resolve to pick them up.
+    - `OPENPYPE_LOG_NO_COLORS` to True to ensure OP doesn't try to
+	use logging with terminal colors as it fails in Resolve.
