From fc1f5bded46afbb9b16fffe9e4c7f7c212566255 Mon Sep 17 00:00:00 2001 From: Alexander Gavrilov Date: Sun, 19 Jan 2020 12:44:34 +0300 Subject: Depsgraph: fix false positive time dependencies for simple drivers. The dependency graph has to know whether a driver must be re-evaluated every frame due to a dependency on the current frame number. For python drivers it was using a heuristic based on searching for certain sub- strings in the expression, notably including '('. When the expression is actually evaluated using Python, this can't be easily improved; however if the Simple Expression evaluator is used, this check can be done precisely by accessing the parsed data.
