New Dependency Graph - "frame" python driver expression not working
Closed, ResolvedPublic


Windows 64bit 2.78a

When "frame" is used as expression to drive a value (whether node value, mesh value, or custom property) it does not update upon frame change. User can also manually change the value despite the driver being enabled.

"frame" driver works fine with identical versions with old depsgraph enabled.

I remember fixing related issue. Since there are multiple ways such a driver is created please attach simple .blend file with your particular driver which fails.
