# Cannot increase Samples past 1

In my quest to improve rendering times with Cycles I managed to break my file (I think). Now, when I enter (or slide the cursor) an e.g. 12 value in the Samples box, I get the following message: bpy.context.scene.cycles.samples = 1 Can't edit driven number value, see graph editor for the driver setup.

Choosing a preset from Sampling Presets doesn't reset the sample value.

I've even tried to open the Python console and set it from there, but it still doesn't change the UI, nor the actual render. Consequently nothing (visible) renders with a sample of 1.

Any pointers on how to revert my rendering samples much appreciated.

• This is such a fundamental feature the issue is likely quite deep, I'd recommend deleting the file(s) and re-downloading the .zip and running it. – VRM Jan 3 '16 at 18:51
• Is it perhaps the input field filled with a different colour than the others? – Carlo Jan 3 '16 at 18:58
• Whether the Samples slider is pink? Seems that you added driver to the samples amount. Hover mouse over that samples value and press Alt+D (delete driver).This can be done also from Graph Editor (like proposed by Blender) but it's a little bit more complex. – Mr Zak Jan 3 '16 at 19:00

You may have somehow added a driver to that value (e.g typing #frame in the field).
