Blender 2.8 volume shader problem


Trying to get a smoke effect with a volume shader and am following a yt tutorial. Here is a preview of the tute shader:

and what I have in my viewport:

The tutorial is using 2.8 and I’m on 2.82a. My shader looks horribly low rez and I have been searching for a while but cant find a way to increase it. Also the color pin is missing from the musgrave texture node. Any words of wisdom gratefully accepted.

Change the tile size 16px to 2px or 4px.

Thought I had tried that. Changing to 2 px fix it. Thanks a million DERBENDER!

Your map range node isn’t connected to anything either - is that intentional?
