Emission shader low resolution in Eevee I do the following:

I start a new project
I add a new material to the cube
I add emission volume

Then the emission appears with low resolution. If i add the material to a sphere, the emission appears cube-shaped.
How do I get a high resolution or a sphere-shaped emission?
Eeevee only supports box-shaped volumes. To increase the resolution bump up the tile size and samples in rendering/volumetrics.
