This question is a following of this one
I would like to light the center of a cylindric volume with a gradient light White -> Red -> Blue radially from the center to the border.
I made a test of the lighting one a plane mesh and get this result (after some settings) :
The color gradient is OK
Now I renderer the cylindric volume at the same position than the plane.
And I have this result :
This is nearly what I want.
Nearly, because I had in idea to see a white glow inside the volume and the outter volume seems to hide the center of the object.
I tried to change the density, reflection, and scattering settings of the volume but I didn't succeed to see the white glow.
Is it possible to give transparency to a volume and see the inside lighting with special settings ? Or not ?
