Hi.
In VRay & Standard material slots, there are two buttons, "Show Realistic Materials in Viewport" & "Show Shaded Materials in Viewport".
When assigning LightMaterial to an object, it is shown as white by default in 3ds max viewport.
To see the texture assigned for light meterial in VRay & Standard, "Show Realistic Materials in Viewport" button can be used.
But this button disappears when slot is CoronaMtl or CoronaLightMtl.
Is there any way to see it on viewport without rendering?
