CoronaMix doesn't show correctly in viewport

Corona Corona for 3ds Max Issues

Hi =)
as in the title, CoronaMix doesn’t show correctly in viewport.
The same map, created with Composite, is perfect.
The map is created by using three different UVW modifiers, with 3 different Mapping channels.

And, is it normal this huge difference in rendering time between the different blending modes?

I think the rendering time difference could be related to the out of range albedo.
