Hi there ,
I faced such a problem that with the transition to the new version of Corona 7 hotfix 1 for 3dsmax , I began to notice that the material Corona VolumeMtl began to work incorrectly, unlike the previous version of Corona 6 hotfix 2.
I don't understand what the problem is, but this material began to work much worse with the same settings in both corona 7 and corona 6, and now it became impossible to make an aerial perspective with god rays.
I know that I have come up with an alternative to the corona sky with a not very correct volume effect, this effect also looks very cool, but I still use HDRI maps to illuminate the scene and the effect of corona volumeMtl in corona 6 is much better and more realistic.
Below I have attached images with the same value for the corona volume, which I usually insert into the global volume material in settings with the same values for this material
In the first image I am using a volume corona with absorption values (distance 400000) in corona 6, this is the result that is required, I really like
The second image shows the same material settings only in corona 7, as you can see there is no effect.
In the third image, I tried to reduce the absorption (distance 40,000) to corona 7, but the effect is still bad and not what I need.
On the 4th image, the effect of aerial perspective only in the new version of the corona sky
Please tell me, does anyone know what the problem is? and how to return the previous material without resorting to reinstalling the crown to the previous version.
I will be very grateful in advance for advice and help.
