Thank you guys :)
Both techniques works. actrask's method seems to be more easy & handy to me for now.

[Max] I need help! / How can I see Corona light material texture on 3ds max viewport?

« on: 2019-05-12, 00:56:16 »

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?

[Max] General Discussion / Falloff works great on Zoomed renders but not when looking from distance...

Thank you Sprayer. Yes, this is what I want on atmosphere edge. But there's a problem.
On zoomed renders your falloff method works great, I copied your falloff map to mine, both looks well in zoomed but both looks fake on zoomed out renders, specially mine :)
in fact adding falloff affects atmosphere's realistic look.

Thanks juancarlosgzrz for your reply but actually I couldn't reach to my wanted result.
I used radial_gradient.osl too but I may missing something, and I can't get them to work as realistic fade on edge of atmosphere.
Actually I can reach my wanted effects in simple Corona MTL like assigning a FallOff map or GradientRamp to Opacity slot and making edges go fade but when using CoronaVolumeMaterial, it behaves as sharp edge shrink instead of fade.
I uploaded 3DsMax scene file with materials I used on slate material editor. I hope someone can help me.
Thanks.

Here is the link to "HOW TO CREATE PLANETARY ATMOSPHERE WITH CORONA C4D" by Shawn Astrom.
https://lesterbanks.com/2018/11/planetary-atmosphere-corona-c4d/

I tried to go step by step by his guides, not in C4D but inside 3DS Max and corona.
I noticed that max version of corona, lacks the "Mix Mode" option for texture in Corona Volume Material in Absorption & Scattering section.
He uses Fresnel map in both Absorption & Scattering texture with Mix Mode set to Multiply to fade edges of atmosphere.
Anyone know how to do same or something similar to reach that fade effect on edges of Atmosphere?
I tried to reach that with Corona Distance & Fall off map but with no success.
Here's my render

[Max] Resolved Feature Requests / Re: Animated render region

« on: 2017-11-30, 19:02:05 »

I think I find the solution :)

Create a simple 1x1 seg. plane and convert it to editable poly.
Animate its position or vertices based on your needs (it will be your animated render region)
Now just assign a CoronaMTL with refraction set to 1 and IOR set to 1 too. (leave the rest of settings as default)
Finally set Corona setting to render selected (from include/exclude list)

And you're Done (^_^)
____________________________________________
for better result :

After creating and animating  the plane as your Animated Render Region
-Uncheck followings in the Object Properties :
             "Cast Shadows" & "Receive Shadows" & "Visible to Reflection\Refraction"
-For material do:
             CoronaMtl
                 Diffuse = 0
                 Refraction = 0.01
                 IOR = 1
                 Opacity = 0
-in Render Setup > Scene tab > Render Selected Mode = "Include/Exclude list" and select plane after clicking on "+"
