reflection depth cutoff

V-Ray V-Ray for 3ds Max Issues
1

I’m just rendering an interior scene which has a view that shows a mirror reflecting a mirror.

I’ve rendered the same kind of view in the past and vray seemed to automatically ‘fog’ the reflections so that you didn’t notice the cutoff point. With 1.5final (and max2008 32bit)I’m getting no fogging and a definate ‘hard’ cutoff point (see the black square in the image below).

Have I missed something fundamental here or is anybody else seeing this?

Regards,

Rob.

Never heard of “auto-foggin”
When the trace depth excedes the one you set - the exit color is used as a reflection/refraction. By default it is pure black. Try to increase it to smth like 32. It will still contain black, but I think you wouldn’t notice :smile:

There are no perfectly reflective surfaces in nature; instead of pure white reflection, use some kind of light-grey and then you will get the auto-fogging, as each successive reflection will become weaker.

It’s funny that a mirror could be considered nature in today’s age.

Well, there are some surfaces close to perfect mirrors that occur naturally; but substitute this for “the real world” if you prefer :slight_smile:

Thanks chaps.

I reduced the reflection down from pure white, increased the max depth in the matls editor and very slightly lightened the exit colour - looks great now :slight_smile: thanks for the help!
