Vray Next GPU vs Octane Tweet

[Norman_Stansfield]

I own both renderers now. After testing for various features - Octane is much better, and more production-ready. Congratulations, guys! Vray people still believe in CPU, they woke up with GPU but its late. Youre way ahead.
With phoenix fd support in octane and volumetric zdepth passes you win every production challenge with vray gpu (for now). When do you plan direct fume fx support?

One question - where can I change the range of zdepth standard and volumetric? Manipulating zdepth value in Info Pass settings seems to do nothing. Am I missing something?
Second question - how to create a simple fog instead doing it in zdepth postproduction? Enviroment Scattering doesnt seem to work as real fog - it gets dense too early for atmospheric haze.

Best,

Hi Norman_Stansfield,
Next Octane V4 Ai denosiser will denoise volumes and hairs too, this will make Octane render even faster.
An alternative to Environment Medium Radius is to using a fog cube. or use .vdb

By the way, question regarding volumes: does the bug in 3.0 with intersecting volumes was fixed in 4.0?

Less of a 3ds max thing.. but i like the direction otoy is going in re to metal api for mac users.. and playing well with other platforms.. and both cuda and opengl / cl vulkan etc..
Also almost the only company out there posing a development roadmap..!
