Is it just me because I understand these new features.

I recall them being mentioned in the changelog for 4.02.04.00003.. but how they work and where to locate them still eludes me

Can someone please explain

New features:
(*) V-Ray: Initial support for direct rendering of CoronaMtl and most materials from the Corona material library;

Do you need Corona installed for this to work, then again, if you have it installed, why would you be using V-Ray. It is great that there is now initial support for CoronaMtl
and materials from the library, however I imagined loading a Corona scene, would allow me to render the materials, however it just displays errors "Missing rendrer...." etc.
And hitting render, just gives black materials


(*) V-Ray/V-Ray GPU: Add a parameter for additional control of the auto-exposure (camera_autoExposure_compensation);

Where is this located exactly... oh and will there ever be a way to select white / black in the image, so that the auto exposure has something to go by
becasue at the moment, it can vary wildly, from about right to crazy over exposed, al depending on the

Do you need Corona installed for this to work, then again, if you have it installed, why would you be using V-Ray.

Yes, you need to have Corona installed for the moment.

if you have it installed, why would you be using V-Ray

Apparently, it happens If you work mainly with V-Ray, but get a Corona scene or asset from somewhere else and you want to render without touching the original scene setup, this is useful.

It is great that there is now initial support for CoronaMtl and materials from the library, however I imagined loading a Corona scene, would allow me to render the materials, however it just displays errors "Missing rendrer...." etc.

This will be added later on.

V-Ray/V-Ray GPU: Add a parameter for additional control of the auto-exposure (camera_autoExposure_compensation);

It is only controllable from MaxScript (i.e. renderers.current.camera_autoExposure_compensation =0.5). I'm not comfortable exposing this option to the UI just yet, but it is there for those advanced users that might need it.

oh and will there ever be a way to select white / black in the image, so that the auto exposure has something to go by becasue at the moment, it can vary wildly, from about right to crazy over exposed, al depending on the

No, for the moment it is what it is; I don't want to make it more complicated than that with extra settings. The exposure slider in the VFB are always available if you want to do any additional adjustments. In the future, I would like to research some AI-based approach, similar to what is used in many mobile phones nowadays.

Thanks for the detailed explanation Vlado.

So for now at least, we need to have a copy of Corona installed... ok. Of course the ability to render Corona assets without needed Corona to be installed would be. I have never been sent whole scenes, as I am the sole creator on al projects, but I do occasionally come across certain assets, that have been created with Corona, so would be great to be able to just import them into a V-Ray scene and not have to go through the additional steps of manually converting them, for V-Ray.. so I look forward to seeing that ability in the future.

As for the AutoExposure compensation, as I have mentioned before, I really don't use AutoExposure or VFB image correction controls, except for experimentation. Being from a photographic background, I like to have as much control as possible, so prefer to render the scene along with various render elements and do the corrections/adjustments in Photoshop.. but as I've said before, that's how I work, while others like the fact they can make certain adjustments, within the VFB.

What is new with Optix 5.1 AI denoiser is keeping HDR and reducing memory by The SSIM predictor?

[vlado]

The OptiX denoiser works fine with HDR images. However we have not received any updates from NVidia regarding the memory usage. Hopefully they will release an official update soon.

After installing the update of the edu version for 3ds max 2017, 3ds max won't open anymore, it crashes while starting up... :/ What could be the problem and is there a solution ? Thanks !

EDIT: After manually uninstalling the previous version of Vray and installing the latest version, no more problems...

Sadly I still have the square artifact bug witht adaptive domelight in 4.02.05. Please see attached image. I raised contrast and exposure quite a bit, so you can see it better.

Is it still happening with a recent nightly build?

Would love to try, but somehow our nightlies access has expired.
