At the moment the Merge function in CIE is there for merging multiple images from a distributed Rendering nodes. Therefore it uses an "ADD-function". If I am not mistaken.

It would be great if we can have an optional "MIX-function" for merging multiple images.
In this way it will be possible merging an image with a "region render" image or "render selected" image. And even get merged render elements.

Hi there,

for an upcoming project we will have to camera match drone footage (stills). The drone camera will be a Sony A6500 with a Zeis 16-35 mm F4 lens
We are investigating from which positions we need stills and shots.
So we are adapting the render output size and the Corona Camera settings (3DS Max) to mimic the Sony camera and lens.
- If I am not mistaken the Film width (mm) parameter in Corona Camera should be the value off the sensor size of the camera. For the Sony A6500 this should be 23.5 mm (sensor size = 23.5 mm x 15.6 mm) source: .
But the tooltip mentions a value of 25.1mm for ASP-C digital SLR's. Which refers to the Classic film negative format

- Considering the focal length of the lens AFAIK when setting the film width for an APS-C camera we do not have to take the crop factor (1.53 for the A6500) into account. So 16mm stays 16 mm.

So, should we use the 23.5 mm or 25.1 mm for the Film Width and may we ignore the crop factor to get approx the correct results?

We were under assumption that in Corona 4 Lightmix recognizes Corona lights in Xrefs and created the proper Lightmix layers according to the choices we made (instances,  etc .....)
In corona 5, lightmix does not recognize Corona lights in Xrefs. I have looked on the forum and helpdesk but could not find any related posts.
So, or we are wrong, or this is a bug?

We loved to work on this project.
Took a while to finish and render, but Corona did the job as expected!

 we are planning to make use of Deadline instead of Backburner. I know how to install Deadline on clients.
I would like to install the Repository and the MongoDB database on my Qnap Nas (yes fast enough and 10GB network).
Is there anyone out there who did this already? And If so, how?
Or is it better to install the repository on a windows PC and have s storage folder on the Nas?

Looking forward to your advice

Hardware / Workstation: Intel Skylake-X or AMD Threadripper
« on: 2018-02-19, 18:00:53 »

I am planning to buy a new workstation and wondering If I would go for Intel Skylake-X or AMD Threadripper.
AFAIK MAX is multi-threaded for rendering but all other tasks are single threaded.
Does anyone know if Interactive Rendering is multi or single-threaded?
If the latter I am planning to go for Intel Skylake due to better single threaded performance.
Or will this not be noticeable?


All our files are stored on a NAS.
In the Corona Image Editor (CIE) we save a config file of the tone mapping settings for each render we process. LUT's are stored on the NAS as well.
Every workstation (WIN10 Pro) has the same mapped network drives to different folders on the NAS.
For some reason and from time to time windows does not automatically connects to the mapped networks drives.
If this is the case you can open a render in CIE and load the conf file. It will load all settings except the LUT, because it refers to the C drive instead of the mapped network drive.
So an error message will be welcome.

Hi there,

for converting Vray models towards Corona it is necessary to install a Vray trail license. In the past we did not have any issues.
After installing Max 2018 + the latest Vray trial license and from the moment the trail license has expired, each time we save a file which still have some Vray materials, Max is crashing.

When the announcement of the marriage between Corona and Vray was made, the Devs stated that in the future it should be possible to render Vray materials in Corona and the other way around. So in the meanwhile, could there be a solution for the problem I described?

I should have post this on the Vray forum, I registered but could not make a post.

Or is this an Autodesk issue?



CGI Fridays take the place of our MUG / 3D Meetup for people in the creative industry. Everyone doing anything 3D, VFX and Motion Design is invited to join us. We’ll be meeting in a pub in Antwerp, Belgium where they serve some excellent Belgian beers to get the ball rolling.
It serves to be an informal event where we can all get together, chat about what we’re doing and hang out with like minded people.
Everyone is welcome on the 13th of October starting from 20:00 on the first floor of the Via Via bar. (Wolstraat 43, 2000 Antwerp)
We do ask that you register for free on our Eventbrite page, that way we can anticipate the number of people a little better.

Thanks & see you there
Midge & Johan


Hi there,

At the moment our renderfarm consists out of Intel Xeon machines, we are planning to buy some AMD Threadripper machines to enlarge our farm.
I was told that the Threadripper is handling floating points in a different way then Intel which could result in different noise level outputs for the same render.
Has anyone experienced this? Or other issues? Or no issues?

anyone knows a good source for highres Plywood textures.
I need them for kitchen doors/panels, ....

[Max] Resolved Feature Requests / Integration of Cryptomatte

Hi Devs

I stumbled upon the following article
It would be awesome if you could integrate this software or develop something like this in Corona.
