We are aware of the "NaN" issue in Corona 11 Hotfix 1. We can currently offer the following options to tackle it:

If possible, downgrade to Corona 10 Hotfix 3 by downloading and installing it from https://corona-renderer.com/download/old and re-render your scene using this version. Unfortunately, this may not be a valid solution depending on what exact features you are using. Corona 11 features will not be rendered in Corona 10.

Install the newest Corona 12 daily build - https://forum.corona-renderer.com/index.php?topic=41598.0 - please make sure you save a backup of your scene before opening it in a daily build as it may be unstable and may even damage scene files! One possible workflow here would be creating your scene with Corona 11 and only rendering the final shots with a Corona 12 daily build.

We are also planning to release Corona 11 Hotfix 2 soon, which will include the NaN fix. Sorry for this inconvenience!

[Max] I need help! / Re: Network problems on Corona scene

« on: 2024-04-04, 14:27:08 »

I can recommend some general troubleshooting steps that might help.

1. Disable any antivirus software you are using on all PCs (including Windows Defender and Firewall) temporarily to check if the issue is related to this software. You can then turn it back on if it doesn't solve the problem.

2. Add custom inbound/outbound rules in Windows Firewall to allow the necessary network traffic for Corona and 3ds Max. Refer to the guide https://support.chaos.com/hc/en-us/articles/4528128298257-Creating-custom-inbound-and-outbound-rules-for-the-DR-Server-application

3. Disable IPv6 on your network adapters. Follow the instructions in the provided link (https://medium.com/@JockDaRock/disabling-ipv6-on-network-adapter-windows-10-5fad010bca75) to disable IPv6 on your Windows 10 machines.

4. Make sure you have network discovery enabled - https://www.isunshare.com/windows-10/turn-on-or-off-network-discovery-in-windows-10.html

5. Check if you are using the latest version of 3ds Max and Corona which is 3ds Max 2024.2 and Corona 11 HF 1 at present.

6. Check the Windows Services list and ensure that "Function Discovery Provider Host" and "Function Discovery Resource Publication" are started and set to automatic start. Steps are as follows:

Press the Windows key + R to open the Run dialog box.
Type "services.msc" and press Enter to open the Services window.
Scroll down and locate the "Function Discovery Provider Host" service.
Double-click on the service to open its properties.
In the "Startup type" dropdown menu, select "Automatic" if it's not already set to that.
If the service is not running, click on the "Start" button to start it.
Click "Apply" and then "OK" to save the changes.
Repeat steps 3-7 for the "Function Discovery Resource Publication" service.


If the issue persists then feel free to start a ticket with us here: https://support.chaos.com/hc/en-us/requests/new

Try this

Code: [Select]

-- Function to create a plane from a bitmap's dimensions
fn createPlaneFromBitmap bitmap_file =
(
    -- Load the bitmap to get its dimensions
    local theBitmap = openBitmap bitmap_file
   
    -- Create a new plane with exact dimensions as the bitmap
    local newPlane = Plane width:theBitmap.width length:theBitmap.height name:(getFilenameFile bitmap_file) position:[0,0,0] isSelected:true
   
    -- Segmentation of the plane - You may comment out or delete these lines if you don't need segments
    newPlane.widthsegs = 1 -- No segmentation based on your requirement
    newPlane.lengthsegs = 1
   
    -- Setup Corona Physical Material with the bitmap as a diffuse map
    local coronaMat = CoronaPhysicalMtl()
    local correBitmap = CoronaBitmap filename:theBitmap.filename realWorldScale:true
    coronaMat.baseTexmap = correBitmap
   
    -- Close the bitmap as we no longer need it open
    close theBitmap
   
    -- Assign material to the plane
    newPlane.material = coronaMat
   
    -- Select only the newly created plane
    select newPlane
   
    -- Zoom Extents Selected in active viewport
    max zoomext sel
   
    newPlane -- return the plane object
)

-- Function to prompt the user to select a bitmap file and create a plane
fn loadBitmapAndCreatePlane =
(
    local bitmapFilePath = getOpenFileName caption:"Load Bitmap File" types:"Image Files|*.bmp;*.jpg;*.jpeg;*.png;*.tif;*.tiff;*.gif|All Files|*.*||"
   
    if bitmapFilePath != undefined do
    (
        createPlaneFromBitmap bitmapFilePath
    )
)

-- Run the function to load bitmap and create plane
loadBitmapAndCreatePlane()

It seems like you are getting a NAN issue. Do you get a NAN warning in the Corona log?

« on: 2024-04-04, 12:42:44 »

Hi,

The minidump tells us what has crashed but we don't know what exactly triggered the crash. So, we would need the scene file with the repro steps so we can check if only Corona is crashing, or all render engines are crashing.

You can start a ticket and send us the scene file, minidump + repro steps here: https://support.chaos.com/hc/en-us/requests/new

Hi,

I attached a video in which I showed the issue and the solution. See if it helps. In case, you are still getting the same error. It would be best to provide us the scene file by starting a ticket.

Hi, can you try to repro it with other renderers such as Arnold, V-Ray or scanline so we can be sure that it's a Corona specific issue only and not 3ds Max.
