+# Autodesk 3ds Max 2025 conda build recipe
+
+> **Autodesk Cloud Rights:** Autodesk 3ds Max has its own licensing requirements separate from AWS.
+> Confirm you have the appropriate licenses before proceeding. See additional details on
+> [Autodesk Cloud Rights for 3ds Max](https://www.autodesk.com/support/technical/article/caas/sfdcarticles/sfdcarticles/Subscription-Benefits-FAQ-Cloud-Rights.html).
+
+## Creating an archive file for Windows
+
+The Windows installer requires Administrator permissions that are not available in most conda package
+build environments, such as on Deadline Cloud service-managed fleets. Follow these instructions to
+install 3ds Max 2025 on a freshly created EC2 instance as Administrator, and create an archive file
+for use by the conda build recipe.
+
+1. Launch a fresh Windows Server 2022 instance (any current Windows Server AMI with enough vCPUs and RAM works).
+   1. From the AWS EC2 management console, select the option to Launch instance.
+   2. Enter instance name "Create Windows 3ds Max archive".
+   3. Select "Microsoft Windows Server 2022 Base" for the AMI.
+   4. Select an instance type with enough vCPUs and RAM, for example c5.4xlarge has 8 vCPUs and 16 GiB RAM.
+   5. Select "Proceed without a key pair" for the "Key pair (login)" option.
+   6. We will use SSM port forwarding to avoid sending RDP protocol traffic directly over the internet.
+      1. Make sure that "Allow RDP traffic" is unchecked.
+      2. Make sure the security group does not allow any inbound traffic.
+      3. Make sure to remove any public IP addresses from the instance.
+   7. Set the storage to at least 64 GiB. Adjust other settings as you like, e.g. if you want an encrypted volume of type gp3.
+   8. Select "Launch instance."
+   9. If it asks, select "Proceed without key pair" and proceed with the launch.
+   10. Once it launched, navigate to the instance detail page. Select "Connect," and with "Session manager" selected, again select "Connect."
+       If it says "SSM Agent is not online," you may have to wait a few minutes for it to initialize.
+   11. Create a secure password for the Administrator account. From the Administrator PowerShell window that session manager,
+       enter the following command with your secure password substituted to change the password.
+       1. `net user Administrator MY_SECURE_PASSWORD`
+2. Connect to the instance with SSM port forwarding and RDP.
+   1. Install or update the AWS CLI v2 from https://docs.aws.amazon.com/cli/latest/userguide/getting-started-install.html.
+   2. Install or update the Session Manager plugin from https://docs.aws.amazon.com/systems-manager/latest/userguide/session-manager-working-with-install-plugin.html.
+   3. Run the following command, using AWS credentials that have suitable permissions, to start the SSM port forwarding. Replace INSTANCE_ID with the one you launched.
+      1. `aws ssm start-session --document-name AWS-StartPortForwardingSession --parameters "localPortNumber=3389,portNumber=3389" --target INSTANCE_ID`
+   4. Open RDP, and enter the following connection details:
+      1. Computer: `localhost:3389`
+      2. User name: `Administrator`
+   5. Enter the password you set for Administrator after you created the instance. You should now have a remote desktop session to your instance.
+3. Install 3ds Max 2025 on the instance.
+   1. Download the 3ds Max 2025 installer for Windows from Autodesk (for example via Autodesk Access).
+   2. Run the installer on the EC2 instance and complete installation using the default settings.
+   3. *(Optional)* Install the `deadline-cloud-for-3ds-max` Python package inside 3ds Max if you want the Deadline Cloud
+      integration baked into the package. Note that doing so pins the adaptor at archive-creation time and skips runtime
+      upgrades that the Deadline Cloud conda channel would otherwise provide; for production fleets, prefer letting the
+      channel deliver the adaptor at job-init time.
+4. From an Administrator PowerShell window, create the archive from the installed files and capture its hash.
+   1. `Compress-Archive -Path 'C:\Program Files\Autodesk\3ds Max 2025' -DestinationPath Autodesk_3dsMax_2025_Windows_installation.zip`
+   2. `(Get-FileHash -Path "Autodesk_3dsMax_2025_Windows_installation.zip" -Algorithm SHA256).Hash.ToLower()`
+5. Upload the zip to your private S3 bucket. You can use a PowerShell command like
+   `Write-S3Object -BucketName MY_BUCKET_NAME -Key Autodesk_3dsMax_2025_Windows_installation.zip -File Autodesk_3dsMax_2025_Windows_installation.zip`.
+6. Terminate the EC2 instance.
+7. Download the zip file to the `conda_recipes/archive_files` directory in your git clone of the
+   [deadline-cloud-samples](https://github.com/aws-deadline/deadline-cloud-samples) repository for
+   submitting package build jobs, and update the Windows source artifact hash in `meta.yaml`.
+
+The build script installs `pywin32` into 3ds Max's embedded Python to enable automation and exports
+environment variables (`ADSK_3DSMAX_*`) so jobs can find both the GUI (`3dsmax.exe`) and batch
+(`3dsmaxbatch.exe`) executables. See the *Notes on environment variables* section below for details.
+
+## Build tool
+
+This recipe uses `conda-build` to stay consistent with the existing 3ds Max test pipeline. Migration to
+[`rattler-build`](https://github.com/prefix-dev/rattler-build) (already adopted by `blender-5.1`,
+`maya-2026`, and others in this repository) is tracked as a follow-up — feel free to open an issue or PR.
+
+## Notes on environment variables
+
+The activation script exports the following variables so jobs and the
+[`deadline-cloud-for-3ds-max`](https://github.com/aws-deadline/deadline-cloud-for-3ds-max) adaptor can
+locate the right executable:
+
+| Variable | Path | When to use |
+| --- | --- | --- |
+| `ADSK_3DSMAX_BATCH_EXE` | `…/3ds Max 2025/3dsmaxbatch.exe` | **Default.** Non-GUI batch render. Compliant with Autodesk Cloud Rights, which allow up to 10 batch render licenses per GUI subscription seat. |
+| `ADSK_3DSMAX_EXECUTABLE` | `…/3ds Max 2025/3dsmax.exe` | GUI executable. Use only if your Autodesk subscription's GUI seats cover the rendering workload. |
+| `3DSMAX_EXECUTABLE` (`.bat` only) | `…/3ds Max 2025/3dsmaxbatch.exe` | Legacy variable consumed by the current adaptor; kept pointing at the batch exe so existing jobs render with the safer default. |
+
+Limitations:
+
+- POSIX shells cannot export variable names that begin with a digit, so `3DSMAX_EXECUTABLE` is set
+  only by the `.bat` activation script. Bash activation relies on the `ADSK_*` variables.
+- The current adaptor reads `3DSMAX_EXECUTABLE` only. Until
+  [deadline-cloud-for-3ds-max#190](https://github.com/aws-deadline/deadline-cloud-for-3ds-max/issues/190)
+  ships, jobs that need to switch between batch and GUI explicitly will require either a small adaptor
+  hot-patch or a fleet-level override of `3DSMAX_EXECUTABLE`. Once that adaptor change lands, the
+  adaptor will read both `ADSK_3DSMAX_BATCH_EXE` and `ADSK_3DSMAX_EXECUTABLE` and pick the right one
+  for the job.
+
+## Renderer plug-ins (e.g., Corona)
+
+If you intend to render with Corona or other third-party renderers, ensure their DLLs are present in the
+3ds Max plug-in search path (e.g., `Autodesk/3ds Max 2025/Plugins`). The main `3dsmax` package does not
+carry Corona binaries; use the `3dsmax-corona` package to place the real Corona DLLs into the
+environment. Without that package (or manually copied DLLs), Max will warn about missing plug-ins and
+the adaptor will fail.

+# 3dsmax-corona conda package
+
+This package repackages the Corona Renderer plug-in for Autodesk 3ds Max into a conda-installable bundle. It should be installed alongside the matching `3dsmax` conda package.
+
+> **Licensing:** Corona Renderer is distributed under the Chaos EULA. You must hold a valid Corona
+> license that covers your rendering workload before deploying this package on a fleet. See the
+> [Chaos website](https://www.chaos.com/corona) for licensing details.
+
+## Contents
+- Corona Renderer payload for 3ds Max (version 13.2) sourced from `archive_files/3dsmax-corona-2025-13-2/win-64`.
+- Windows-only build that copies the plug-in files into the 3ds Max installation inside the conda prefix.
+
+## Usage
+1. Ensure the `3dsmax` conda package for the matching major version is installed.
+2. Install this package via your conda channel (e.g., `conda install 3dsmax-corona-2025`).
+3. Activate the environment; the plug-in will live under the 3ds Max plug-ins directory.
+
+## Building the archive payload
+If you need to refresh the archive payload:
+1. Run the Corona installer `.exe` for 3ds Max on a Windows OS.
+2. After install, copy the Corona files from `C:\Program Files\Chaos\Corona\Corona Renderer for 3ds Max\2025` (or matching year) into `archive_files/3dsmax-corona-2025-13-2/win-64/` in this repo.
+3. Build the conda package (`conda build conda_recipes/3dsmax-corona/recipe`).
+
+## Notes
+- Platform: `win-64` only.
+- License: Chaos EULA (see vendor site).
+- Documentation: https://docs.chaos.com/display/CRMAX
