If you open a scene with a number of cameras exceeding the value in the settings, the new maximum value will be set automatically (3DS Max will need to be restarted)
Go to the 3DS Max Start-up block
Tick the checkbox if you want the Camera Switcher panel to automatically open and snap to the left edge of the screen when you launch 3DS Max (recommended)

EPC Camera Switcher

Colored labels to the left of the camera buttons make it much easier to navigate the Camera Switcher if your scene has a lot of rooms and cameras
One color is automatically assigned to one group of cameras with similar names
We strongly do not recommend using standard automatic camera names such as CoronaCamera001, CoronaCamera002 – it is better to name the cameras Kitchen_001, Kitchen_002 and Living room_001, Living room_002, etc. This will allow you to visually separate groups of cameras by color, as well as send only cameras of the same color to Batch Render in 1 click (see Batch Render section in this guide below)

How to use colored labels

Hold Ctrl on your keyboard and click on the button with the name of the desired camera
Enter a new name for the camera and click Rename

EPC Converter

Open the EPC Converter panel
Carefully review the conversion process displayed in the EPC Converter panel.
Check the "I've understood" checkbox if you understand how EPC Converter works (EPC Converter's results cannot be undone).
Click Convert.
After EPC Converter completes, all EPC settings will be converted to Scene States and Render Presets. The Batch Render queue will be automatically populated from all cameras (with the Scene States and Render Presets stored in it). The EPC plugin will be removed from all cameras. A window will open for saving the converted scene under a new name.
After saving the converted scene, you can send it along with the EPC_Render_Presets folder (located in the project folder) to another PC via DR, or to a render farm or to colleagues, even if they don't have EPC installed.
Attention! If rendering via DR is required, enable and properly configure DR in the Corona Render settings before launching EPC Converter.
Caution! To use Render Presets files, the recipient's 3DS Max and Corona Render versions must match your 3DS Max and Corona Render versions.
Caution! The converted scene is created exclusively for rendering on a PC without EPC using the standard 3DS Max Batch Render (even when rendering a single angle) and is not designed for making changes or edits.
If you've read this far, tell your colleagues that it's time to stop wasting their time on unnecessary manual switching of Scene States and Render Presets for each camera. Thanks to you, they can get their EPC version for the same price as you (regardless of whether they're a student at any school or have a promo code).

How to prepare a scene for a render-farm or transfer to colleagues in 1 click

After starting Batch Render, the status of the position in the queue becomes «Failed» and the render stops

This problem may appear due to the way 3DS Max works with cyrillic paths names for files and render elements
Clear all file paths for each render element in the render settings
Disable the «Save File» checkbox in the render settings
Do not use cyrillic naming when choosing a folder to save Batch Render files and when creating names for cameras
Remember that the letters «С» and «C» (as well as many other letters) look the same in both Russian and English
Set new folder names for saving Batch Render files and names for cameras exclusively in the English
Set new names for LightMix channels exclusively in English

How to fix 3DS Max interface and menu slowdown

Uncheck "Improve Quality Progressively" in the viewport settings. Periodically monitor this checkbox (it should always be unchecked), especially when working with projects created before installing EPC.
Remove all other scripts and plugins that control cameras and their settings.
Disable all antivirus services in 3DS Max that are constantly running in real time (see the Prune Scene and 3DS Max Scene Security Tools settings in the settings).
Always run 3DS Max as Administrator (enable this checkbox in the 3DS Max desktop shortcut settings).
Reduce the maximum number of cameras in the EPC settings if you don't use that many cameras in your projects.

HDRI and Corona Sky Map do not change when switching cameras

This situation occurs if you manually duplicated the camera in the scene or because of an incorrect Pivot position of the camera
The first step of the solution is not to allow 2 cameras to have the same coordinates (camera and target) – or create new angles only using the EPC Camera Switcher (hold Shift on the keyboard and press the button of the desired camera)
The second step of the solution is to click the camera button in the EPC Camera Switcher and click Center Camera Pivot in the Camera Align block of each camera. Then align the camera orientation using the axis alignment buttons if necessary

How to ensure flawless EPC performance

Set the system screen scale to 100% to avoid possible distortions in the EPC interface (right-click on the desktop ► Display Options ► Scale and Layout).
Always run 3DS Max as Administrator to ensure full EPC functionality (enable this option in the 3DS Max desktop shortcut settings).
Always uncheck "Improve Quality Progressively" in the viewport settings, as it slows down the 3DS Max interface and the Material Editor window. Periodically check this option (it should always be unchecked), especially when working with projects created before installing EPC.
Only start working with EPC in a new scene, and in the latest version of 3DS Max and Corona Render, as it can affect the performance of the EPC. Old scenes created in previous versions of 3DS Max and Corona Render may not support all new EPC features.
Remove all other scripts and plugins that control cameras and their settings.
Disable all antivirus services in 3DS Max that are constantly running in real time (see the Prune Scene and 3DS Max Scene Security Tools settings in the preferences).
Periodic checks for the maximum number of cameras to avoid wasting system resources.
Do not use Cyrillic characters when creating camera names and selecting the path (and destination folder) for saving Batch Render files.
