When rendering on multiple computers over a network, the  calculation tasks are split and repatriated by the Render Manager to the Clients.


- A physical network is requested, wireless networks may slow down very much the process 

- There is no limitation of the number of Clients you can connect to the same  Render  Manager 

- The network can be composed of both, Mac and Windows 

- Client computers should have similar configuration to that running Artlantis, with special regard to the number and power of the processors, as well embedded RAM. (The graphic card is not relevant , since it does not participate to the process.) If there are big differences between the computers, the weakest will take over the lead, and may produce crashes.

- It is imperative to run the very same and latest version/subversion of Artlantis for the Clients too. If you updated Artlantis, you have to download the same updated Client app from the Artlantis website and install it. ( uninstall the existing Client first).

- Exclude Artlantis and all the related apps (Render Manager, Client...) of the antivirus/firewall of each computer


Allow Artlantis in your firewall or proxy and exclude the following path from your antivirus :
  • C:\Program Files\Artlantis Studio x   
  • C:\Users\<user>\AppData\Roaming\Abvent_Artlantisx   
  • C:\Users\<user>\AppData\Local\Temp\Abvent   
  • C:\Users\Public\Documents\Abvent\Artlantis
  • In the System Preferences, Security and Privacy tab, check if the FileVault and Firewall are on. If they are, exclude Artlantis and its components from them (Batch Render, License Manager...)
  • OSX 10.14 and higher: Allow Artlantis and its components in the System Preferences > Security & Privacy > Privacy > Accessibility

- Run the Render Manager and the Client apps on an admin session

  On MAC:  

Add administrator rights manually to Artlantis as it is described below:
Add administrator privileges access to Artlantis on Mac


- Only one Render Manager at a time can be run on the same network

- Make sure the names of the rendered images, or folders and paths don't contain specific characters (ü, ?, &, +, %, (, ), …)

- Send your renderings to a local folder, not to a synchronized folder like Dropbox or a server


- When  the calculation starts, one of the clients calculates the irradience cash and distributes the tasks to the rest of the Clients. This is an automatic process , you cannot control it.

- If a client becomes seamlessly disconnected, i.e. the dot changes to read, the calculation task is automatically reassigned to another computer. 

- If you meet crashes, you may try to run only one of the Clients and check what happens. 

- you may do the following test (to exclude the probability of a faulty object, geometry which may cause a crash):

- Open the demo scene file you can find here: 

on PC: /Users/ Public/Public Documents/Abvent/Artlantis/ Scenes

on Mac: Macintosh HD/Users/Shared/Abvent/Artlantis/Scenes

- Choose one of the views to be rendered later.

- Without changing anything, save it as an archive file on your desktop.

- Close Artlantis, open the Render Manger with the Clients and start the calculation.
