This pages describes solutions and alternatives to make Substance Painter able to run via Remote Desktop (RDP) on Windows.
By default RDP on Windows runs in an OpenGL context that is non-existent or too low, which makes the application unable to work properly or crash. Substance Painter requires an OpenGL 3.3 context. Below are solutions to mitigate the problem, but there is no garanties they will work as the initial problem is dependent of Windows and some GPU drivers.
Windows Policy Configuration
On Windows 10 it may be necessary to change the Group Policy to allow the GPU to be run while in RDP mode.
To do so:
- Press Win + R to open the execute window
- Type "gpedit.msc" then Enter
- Navigate to Local Computer Policy\Computer Configuration\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Remote Session Environment
- Enable the option Use the hardware default graphics adapter for all Remote Desktop Services sessions.
Windows TSCON command
If the previous Policy change doesn't work, you may try to use the tscon command line. This command disconnect the remote computer and connect a new one to the physical hardware (mouse, keyboard, etc). Then simply running the application and reconnecting remotely should allow to work with the application on the GPU.
- Press the key Windows+R to open the execute window.
- Type cmd and press Enter.
- In the command line type and the following command: tscon 1 /dest:console
- Press Enter
- In the command line type the next command: start "Path/To/Substance/Painter/Folder/Substance Painter.exe" (make sure to change the path to match your computer)
- Press Enter
After these steps, wait a few seconds to let the application startup and then reconnect to your session.
You may have to run the Windows command line in administrator mode in case this procedure doesn't work.
If previous suggestions still don't work we recommend using alternative solutions such as VNC or Teamviewer which support the GPU via remote connections.
