Edit by Coppelia: make sure to first read this topic about headless mode, this thread is old.

What do you mean with "won't work"?

The log you posted shows Initialization successful which suggests everything should be working fine.

Hello,

those settings are part of a given scene. So edit the scene in the appropriate way (not in headless mode), save it. Then load it in headless mode.

Cheers
