Hello everyone, I am new to Modelling for Arma 3. I have build a house before. I knew how to import the p3d in the Object Builder from Blender etc. But now I want to build a small lamp. I get the Model of the lamp into the Object Builder and its visible in the eden editor and in the game. But I still don't know how to create a lightsource inside my object, so that the lamp actually emitts light and its visible ingame. Thanks for your help
