By planning to use Panda3D for the use of developing a game for commercial purposes it’s a necessity to check all licenses associated with it. I’ve read that Panda3D uses FMOD. By checking their site http://www.fmod.org/ifmodlicense.html. I noticed that you cannot use FMOD for commercial purposes unless you pay them essentially. Now for Panda3D in general it is OK as Panda3D is free, however, any application that is built for sale that uses Panda3D should be in violation of FMOD’s license correct? If this is true what other APIs could be used to handle sound and at the same time be compatible with Panda3D.
