The max hardware accelerated lights that OpenGL can supports is 8 (GL_LIGHT0-7).

But, I would strongly suggest researching lightmapping and radiosity. Its a much faster alternative, and allows for as many lights as you want! http://www.opengl.org/discussion_boards/ubb/smile.gif

It has to support AT LEAST 8 lights, not MAX 8 lights. Any implementation can choose to support as many light as it feels like, as ling as it supports at least 8 lights.

For implementations that suports more than 8 lights, lights are identified with GL_LIGHT0+n, where n is the light number.

And the specs doesn't say anything about whether the light must be HW or SW, as long as they are supported, everything is fine.

To get the number of supported lights, use glGetIntegerv along with GL_MAX_LIGHTS.
