→Adding lights to a model

For the effect of the source on its environment (the lit area), we must have in the 3D model (the .ac file) a volume that includes the effect (Light Volume). It can be a large cone for spotlights or a sphere for point light. It's important that the light volume is closed, convex and it's normals are oriented outward. | For the effect of the source on its environment (the lit area), we must have in the 3D model (the .ac file) a volume that includes the effect (Light Volume).

The light volume must be part of the geometry of the model and be referenced in the animation file. No need to add a color or an effect to this volume. Light calculation is only done on the fragments covered by the light volume, but has no influence on the color or the attenuation of the light. | |||
All available animations are possible on the light volume, except '''material''' and '''texture'''. It is not possible to change color of lights for the moment, except switching to another animation. Axis and position are in object space and are transformed by the subsequent animations. | All available animations are possible on the light volume, except '''material''' and '''texture'''.
