GldiSable (gl_lighting) не имеет значения ⇐ C++

[Anonymous]

У меня есть кубик, вращающийся перед 4 плоскими прямоугольниками, которые меняют цвет. Вызов Gldisable (gl_lighting) не останавливает цвета прямоугольников, влияющих на цвет куба. Как я делаю цвет куба, не затронутым прямоугольными цветами?

Я попробовал GldiSable (gl_lighting), чтобы остановить цвета прямоугольников, влияющих на цвет куба, но он не сработал.>
