On Open GL : I read here and there that it is a must have for any 3D application. My experience with openGL is not all that great I have it for 2 app : Vue d'Esprit 4 : the open GL makes the program unstable. There is a preview window, but it is tiny and doesn't refresh too often. Cinema 4D : the openGL works all right, but doesn't show as much as Poser does (just untextured preview). I have read that DAZ studio's openGL doesn't show a full textured/transmapped perview yet. So could anyone tell me about an openGL app that shows a preview with textures and transmaps, and doesn't bogs or slows down too much my medium range computer ?
