我估计DC只是硬件上支持，但是并没有实际使用环境凹凸贴图的游戏，因为本身PC上的兵人就是数量很少的支持游 ...

都23多年前的主机了，DC真有凹凸贴图游戏早就被人贴出来了，世嘉的主机游戏只要比别家强上哪怕那么一丁点，世嘉粉丝们就能吹上天，如果真的有凹凸贴图的游戏还不集体高朝，怎么23年来就没看见有人提过。

刚刚又去google了下国外玩家的讨论，结论也是DC硬件上支持凹凸贴图，世嘉官方也给出了DEMO和SDK，但是大家都没有找到有实际发售的商业游戏使用这个技术，附件是世嘉给的DEMO

是的世嘉死忠总给人很牛逼高人一等的感觉

看兵人的2个版本对比差距还是很大的，如果DC上有这样的效果肯定早就被挖出来了

不错!总算有点真正的干货了，DEMO有下载 或 视频吗？
