Ogre的透明贴图

Ogre加载模型可以用两种透明贴图，

一种是自带透明信息的PNG格式，material文件里要有sene_blend alpha_blend

material Bill_Texture
{
technique
{
pass
{
ambient 0.588 0.588 0.588 1
diffuse 0.588 0.588 0.588 1
specular 0 0 0 1 10

sene_blend alpha_blend

depth_write off

cull_hardware none // 双面
cull_software none
texture_unit
{
texture checker.png
}
}
}
}

一种是用黑白蒙版（遮罩）贴图的JPG或PNG格式，material文件里要有scene_blend add

material Bill_Texture
{
technique
{
pass
{
ambient 0.588 0.588 0.588 1
diffuse 0.588 0.588 0.588 1
specular 0 0 0 1 10

sene_blend add

depth_write off

cull_hardware none // 双面
cull_software none
texture_unit
{
texture checker.png
}
}
}
}
