DDS textures with partial mipmapping do not render #391

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
DDS textures with only some mipmap levels defined do not render (or render as 
black, not sure which). This happens because GL_TEXTURE_MAX_LEVEL is being set 
wrong in LwjglRenderer, it is set to

glTexParameteri(target, GL_TEXTURE_MAX_LEVEL, img.getMipMapSizes().length);

when it should be set to

glTexParameteri(target, GL_TEXTURE_MAX_LEVEL, img.getMipMapSizes().length - 1);

(GL_TEXTURE_MAX_LEVEL should be the index of the maximum level, not the count 
of levels)

Changing this fixed the issue for me anyway. Using latest trunk from svn
