Re: [osg-users] [osgPlugins] DDS Texture vanish with LINEAR_MIPMAP_LINEAR

Hi, I have a question. Why while reading dds file, to set number of mipmaps it is using function osg::Image::computeNumberOfMipmapLevels( s, t, r ) but not what is written in dds file header ? I think that dds file knows better how many mipmaps it has inside. Thank you! Cheers, Lukasz

Re: [osg-users] [osgPlugins] DDS Texture vanish with LINEAR_MIPMAP_LINEAR

Hi, But for example we have 512x512 dds texture compressed with DXT1 and in header we have 4 mipmaps. In this example is meaningless to compute number of mipmaps, because OpenGL ,with my knowledge, does not generate mipmaps for compressed textures. So setting bigger number of mipmaps is wrong.

Re: [osg-users] [osgPlugins] DDS Texture vanish with LINEAR_MIPMAP_LINEAR

Hi, i probably have solution for this problem, i have found a bug in dds plugin ReaderWriterDDS.cpp Line 633 unsigned numMipmaps = osg::Image::computeNumberOfMipmapLevels( s, t, r ); when compute numMipmaps returns wrong number. this number is less then number of mipmaps in dds file(
