Hi All, when usign a Texture2DArray I face a strange issue. Loading images coming from png or jpg file format, everything works fine. When I load the same images from other formats, like dds, tga or tif, I get a GL warning Warning: detected OpenGL error 'set img idx invalid enumerant0' after RenderBin::draw(,)
and no texture shows up.
In particular I'm interested in loading DDS compressed file.
I saw that a patch for loading compressed DDS images to texture array has
been merged already, so I can't understand where the problems lies.
Any setting in the texture/image might help?
Below is the relevant code, and in attachment you find the whole file I used
as an example.
I'm on win, osg 2.8.2
Thank you,
Ricky
osg::ref_ptr<osg::Texture2DArray> pTextureArray = new
osg::Texture2DArray;
pTextureArray->setTextureDepth(imgFileNameVec.size());
// tried both with false and true, same results
pTextureArray->setUseHardwareMipMapGeneration(false);
for (unsigned int i = 0; i < imgFileNameVec.size(); ++i)
{
// NOTE textures in the array must be same size and format.
// apparently there's an issue with images coming from some formats
osg::Image* pImg = osgDB::readImageFile(imgFileNameVec[i]);
if (pImg)
{
pTextureArray->setImage(i, pImg);
std::cout << "added image " << pImg->getFileName() << " to
texArray." << std::endl;
}
else
osg::notify( osg::ALWAYS ) << "Can't open image: " <<
imgFileNameVec[i] << std::endl;
}
// must specify a filter
pTextureArray->setFilter( osg::Texture2DArray::MIN_FILTER,
osg::Texture2DArray::LINEAR);
pTextureArray->setFilter( osg::Texture2DArray::MAG_FILTER,
osg::Texture2DArray::LINEAR);
// set attribute
pSS->setTextureAttribute(0, pTextureArray.get(),
osg::StateAttribute::ON);
