i´m currently rendering to a texture using a slave camera
my problem is that i can´t set the clear color to alpha. Each time the slave camera renders a new frame i get a nice blue background instead of the transparent background i´m looking for
i´ve tried with values of 0.0, 0.5 add 1.0 for alpha
camera->setClearMask( GL_DEPTH_BUFFER_BIT | GL_COLOR_BUFFER_BIT);
camera->setColorMask(true, true, true, true);
i´ve created the texture2d attached to the camera from and osg::image with GL_RGBA and GL_UNSIGNED_BYTE formats and also i´ve tried by creating the texture2d with no parameters and setting later the texture->setInternalFormat(GL_RGBA)
any idea of what i´m doing wrong???
thanks in advance
