[osg-users] Render to texture and ClearColor

Hi

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->setClearColor(osg::Vec4(0.0f,0.0f,1.0f,0.0f));

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
