Hi try to attach depth buffer pCamera->attach(osg::Camera::DEPTH_BUFFER, GL_DEPTH_COMPONENT32) or set pCamera->setImplicitBufferAttachmentMask(osg::Camera::IMPLICIT_DEPTH_BUFFER_ATTACHMENT)
if you use stencil, you need to attach packed depth stencil buffer instead. If you dont need depth buffer on this camera you should disable depth test and set clear mask to color only, then it wont complain about missing attachment.
