[Solved]Ogre stencil doesn't work on Nexus5

[fallout1018]

Hi, All
I just wrote an Ogre3D demo, in witch I create a RenderQueueListener to implement the stencil effect(the main code is below). I found the codes works well on Sumsung glaxy 4(I9500),but it cannot work on Nexus 5.
Any suggestion or would u please tell me why did this happen .

Code: Select all

      
                Ogre::RenderSystem * rendersys = Ogre::Root::getSingleton().getRenderSystem();
                if (queueGroupId == DRAW_STENCIL_SHAPE)
	        {
			maskMaterial->getTechnique(0)->getPass(0)->setColourWriteEnabled(false);
			rendersys->clearFrameBuffer(Ogre::FBT_STENCIL);
			rendersys->setStencilCheckEnabled(true);
			rendersys->setStencilBufferParams(Ogre::CMPF_ALWAYS_PASS,1, 0xFFFFFFFF, 0xFFFFFFFF,Ogre::SOP_KEEP,Ogre::SOP_KEEP,Ogre::SOP_REPLACE,false);
		}


		if (queueGroupId == USE_STENCIL_SHAPE)
		{
			rendersys->setStencilCheckEnabled(true);
			rendersys->setStencilBufferParams(Ogre::CMPF_NOT_EQUAL,1, 0xFFFFFFFF, 0xFFFFFFFF,Ogre::SOP_KEEP,Ogre::SOP_KEEP,Ogre::SOP_KEEP,false);
		}

Hi All,
I had solved the problem. The reason is, on Nexus5, Ogre3D use the "minAttribs" witch does not config the EGL_STENCIL_SIZE for the glcontext. Thanks for your attetion .
