From dba9521cf6e2b14a345f7e4a2554e536fb69feff Mon Sep 17 00:00:00 2001 From: Graham Linden Date: Mon, 22 Oct 2018 19:23:10 +0100 Subject: SL-9806 Get dome rendering to not assert the depth test state behind deferred render's back. Make clouds write and test depth to give stars something to depth test against. Add z-bias in star vert shader to force some depth testing of stars against clouds. --- indra/newview/lldrawpoolwlsky.cpp | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'indra/newview/lldrawpoolwlsky.cpp') diff --git a/indra/newview/lldrawpoolwlsky.cpp b/indra/newview/lldrawpoolwlsky.cpp index b9e041a3d5..c4560e89f4 100644 --- a/indra/newview/lldrawpoolwlsky.cpp +++ b/indra/newview/lldrawpoolwlsky.cpp @@ -325,6 +325,8 @@ void LLDrawPoolWLSky::renderStarsDeferred(void) const { LLGLSPipelineSkyBox gls_sky; LLGLEnable blend(GL_BLEND); + LLGLDepthTest depth_test(GL_TRUE, GL_FALSE, GL_LESS); + gGL.setSceneBlendType(LLRender::BT_ADD_WITH_ALPHA); F32 star_alpha = LLEnvironment::instance().getCurrentSky()->getStarBrightness() / 500.0f; @@ -386,6 +388,7 @@ void LLDrawPoolWLSky::renderSkyClouds(const LLVector3& camPosLocal, F32 camHeigh { if (gPipeline.canUseWindLightShaders() && gPipeline.hasRenderType(LLPipeline::RENDER_TYPE_CLOUDS) && gSky.mVOSkyp->getCloudNoiseTex()) { + LLGLDepthTest depth(GL_TRUE, GL_TRUE); LLGLEnable blend(GL_BLEND); gGL.setSceneBlendType(LLRender::BT_ALPHA); @@ -549,22 +552,21 @@ void LLDrawPoolWLSky::renderDeferred(S32 pass) if (gPipeline.canUseWindLightShaders()) { { + // Disable depth-writes for sky, but re-enable depth writes for the cloud + // rendering below so the cloud shader can write out depth for the stars to test against LLGLDepthTest depth(GL_TRUE, GL_FALSE); if (gPipeline.useAdvancedAtmospherics()) { - //LLGLSquashToFarClip far_clip(get_current_projection()); renderSkyHazeDeferred(origin, camHeightLocal); } else { - // Disable depth-test for sky, but re-enable depth writes for the cloud - // rendering below so the cloud shader can write out depth for the stars to test against - renderSkyHaze(origin, camHeightLocal); - + renderSkyHaze(origin, camHeightLocal); } renderHeavenlyBodies(); } + renderSkyClouds(origin, camHeightLocal); } gGL.setColorMask(true, true); -- cgit v1.3
