Found a solution. What I had was mostly correct, but I needed to flush the ZBuffer, then re-draw my portal triangles to the depth buffer after drawing the contents of the portal.

void RENDER_StartPolyStencil(vertexStruct* v, int n)
{
	glEnable(GL_STENCIL_TEST);
	glDepthMask(GL_TRUE);

	glStencilMask…

I'm working on screen space shadows in an OpenGL/C++ renderer, and I've been having this weird erroneous shadowing artifact. Here's a video of the artifact in action. Notice how the screen space shadows that I want to see are rendering correctly, just with a lot of artifacts on top. This means ther…

Create a depth-stencil state with DepthEnable set to false, set it on the context, and then draw your object.

I think I solved it, Instead of loading, I sampled, using float values instead of integers, then I made the depth linear which in return gave me correct values.

That fixed it. Thank you.
