Make objects appear on top - always

[SpiderPig]

I think what I need is to disable depth testing but it didn't do what I expected.  The models that this material is applied to are small and are sometimes inside other objects, I just want them to be always onto of everything.

debug_point_material = CreateMaterial();
debug_point_material->SetShaderFamily(LoadShaderFamily("Shaders\\Unlit.json"));
debug_point_material->SetShadow(false);
debug_point_material->SetDepthMask(false);
debug_point_material->SetDepthTest(false);

I've had some trouble disabling depth testing. Not sure what is going on. I ended up using a second camera and rendering that on top of the scene, and had much better results with this.

[SpiderPig]

Interesting.  Is that a by-product of Vulkan or is it fixable down the track?

[Josh]

It's not enough just to disable depth testing. You have to render that object last, which means it needs to appear after all transparent objects. But then transparency has two render paths, once for conventional transparency, another for transparency with refraction. So I just haven't bothered trying to work that all out, and I'm not sure it's even worthwhile when a second camera works perfectly.

[SpiderPig]

Yeah I agree, I'll use a 2nd camera.  Thanks.

[Josh]

Yeah, and then there is the issue of ordering of multiple objects that both have depth testing disabled...the second camera is more versatile anyways.

[SpiderPig]

Yeah and Ultra seems very capable of rendering multiple cameras.
