Describe the bug?
The ZTest within several materials does not seem to behave as one would expect. Certain modes such as LessOrEqual, and Always seem fine, however every other mode does not.
Relevant issues
(none)
To Reproduce
The test setup is a PBSMetallic Box which overlaps halfway on a sphere with a UI_UnlitMaterial applied described similar to how Zyzyl tested in discord. This can be tested with any combination of materials that support ZTest with the same result as below:
Expected behavior
ZTest should normally behave as follows:
LessOrEqual - The object testing should be drawn if the Z buffer value is less than or equal to its current z value (normal occlusion)GreaterOrEqual - The object testing should be drawn if the Z buffer value is greater than or equal to its current z value (draw only when behind objects or overlapping exactly)Equal - The object testing should only be drawn when the Z buffer value is exactly equal to its current z value (draw on the edges of intersections)Not Equal - The object testing should be drawn when the Z buffer value is not equal to its current z value (draw wherever there is not an intersection)Always - The object testing is always drawn no matter what (ignore z values)Less - The object testing is only drawn when the Z buffer value is strictly less than its current z value (only when completely in front)Greater - The object testing is only drawn when the Z buffer value is strictly greater than its current z value (only when completely behind)
