Summary0002417: -Updated- 3D floors and fog
DescriptionSo this is sort of an update to my previous ticket. Transferred fog via 3d floors doesn't work properly in Zandronum 2.1.2 or 3.0 (3.0-alpha-150819-2351 as released on the forums).

Observations from 2.1.2 and 3.0 (observations also confirmed by Abbuw)

3.0 - Software render: Fog is not shown properly and instead acts like coloured sector lighting
3.0 - Hardware render: Same as above

2.1.2 - Software render: Same as above
2.1.2 - Hardware render: Nothing shown at all. (standard sector lighting/fog)

The file used has been attached.
Steps To ReproduceNormal way of transferring fog (don't alter sector colour or anything else) using 3d floors. Doesn't matter what type it is (solid, water, non-solid etc) same results are produced.
Additional InformationNoclipping outside of the map and looking at the dummy sector from different distances shows that the fog is working correctly. The same results just aren't being transferred properly.
TagsNo tags attached.

What about GZDoom 1.8.6?

Yeah the same thing happens in GZDoom 1.8.6. looks like sector lighting.

Which GZDoom version works properly for you?

Interesting question. I tried 1.8.02 and my latest 2.1 which both produced the same result. Maybe it's something to do with the way i am creating it.

I should also point out that turning fog off in opengl doesn't change anything.

Does this mean that the latest GZDoom version doesn't work as you expect it to?

Correct, latest GZDoom produces the same results.
While searching around for similar problems i found that Graf said this:
"1. The engine cannot easily separate fog above and below a 3D-floor. The problem is not so much the actual rendering of the fog but the boundaries.
2. A sector's fade gets transferred to a blend when used in conjunction with 3D-floors."

Ok, this is not a Zandronum bug then. So I'm closing this here. If you'd like the behavior to be changed, please request this at the GZDoom forum. If GZDoom makes changes in this direction, please let me know. Then we can talk about backporting the changes to Zandronum.
