r3242 Randomly dark sectors

[Enjay]

As per this topic

Some sectors seem to be randomly having their light level set to 0. Each time you play, different sectors are affected.

To quote myself from ChronoSeth's thread...

---

It looks like a genuine enough problem. I fired up Hexen in GZdoom r1218 and got the following:









I restarted my game (without quitting) and this time all the areas that I screenshotted above were fine...



but there was a dark sector by the front door that wasn't there the previous time.



I restarted my game again and the front door and other areas were fine, but this area was black and it hadn't been on the two previous plays.



However, it is a Zdoom problem, not GZdoom. Zdoom r3242





The above areas were all dark. No flickering or anything, just dark.

My guess is something to do with the recent change to allow light levels to be set outwith the 0-255 range. [/edit]

I can confirm this too on ZDoom/Linux r3239 (and a fresh compile of GZDoom).

I noticed that third first-level run-through I did, the way to the first key room was fine, but on the way back from the key room, lots of sectors in the large room at the beginning had become dark.

With the GZDoom tests, every run seemed fine (I did 3 here also), until you start a new game without exiting, then BAM. Dark sectors all over the place. In the last GZDoom test, I saw lots of sectors go dark right before my eyes when doing things like hitting triplines and switches.

Interesting. I didn't see any sectors change during a game so I assumed they didn't. Apparently I was wrong.

It sounds like this is somehow related to the lightning effect (found on my map and MAP01 of Hexen).

Any idea what revision started having problems?

[Enjay]

I tested in r3224 and was able to find some black/dark sectors. I tried in r3222 and after 5 games I did not find any. The random nature of the bug means this isn't a definite but my guess is that my hunch about the light values outwith 0-255 change in r3223 (which I don't have a build of) being responsible may be correct.

Since it hasn't been explicitly mentioned, also know that this only happens in Hexen. Doom, Heretic, and the others are fine. For me, that is, but it seems to be the same for everyone.

Fixed. Yes, it was the lightning.
