Summary

0003987: Sprite billboarding X/Y in some transfer brightness sectors renders them pitch black

Description

It appears that this is best reproduced in Transfer Brightness sectors located in map DBAB28 of eoncollection_vol-1_b1.pk3

I've attached screenshots of this issue. The only difference is the client setting of sprite billboarding. X/Y Billboarding produces the sprite being rendered pitch black. Y Billboarding brings the sprite back into beautiful red, green and blue vibrancy.

Steps To Reproduce

DBAB28 of eoncollection_vol-1_b1.pk3, transfer brightness sectors are located below the red electricity ceilings. Toggle sprite billboarding options.

Unknown if this affects all transfer brightness sectors with Zandronum 3.1

Seemingly does not affect software renderer. Issue reported while using OpenGL.

(0023143) Ru5tK1ng (updater) 2024-03-01 04:26 edited on: 2024-03-01 04:27	So interesting thing I found when testing if the action, ExtraFloor_LightOnly, was broken in GZDoom 1.9.x. Turns out it GZDoom 1.9.x just flat out crashes the map until that line special is cleared. In GZDoom 2.x.x, the blacking out doesn't occur. I have no idea what caused the regression but it'll be something to keep in mind for when Zan 4.0 comes out.
