ZDoom

With the above build, certain sprites don't get rendered and enemies may die as soon as the map starts.

Basically, it's the same as this - as reported for GZDoom - except that the map geometry rendering issues only affect OpenGL.

See my post in that thread for details of the issues that affect ZDoom.

try https://github.com/rheit/zdoom/commit/3 ... 0ea4e0bf66 , more recent than 4e683d3. It works fine for me.

OK, I just built:
ZDoom 2.8pre-408-G361341E
GZDoom G1.8.1-545-G017C919

Both seem fine. I'll take down those very broken builds to stop them causing confusion (but leave the map files in place). The autobuild system should place new builds on line soon.
