r621 rendering problems with Mr. Tee's demo

[Enjay]

I know that Mr. Tee has PMd you (Graf) with the location of his editing demo file. I was looking at it with GZdoom and I noticed these anomalies.

1: Translucent lines sometimes lose their texture.

These screenshots were taken one after the other. Rotating my position switches back and forth between the texture working and it not. I didn't notice the effect when I first entered the room and think that, perhaps, I need to fire my weapon or possibly look in the mirror in that room before the effect happens.





2: This polyobject on map 2 shows what I believe is called z-fighting.

If you are wondering why nothing is happening here it's because I cannot reproduce the first effect.

The second one is something that's not easy to handle and currently I have no clue what to do with it. Polyobjects that overlap with a fog boundary should generally be avoided due to these problems.

Fixed the transparent texture glitch. Since the mirror wasn't visible in your screenshot I didn't see the real cause of this: There was a decal on the mirror. Decals on mirrors are handled differently than normal decals. But the decal drawing code left the render state with a render mode that doesn't work for normal textures that followed.

(Finally. I have been scratching my head over this for quite some time and it was the last thing that delayed an official release. I think now it's time. )

Glad you got it sorted and sorry that my screeny didn't give enough clues. It must have been a bit a a eureka moment when you realised what was causing it.
