Sprite width limit in GZDoom?

[DamTheGreat]

I created a sprite for a cargo plane that is 400x64, but it shows up neither in visual mode, nor during gameplay. The actor is still there as I put a "+solid" flag on it and my movement is blocked where it is supposed to be. I assume the limit is 256, as when I make it that size it is visible, but the plane looks comically small. Is there a limit for sprite width?

I don't know what this will do for you, but the Lord Snotfolous (Cyber replacement) sprites in (the canonical) chex3.wad are 300x225 and display just fine in GZDoom 4.8.0. The difference I see is perhaps much of the left and right edges are wasted transparent space (an entire series of 300x225 sprites done with identical offsets). I guess that might be a fair next experimentation step: Go back to the 400x64 sprites, but erase much of the left and right edges so that it's a 400x64 image but most of the sides are blank, transparent area.

Another weird, potential difference might be chex3.wad's LMP sprites versus the PNG I assume you're using. I don't know why that would make a difference, but maybe try switching from one to the other to see what happens. Some other effect or flag you've set (e.g., billboarding) might also be in play.

All I know for certain is that GZDoom can display sprites with more width than 256, but that some other circumstance is obstructing yours. If there is a true limit, or if it accounts for transparent sides, I wouldn't know.

Might want to double-check GrabPNG or SLADE to make sure the sprite offset is correct on the big version.

Thank you! That was it! The offsets were way off...
