Title: Planet Graphics Glitch?
Post by: Nix on May 24, 2004, 02:47:15 am

Forgive me if this has been posted before, but I seem to be having a strange problem with planet backgrounds being rendered.  I'm usually playing a mod using the latest mediavp with no additional graphics or resource packages, for example, Homesick and the 3.6 MediaVP.  Whenever I fly in the direction of a planet, sometimes it looks like it's segmented, or looks like it's pinched in the middle.  This doesnt happen all of the time, sometimes the planets are rendered as round spheres, where sometimes they look like these. I've attached a really crude drawing of what the planets look like, as I am not at my computer with FS2_Open on it to do an in-game screenshot.

Currently I'm running the latest mediaVP that was released this month, and using the 04-05-2004 build of FS2_Open, running my mods in seperate folders.
Has anyone else encountered this problem, and may know how to correct it? or is it a bug that's already known and I'm posting old news?

hmmm...

this should be in the SCP forum... yeah...

anyway, try this (http://www.hard-light.net/forums/index.php/topic,23779.0.html) build, I reworked the way planets are rendered so it may have fixed this, or may have made it infinitely worse, if we don't hear from you for a while I'll assume it was the later.

Really, this was in original FS2?  I dunno, never really seen anything blatantly distorted like this.  Stay tuned for screenshots and such.  I shall try this new build out now that I have a little free time.

What command lines are you using?

This is there since FS2retail. It comes from the low-poly skybox used to map the backgrounds on AFAIK. You only get to see the problem if you use really large planets thar are mapped onto a lot of polygons. It gets noticeably worse if the bitmap is low-res.

Not sure how, or if, this is fixable.

There's some option in FRED IIRC that deals with the "tiling" of background elements - that could solve such issue.

Than again I don't really FRED, but it's worth a try.

That's not about the shape. It can end up with some weird results, but that is not that.

Gads, work and real life take all my time now that school's out.

Anyway, these screenshots were taken while playing Sol: A History, which I dont know if this might have something to do with these anomalies, but here we go for screenshots.
Probably unfixable, but it was odd, strange that something like this would happen.  
Commandline parameters used:

-glow -pcx32 -jpgtga -d3d_no_vsync -d3dmipmap -fps -phreak -allslev -mod InfernoR1

I'm pretty sure that's a divisions problem - fiddle with them in the BG editor - if they're high, drop 'em low, or vice versa.

Can I see what your BG editor says about the suspicious planets?
