Hi there When using a background image lets say 1024x768.. It looks OK in preview window... It renders OK in P4 render,nicely full in background. But now here it comes... In firefly render is wrong, dead wrong. It becomes Square !?!? compressed to the middle of the screen. And the rest is filled with the background color..... Is it me again that makes a error or is it poser again ? Anyone has a clue what wrong with it. I try lots of different things but notting makes it work the way i want it. Thnx Chris

It's a bug.

Ditto. and a pita. Best to scale the bg in paint to exact size.

hmm..wonder about that. I did an 800hx600w background for the last pic in Bryce, everything's lined up and looking right, brought it in as a background, and Poser 4 tries to resize the puppy. Got it as close to 600x800 as I could, but then get a lot of pixelation and 'stair stepping'..wonder if that could be the same thing..;) @#$ thing wouldn't let me actually choose 600x800..go figure..;)

You could always use the high-res square, apply your background image to it, and use it as a backdrop. (Which is how we used to get around the "Poser renders background images really pixelated" problem in Poser 4.)

If you have the IC3 you can put your background pic on that and scale it to suit!

hmmm..good ta know..thanks..

I don't have the problem. I bring in a background that may be larger than my work area, Poser (5) only resizes the render settings, which I can easily change back. For example, I bring in a 1600x1200 background, then change my render options back to 1024x768, renders just fine.

It's a P6 exclusive. I just went through this again. Fixed it but clicked on too many variables to remember...#p

It HAS happened to me before in P5, but not lately, don't know why. Maybe because the background image is bigger than the work area. Or, it might be because you're rendering to a different aspect ratio than the background image, e.g. 1024x768 is 4:3, and 600x800 is what 3:4?

It's a memory thing, I think. If you're rendering very large, you'll have this problem. Exactly where you run into it may depend on your system memory.

I don't think so, I've rendered large and small. I think it's the aspect ratio.

It's not the aspect ratio. Not the bug Bartworx is referring to. It's a bug that appears when you render very large.

Note that it rendered fine in P4. If it was the aspect ratio, he'd have the same problem in P4 as in P6.

I just did a test. I imported a 1600x1200 background picture, and then rendered at 600x800, and the background maintained its own aspect ratio of 4:3, so the render had background grey above and below the background image which was squarely in the middle, like a letterbox movie.

Then tried changing the options to 800x600, and rerendered. Now the background had the sides open to the grey instead of the top and bottom.
And now it stays that way and probably will until I close and re-open poser.

Since Bart didn't say how large he was rendering we don't know. I don't think he was saying P4, as much as the P4 render engine. Then he said Firefly, not P6, so...

I still disagree that it's memory, I can render nice and large and it won't matter as long as I keep the aspect ratio the same for that session.

If you're using Poser 5, you've never seen the "background bug."

I've used 5 and 4, they act the same with respect to backgrounds in my experience. Anyway, I tried. We still don't know if he's using P6, he didn't say, he only said "firefly".

Okay, I think I remembered what the fix for this was. You have to make sure your maximum texture size is larger than your image. In render settings.

Thanks randym That was it.

Oke thnx for the input I used a 1024x768 backGr. and render it at 1024x768 I have 3GB mem. so thats not the problem. The image work fine in p6 at P4 rendering. I played around a while and found out that it is a bit of Hit 'n Mis with it. Once in a while its A' OK render with the back in the right size. But the when nothing has changed by me " just clik Render again" ... Its dead wrong again... so Now i know i did nothing wrong... Its a Hickup in P6 for shure ... THNX antway U all for the input !! Chris "Not BART" :}

Are you using the automatic render settings? If so, try switching to manual. Then set your Max. Texture Size as large or larger than the size of your final render.

I try to avoid using the background if at all possible. It seems to be very problematic, both in P5 and P6.

Instead, if I really need to use a BG pic, I use a 1-sided square, size it to EXACTLY the same dimensions as the pic, apply the pic to ambient, set everything else to 0 (black), ensure "cast no shadows", send the square waaaay back in Z then scale the square so everything is covered. It's a little more work, but seems more reliable.
And, although it's a little more work, for me, for the majority of times, it is quicker than coping with the BG's foibles...

The only problem I've encountered with this approach is if I need the scene to be lit from behind (ie. light in front of the camera: silhouette-type pics). There's no way to get an infinite light to shine through a square with a pic applied... (unless someone more knowledgable can tell me different -> insert "hope" emoticon)..

Cheers,
Diolma
