I'm having some issues with an animation render. Heres the problem. I'm getting a strange glow in my background. Im using a jpeg as a background then i have a picture in front with three other pictures swirling around it. Now when i rendered it the first time it look great. I used three spotlights in the scene. Did it with 5 passes with the output being a .mov file. I'm using this for a animation that goes on a web page. 227W by 247H. Then i started adding lens flare to it and some where in the lighting process i messed up. Now im getting a white glow behind the object which i want, but its leaving a green outter glow around the edges of this jpeg. Its like painting the four corners of a picture light green. The jpeg background is a backdrop like skytracer so its not on an object. I dont understand why its getting this diffrent color around the edges when the background is not even apart of the scene its part of the skytracer. Ive deleted the lights out of the scene and i get the same result. I've tried to brighten it but it also brightens the background with a brighter green. I took it into photoshop and brighten the jpeg background and that is the only thing that did help, but its too bright for the webpage. I'm just at a loss. I dont know if i clicked on a switch and messed it up or WTF i did. I've been using lightwave for a couple years now and I HAVE NEVER RAN INTO A PROBLEM LIKE THIS. SOMEONE PLEEEEESE HELP. I can redo the animation, but i want to know what happened so if i ever do run into a problem like this i know what to do.

Hard to tell what's happening without seeing it, can you post some images?

Two things in the meantime, LW doesn't like jpg's, and outputting to .mov instead of individual frames can be problematic, risky or sacrifice quality.

Yes, an image (and while i'm at it, paragraphing your text next time) might help us understand the problem better.

It could ofcourse be anything, but it looks like artifacting to me.

What format are you rendering out to? You might want to set the compression lower.

And just as a rule of thumb... Never ever use jpg's in your final renders. Jpg's are a compressed image format. When you output, eventualy you will compress your output again, thus getting compression over compression. This can give all kinds of strange effects. Use TGA's or TIF's but don't use JPG's (or any other lossy format).

yeah the orginal file got lost or screwed up. I just tweaked it in photoshop. I got a good final result tho. I'll post after i get it put online for the page. It must have got corrupted or something. That is the only explination. For now on i think ill use .tif images. Is there anyway i can reset my Layout, or do i have to??

Not making much sense. So if you disable all the lights and objects, the background image renders with a light green edge, correct?
I dont know how a background image is "part of the skytracer"? What happens when you disable Skytracer?

the .mov file will really change your way of thinking. If you render the .mov file it turns out really well.

Is this an advert for your site or something?

All I get on any of your links is a dodgy looking website belonging to Hawk Films!
