View Full Version : Where is my alpha channel?

09 September 2003, 07:27 AM
For some reason Lightwave has decided it does not want to render an alpha channel. Whenever I try, the alpha is blank white. Does anybody know what's causing this?

Can you post a pic of what you are rendering? Does it have full screen refactions or anything? Do you have a full screen object with the Alpha Channel set to a constant value? That would over ride transparency I think. Only ideas off hand...

Post screen cap of ur render options.

Do you have Raytrace Transparency turned on?

It could be the Constant Value in the Adance Options on Surface Editor, u could had change it for whatever reason.

Do you have a large polygon behind everything with your background projected on it? That'll kill your alpha.

Ok, I got it, webfox was right. I thought that might be the problem initially but when I deleted the big polygon, I guess LW wasn't updating the scene, so I thought it might've been something else after that. Thanks though, the comments helped persuade me I'm not crazy!
