Is there a way to maintain the aspect ratio of a picture being put on a mega tree with pixels. For instance if I apply a picture of a face to my mega tree using the peekaboo it squeezes the picture at the top. Same thing applies two scrolling text it starts looking like the intro to Star Wars if I have the text set to go up

A tree is a matrix. All models are a matrix. The 'tree' in xlights is just a matrix with the verticals visually pinched together at the top.
So you're asking for an image to distort to the shape of the tree so that it visually does not change it's shape.
You could do that with Photoshop using the skew function. The image would not look correct on the tree until it was in the proper position.
-
Yeah just take the photo into Photoshop and skew/distort the top so that it's wider by the ratio of your tree and then clip the sides back to the width at the bottom. That will at least give you an idea of how terrible it's probably going to look.
-
But, if instead of just an "UP" direction, it did a "Perspective UP" like the original StarWars intro graphics, maybe it could do like he wants.
-
It's not a big deal and I can live with it the way it is I was just hoping there was a way to correct for some of the distortion. The only way I could think of was a purposely distorted custom model Matrix running as a proxy. But I think there would be way too much effort with very little gain if that would have even worked at all
-
Sorry but someone needs to be willing to do this manually by manipulating the image and show me the benefit before I'd take the time to write code to stretch the image. I'm not sure if you all realize the top part of the image would lose 300% resolution on a 3:1 tree to do what you want. You can alter the image yourself the same way we would do in software so if you really want to see what it looks like do it.
-
Fair enough. I'm guessing I'm not the first one to mention this :o
-
The problem is most people with the idea can't think it through to know what it would really mean. Mainly that you cannot do what you want and have it look correct all the way around the tree. You would have to pick which angle to want to be correct because there will only be one viewpoint that's not messed up once you start distorting the image. That's why I say try it manually cause you'll probably find you don't like it.

Have you tried changing the rendering mode to "as per preview"?
That might be close enough
