Hi. I managed to confuse myself in setting up a render to disk bigger than the viewport. Now in trying to fix, I'm getting more confused. I do mostly print work, so I ended up with about an 18 hour render time on a project. And finally got a great render, but somehow in setting my render options I blew it with where the image is cropped. This isn't my question--I think I understand where I went wrong here and promise I won't do it again.... Question is, how can I, without redoing the whole thing, add to that render. In other words, I'd like to add about 200 pixels to the left and the bottom of this render, maintaining the same perspective. I've been messing with camera scale, which seems to let me get the bottom. And I can do a plop render of that to save me time (half the scale double the render rez I think--Bryce also freaked out doing this--doesn't seem to like zooming out with the mag glass and rendering). But I don't see how to get the left without moving the camera which will mess prespective (I think). Ugh. This make sense? Thanks for any ideas. --Snazzy

What you can do is change the degree of the Camera "Field of View" (FOV) in the camera settings. Don't forget, what Bryce is showing in the window is what you will have. Or you can render by changing the "Document Aspect Ratio" default is 4 to 3, try maybe 5 to 3? Try this and come back to me. Pleiades

Well, I think it's a little more complicated than that. FOV, would change the lens on the camera, doesn't it? So my two renders wouldn't have the same perspective. I'd be getting distortion from using a really wide lens (parralax error in photography). Likewise, if I change aspect ratios, I seem to be just getting more or less pixels with the same view, depending on if I have constrain on or off. I get that on the horizontal anyway, where I have maxed out my FOV apparently. The original render is 1500 X 864, FOV 70 degrees.

If I increase FOV closer to 90 degrees, I get everything (and then some) I want in the shot. The problem is that I am compressing my image at the same time (like zooming out). So, if this is the right track towards fixing this, what I need to know is what the relationship is between viewport/render size and FOV. I.e. for 1 degree in added FOV I need to increase the image size X. The scale button (half scale and double rez) seems to do this, sorta. Unfortunately, it seems to only help me with the bottom of the image. The other idea is to just hop over to the left with the camera--but I'm unclear if this will change perspective where the new part of the image meets old. Maybe some coffee will help.

Coffee always helps. But you can try this too.... First, Save your current render, then.... 1.Make a note of all your camera positions. 2. Hold down the spacebar and "move" your scene to the left.(cursor changes to hand) 3.Recheck your camera settings. Only one of them should be different.("Pan V" if you moved verticaly) 4.This doesn't move the camera or perspective as such, it just scrolls. 5. Do this again for the Horizontal scroll. 6. Do patch renders of your newly revealed scene. 7. I use the "export image" choice here, to save just the image file without saving over your original. 8. Have fun in Photoshop sticking the bits together! Hope this works and is clear. bigrobot

DO NOT change the FOV. That will definitely alter your perspective. As BigRobot says, you can pan the image and re-assemble it in Photoshop. This is what you're looking for. In fact, if you double-click on the Trackball, you'll get a numerical readout. Use the Pan X and Pan Y fields, along with the plop-render mode, to get what you're looking for. -flick Looking for more 3D resources? Check out 3D Commune www.3dcommune.com

Well thats all news to me! - the most likely way of re-doing without making a hash of it would be to simply re-render on another machine! - this will all be made a tad easier with Bryce 5 I hear, which has network rendering, and can tile images between several machines, even across the internet!!

Ah, if I only had another beefy machine or some sort of render farm. Actually enjoying downtime--usually render when I'm asleep. Had a fine dinner, tasty gin drink, and caught up on reading. So, Bigrobot and Flickerstreak, thanks a heck of alot for info. Scale (camera) seems to have worked fine for the bottom part of image--I think this is why that feature is there. No distortion like +FOV would have produced. In fact, same idea (I ended up with setting scale to 66.667 and render size to 1:1.5) got me most of the left side--I think. Still rendering. You're saying that pan x,y (whichever) will give me those extra 200 pix or so. If so, that's probably easier than what I'm doing, because I could have reset, smaller, the viewport just to render that part or shot it to disk. This all smells like the basis of a good tutorial. I discovered a bug doing it my way, which is this: Change scale of camera by +2/3 or double. Set render ratio to 1:1.5 or 1:2 Start a render and let go one pass Pause it Zoom out to fit Define Plop render Render that This worked for the bottom, but here's the bug: If I multitask (like I'm doing now), when I go back to bryce, the zoomed out render with the plop going on is all distorted. But! It's working fine. You just can't see it, and it looks all messed up (aspect). Like a spolied child, Bryce wants all of your attention.... Forgetting the bug, apparently the camera scale, which I never messed with before, is essentially sorta orthoginal (sp?) vs. FOV. FOV would have been a new perspective. Scale won't let me get at some areas way beyond the FOV. That's where I'll be using pan as you suggest. This is all pretty darn confusing. If I "pan" a real-life camera, like it's on a tripod, I will get a different perspective. I've been trying to imagine what happens if I jump 10 feet to the left with a camera all day--that sounds like what Bryce's "pan" does, no? --Snazzy

Change scale of camera by +2/3 or double. Oops, gin and tonic factoring... S/b: "2/3 or half"

Snazzy, Watch out for those gin & tonics! You're absolutely right on the money about the jumping 10 feet to the left or right with the camera. However,if you're able to do a standing jump 10 feet maybe the G&T's are working fine! :) bigrobot
