Subject: Help - renders are not what's in window


ecccoman ( ) posted Fri, 01 August 2008 at 3:21 PM · edited Tue, 19 November 2024 at 2:23 PM

All of a sudden when I render the resulting image is of a very small portion of the scene in the  preview window.  I have a room with a few figures, but no matter how I set the camera I can only get renders of a very small detail in the background (a corner of the wall).  Even on 'Render Area'

No matter how I change the scene or camera angle, I get the same render.

Same for both Main and Pose cameras.

Tried changing 'point to' to - Universe. 
Tried changing 'parent' to - Universe
Render dimensions are - Match Preview Window
Camera setting seem normal

Thanks for any suggestions

I suppose it's possible that it is not rendering from "Curent" camera, but set to use another.  Not sure where the settings for that are, and you didn't mention which version you're using.  I think that would be the first thing to investigate.  I hope it's something that easy.

Can you please attach a screen capture of the actual scene that you see inside Poser, and also one of the render itself?

What do you have your render dimensions set at?  You find that under "render" in the tool bar.  Do you have it set to render a specific size or to match the scene window?

I think you are on to something, because it always seems to be looking thru another camera with a real tight focus.  Have to keep looking

I use Poser 7............ and I seem to be constantly running into issues like this.  Don't know if it is me, Poser or my rig.

Thanks

Sounds like the render is using one of those "Shadow Cam" cameras?

Not sure what a 'shadow camera' is.  Using Firefly with auto settings.  None of the 'Option' boxes on FireFly are checked.

However, I get a very good render of a very small area.

The problem is restricted to the scene.  Opened another scene and it render fine.

The shadow cam camera is a camera that in effect lets you look at what a light is
looking at.  Each light has a shadow cam associated with it.  In the camera select
they will be at the bottom of the list of cameras with a name like Shadow Cam Lite 1,
Shadow Cam Lite 2, etc.  They are useful in making sure your light is pointing at what
you want it to point at because as you move the light, the camera view follows the
light movement. So say you want to see where light 2 is pointing.  You select
Shadow Cam Lite 2.  If you don't see anything in the camera, your light isn't
pointing at anything, so you would rotate the light 2 x,y,z until the object you want
the light to point at comes into the view of your shadow light camera.

If it's just this one scene, edit the PZ3 and locate the line that begins with

useCamera

This line will tell you which camera is actually being used.

Arcadia

I get the same about result with Render Dimensions set on Match Preview or Fit in Window.

Attached is a shot of the render I keep getting.  I have no camera pointed in this direction.  In fact it is behind the camera.

As for the original preview window, I don't really know how to turn a screen capture into a simple jpeg or png.

Screen captures are easy with Irfanview.  It's free, and it's a Swiss Army Knife
for all sorts of graphic tasks.

Got the tool, did the captures, now to figure out how to attach them here.  Can't figure out how to attach 2 picture.  So will do 2 posts

This is the scene I am trying to render.

This is what gets rendered.

It is actually somewhere behind the camera.

Aha!  I recognize Sleazo's motel scene. 

I have the same scene, and I've run into the same problem.  (It's not peculiar
to Sleazo's scene; common to most four-walled scenes)

Here's the deal:  The walls of the room are one-sided surfaces, pointing inward. 
This means that Poser's cameras can look through them in Preview mode,
but can't look through them in Render mode.   What you're seeing in Render
is actually the wallpaper of the nearest wall.  In a real building you wouldn't
be able to see through the walls in any mode, so this effect is surprising
until you get used to it.

The demo image here is from my Arcade Hotel, which has similar one-sided walls.

More info:
In preview mode, the cameras see only the surfaces that are facing more or less
toward the camera.  They don't see surfaces that are facing away from the camera. 
This is convenient for setting up a four-walled scene, because you can look in from
various sides quickly without hiding and unhiding walls.

For a render, you need to either hide the nearest wall (make it invisible)
or else push the camera inside the room and adjust the focal length
and scale to get the right view.

ockham,

That was the problem and I thank you.  You saved me hours.

In graphics, a screenshot is worth far more than a thousand words.

Most of these problems are familiar when seen, but when described
only in words it's very hard to tell what's really happening.
