Can anyone explain or point to a tutorial on Motion Blur in Poser 7?  I have created a 30 frame scene with key frames in 1 and 30, with an object moving from one point to another.  With Motion Blur on in Render Settings, it only renders one frame, adding no blur.

What's the method for adding motion blur?

3d motion blur in render settings, firefly, raytracing checked, shadows; render all frames as movie (or series of images) using firefly. skip the 2d motion blur thing in movie settings. post screencap of movie settings.

Tried all the settings you mentioned and then rendering as a movie.  There is no blur in the movie, or in the images if saved as images.

The desired effect is to have some blur on an object to show movement.  Is it possible to get this with motion blur, to have an object move throughout a few frames but render that movement as a blur in one frame?

Images with settings are attached.

Here are the movie render settings.

Here is the rendered image...no blur present.  The blur is to be on the blue sphere and man, hopefully giving a feel of movement, as in a comic book.

The settings as given by Miss N do in fact work.  I took an existing animation, of my avatar jumping up and down, and turned on 2d Motion Blur in the animation settings.  Raytracing on, nothing else special. This is the third frame...

I wonder if your plasma blob is so 'noisy' and blurry to begin with,
that you can't tell when it's blurred?

I am curious myself....

Over 30 frames, how does Poser know the 'direction' from one frame to the next?

Is 3D motion blur a post-process function inside poser?

::::: Opera :::::

It does seem to be a post-process.  If you watch carefully
you can see the blur happen, during a few milliseconds after the
frame is complete.   The first frame isn't blurred, so presumably
Poser picks up frame N-1 and does a pixel-by-pixel XOR, or
something similar, with the current one.

I tried a render without blur and with it, and then compared the two.  They look exactly the same.  I'll try it with just the figure (removing the ball) to see if that's the issue.

I'll also try making the motion more extreme.

Removing the ball did not help, there was no blur.

Rendered on frame 30, that didn't change the result.  There was no blur.

Does this have to be rendered as a movie?  Even so, with both 2D in movie render and 3D in render settings, there was no blur.

The settings are those in the earlier images, that match those posted by Miss Nancy.  What is being done wrong?

flibbits, we do not think rendering one frame will show you blur.

the program has to 'remember' the location of moving items from frame to frame, and then after rendering  a given frame of the animation it does a 'post processing' treatment to the frame it just rendered.

Stick with it, the people helping are excellent, we will get it.

2D motion blur is a post process and works with every render. 3D motion blur happens at render time and is FireFly only. The two are completely independent and there's no need to use both of them simultaneously. Pick one. 3D motion blur is more expensive, but also a lot more precise. It will work correctly through transparencies and object occlusions. It simluates a real camera shutter that you can control through the shutter open/close parms of the camera. 3D motion blur will show up in a single frame and is turned on/off through the "3d motion blur" checkbox in the FireFly options. 2D motion blur needs to be applied after rendering by selectiung "Motion Blur document" in the render menu for a single frame or checking the "2D motion blur" checkbox in the movie settings when rendering a movie. In any case, if you don't see the amount of blur that you expect, chances are that there's not enough motion in the scene. If you want a single frame with a superhero showing up only as a streak across the scene, make sure that it crosses the entire scene in that one frame. If it moves only by one inch per frame, it will blur not more than one inch per frame.

That makes some sense.  I'll try it. 

That was it, moving the character across the whole screen in one frame resulted in blur.  The result isn't what I wanted, but it's blur.  Playing with shutter speed may make the effect more what is needed. 

But it may be what's needed is a few images superimposed and blurred to show the motion.

Thanks for all the help.

How does the result you got differ for what you want? Note that for larger blurs in 3d motion blur (like the streaks across the screen mentioned before) you want to increase the number of pixel samples for a smoother result.

It differs in that it looks like a blur, without the clear image clear in front of the blur. 

The desired result is more like this photo.  This is the blurred object above, with the non-blurred (rendered with 3D Blur off) on a layer above it.  Used a lighten layer with bottom layer (the blurred version) at 80% opacity.

• I wonder if there's a better way to do this in Photoshop - combine/blend two photos.

This doesn't really show as much motion as desired.  The effect should make forward motion clear in this still image.
