I'm trying to create a "blade blur" prop for motokamishii's ReiSen 21 model, but am having no luck. I've read (and re-read and re-re-read) Bazze's tutorial, followed (or so I thought) all the steps, but when I render is Poser, all I get is a solid colored disc. The object that I'm applying both the color and alpha maps to is a circular .obj that was created in RealSoft3D and smoothed so that it has no hard edges. I've made sure that when I plug my alpha image into the Transparency node that it is set to 1.000 and the image map is set to Alpha. Should the background color for that be something other than white? Is 75% gray for my color map the wrong gray? Should I set my color map to something other than 1.000? Any help would be greatly appreciated.

Can you post a screenshot of your render and your material room settings?  They'd help immensely. 

It sounds like you did not UV map your OBJ file. If no texture coordinates, it can't see map and only uses diffuse color

A mapping problem for sure. Poser does have problem with long thin polygons, but object does not need to be round.
Since you are using a transmap, the object can be square, the not needed parts will be masked out.
Your image is square anyway, there no round JPEG's.

I gather you are just taking picture of propellor and applying radial blur to it in a 2D program like Photoshop.

You can apply the images to the "one-sided square" primitive in poser and not have to make object.

Thank you, Medzinatar. You are correct, that's exactly what I'm doing. I'll try using the "one-sided square".

 You also need to set the Transparency edge setting. Start at .9 and adjust to your taste. The nearer to 1 you get the more transparent it will become.

An even better solution might be to make use of Poser's "3D Motion Blur" feature to actually blur the prop models in the render....just a thought.

Props spin too fast for that to be a realistic option.

Depends on how many rotations you make do - it shouldn't just move a little of course, but with a large spin-degree, it'll look pretty good.

here's an example:

and the animated version:

...what she said.  And rendered.

Thanks to everybody for their suggestions. It's going to be a while now before I can get back to it, however. Again, much thanks to all!

trekkie's fan looks good IMVHO.
what I would like for poser 9 is motion blur rendering that adds a specified number of
blur frames between each still frame.  blurring every frame is not in accord with real
video, where some of the frames are sharp, but most are blurred.

Have they fixed the rendering issue with motion blur causing transparencies to render as white squares that was seen in Poser 5? I haven't played with it yet in P8.
