Sometimes when I try to render a scene, it only renders a blank screen. It goes through all of the steps, loading textures and shadow maps, ect, but at the end it's just a gray screen. It dosen't matter what settings I use and it dosen't always do it. Any ideas?

What type of scene are you attempting to render?  Could you provide a screenshot of your preview and settings.

It's hard to say when it does it.....once it was only two figures in the scene with a simple light set-up and recently it was a 5-figure scene. It doesn't matter what I set the render settings to, once it happens to a scene, it won't render no matter what I do.

I normally just re-start the scene from scratch, so I don't have any screen shots right now. I'll get one the next time it happens tho.

It could be a video card issue.  Try changing you video settings within Poser either from OpenGL to Scree or the reverse and re-render your scene.  I haven't come across this problem with my setup but others may have.  I'm just trying to narrow down the possibilities.

I wonder if you use one of the multi-camera views in the Pose Room? Whenever I start a render from one of these views I get the same thing - it goes through loading textures etc and then stops with a blank grey document window. I just switch to the full-size single camera view and restart the render, and it works fine.

If you changed the image size, your rendering may be off screen. Are there any slider adjustment bars at the bottom or to the right of render area? If so, try using them to bring the image into view.

Thanks for all of the advice....but it's none of those things.

Like I said, I never know when it's going to do it....I just know it really sucks when it happens to a scene I just spent hours setting up.

Maybe it's that darn alien implant messing me up....stoopid aliens.

Thanks again for your help....Renderosity is full of great people always willing to help someone out.
