Is there a way to set the scene size to a custom size other than the three choices of 30in, 30ft and 3000ft? 

Chucker

In the some 7 years I have used Carrara, I have never needed other than the standard (medium) setting.

I think, seriously, that the introduction of the other two options, and the changes that were made to the likes of some of the presets to work with them, is BY FAR the worst retrograde steps ever taken in Carraras development.

Why would anyone need even more choices ?

Now THAT will put the cat amongst the pigeons I guess!

Quote - Why would anyone need even more choices ?

Because, when I export the scene to After Effects and open in AE the scene is huge... even at the smallest scene setting.

I don't see a connection with those settings and the rendering Output Image Size?

Am I missing something?

Brian

The 30in, feet, 3000 feet are just used for scale on objects and camera movements not output.  Is AE opening it as 3d objects or as rendered output?

As X says.

There is no difference in the kb file sizes of the rendered images of any of those choices.

Brian

What the others have said already. Rendered image pixel dimensions aren't related to scene dimensions. They're under the render room settings, under the output tab.

(Scene dimensions do have their uses, but that's for more for judging the scale of objects, simulating more realistic lighting, and doing things with physics or movement.)

 I'm not talking about rendered image dimensions.  I'm talking about exporting camera, lights and scene data out of Carrara for After Effects.  When that data is brought into After Effects, the scene in After Effects (the physical space, not image size) is huge.

 I figured it out... I scaled down the size of my objects in the scene and the imported file in AE was a much better scale. Chucker

I don't think we are using the same technological language?

Brian

I didn't know AE could use 3D scene data. I thought it was just a fancy video editor along with Premiere. New one for me, but chuck that one up to inexperince with that software. I'll take note though.
