Photoshop 3D rendering, multiple layers

I have an image with 7 3D layers. Each of the 7 3D objects are on their own layer. If I choose to render, do I need to render each 3D layer one at a time or can they all be rendered at once?

You can do it two ways.

First way - render each layer separately. This can be useful if you want to prevent each object interacting with the others for example prevent shadows falling in neighbouring objects, or if you want to use different render settings for each layer.

Second way - select all the 3D layers and use merge 3D layers to bring them all into a single scene. Now the shadows from one object will fall on the other for a more coherent render.

The second way is more usual but the first can be useful in certain situations.

Would the rendering process more quickly if all the layers are merged?

One way to speed up rendering is to put a selection box around the area to be rendered (including any shadows) before hitting the render button. That way you don't waste CPU time rendering empty space.

Dave, This tip is a real jewel! In my particular image it made a huge difference in rendering time.

I'm just getting started with 3D. So much to learn.

I would think you would merge the 7 3d Layer into a singe 3d Layer with 7 object so all object would be in the same 3d space. If each remain is its own 3D world I would think each would be rendered one it own they are in different 3d spaces
