I do a lot of custom sign design (room sponsorships, donor walls, etc), and produce 3D renderings of them composited into reference photos I take of where the sign will be installed.

The quality of materials and rendering in Adobe Dimension really has me intrigued, but I need a way to place the 3D model vertically and catch the rendered shadow as if it was set against a wall.

In other software, I create a plane with a shadow mat material to catch the shadow, which is then rendered directly on top of the reference photo set as a background image. Is there a way to achieve this in Dimension?

One option is to rotate the camera and use the ground plane to catch the shadow, but then you loose out on the image matching feature, which is really nice.

I'm doing renders and wanting to emulate a 50mm Canon FD lens that I have in my kit. It occurred to me that Lightroom has all of the details on every one of these lenses AND the distortion/vignetting that those lenses apply to the image.

Proposal:

Add lens options to the camera feature to enable us to replicate existing lenses. This would include the option of adding lens distortions (this is especially valuable in renders with high-dof where rendered objects are out of focus and near the edge of the frame where barrel distortion would change how the focus appears)
Add f-stops to the 'blur' section in order to standardize the amount of blur (and keep things grounded in reality a bit more)
Change the 'view angle' to 'lens angle' so that I can jump in and say 'cool, the photo background was shot with a 90mm lens at f5.6' etc, or 'I need to frame this with a 50mm at 1.2 to match the rest of my assets'.

So far I'm having a fantastic time with Dimension! Just daydreaming about ideal features that might not be a pile of work.

Here is the proposed workflow:
1. Select an object in Dimension that you've placed
2. Go up to File>import> 3D Object and click to start the import process
3. Imported object is set at the exact coordinates of the previously selected object, and is now the selected object in your scene.
4.You can now make minor X,Y,Z location changes to the new object in order to have it match your vision of the composition.

Current process
1. write down all of the coordinates for your currently selected object.
2. Go up to File>import> 3D Object and click to start the import process.
3. Once the 3D object has imported enter the X,Y,Z coordinates to place the object exactly where the previously selected object is located in your scene.

    If you don't manually enter the coordinates, and click on the blue dot indicating that the new 3D object is not visible in your viewport the camera will snap to it's location ruining the setup of your composition which is maddening when there's not a secondary option of multiple viewports.

I believe that this would be a much needed feature since multiple viewports are not something that you will be addressing right away.
