Are there any extra environments and backplate samples I would use for different applications such as small parts for office
The available scenes are good for vehicles or large parts?

When done incorrectly, your part will look like it's floating in space.
I've tried and my model is floating in space. What's the best way to fix this problem?
Not sure if this helps, but try checking the 'Flatten Floor' checkbox on the active HDR.
Also, you can toggle the 'Show Grid' checkbox in the active HDR, which shows the perspective lines. This will help you match perspective to your backplate.
re-adjusted them a couple thousand times
Thank you, Brian. I tried and nothing came out positive
As Rich mentioned, there will be thousands of "trial and error" before having it looked right.
The real key to make them not look floating is to find an HDR that produces the exact same shadow as in the desired backplate. This is where HDRs with matching backplates are key. This will help 'plant' the CAD onto the backplate.
I will be uploading 25 more HDRs and matching backplates before the close of the year. Also, you can try this for more free HDRs:
Yeah. You really can't fake this very well without a lot of work...
As Brian said, the pro's will create backplates (with known camera locations and camera settings) at the very same time they capture the HDR itself. This is the only way to guarantee you have lighting/shadowing that matches the environment and the camera information to frame the object using correct perspective.
If you have a high enough resolution HDR, you can fake this OK with the Flatten Floor option.
You can try Public Domain 2D HDR Maps as well.

I've made my own backplates, but their application is not easy. You'd have to know in advance exactly what your scene is to look like, photograph it, then carefully render your model into your scene. You may even need to construct an environment that duplicates your scene's lighting. My example below would perhaps be a lot like yours; placing a hand-sized product in a typical office-like environment. In my case, I'm putting some flanges on a lab cart in a room with crappy fluorescent lighting.
1) To create your backplate, take a photo of your setting and adjust it (photoshop) until you like it:
2) Insert your backplate into your render project. Now comes the hard part: adjusting perspective, camera angle, and shadows. Here, I've rendered a number of stainless steel vacuum flanges, and tilted, rotated, bent, turned, scaled, re-tilted again, and re-adjusted them a couple thousand times more such that their perspective matches that of the other parts.
3) When done incorrectly, your part will look like it's floating in space. Also note how bogus the reflections are; they accurately reflect off one another....but do not reflect the backplate. The best I can do at this point is to remove the reflections and simply add correctly aligned (and consistent) floor shadowing and just call it a learning experience!
Hope that helps!
