Hi All - here and there I’ve already mentioned it in this forum, but think it’s worth to remember it again ;-)
A typical workflow, at least for me, is to use SkUp´s Photo-Match Tool. The purpose is usually to produce a location- and view corrected rendering with alpha channel, which can then (e.g. in Photoshop) be copy-pasted back into the original photo.
If possible, I love this approach because:
A: I am mostly too lazy to build any environment
B: I would not get paid to model cars, forest or any other scenery around [no matter how much I would like to do that ;)]
C: I think it is often not that wrong to show a project in the real environment.
With a little routine this process is very simple and fast then, especially when the render output is already synchronized with your used original target photo within the renderer itself - any fumbling or scaling around is not necessary.
The image below shows a bit of this process using the so well running Shaderlight Render approach, where you just have to synchronize the render resolution numerically with the resolution of your target photo.
There’s one detail to keep in mind though: Disable shadows within SketchUp so that a shadow falling to the ground doen´t get rendered by Shaderlight. Then save the rendered image as PNG, as this format already provides a transparent channel.
