Backface Culling
-
Sorry, perhaps not explaining it well.
I've managed (after great frustration) to get a screenshot of my issue.
Hopefully this gives some clarification.
Thank you for your effort so far!

That clarifies what you are asking for. I have to think on it a bit.

Model the hearth, recess and fire, all placed in a large vertical wall face that stretches beyond the camera edges in all directions.
Do not model a floor face.
Paint the wall white.
Set the camera details to match the real photo image.
Adjust the shadows to match the real photo image.
Export the model's view as a PNG image.
Edit that PNG image [using Photshop, Gimp etc]
Set up a transparent layer for it.
Use the magic-wand to select and delete the wall face areas.
Now you have a cutout of the fire/recess with no wall, seemingly extending back into the wall.
Add this edited fire/recess image, on a layer over the top of the real photo image.
Adjust its size and location to show the fire/recess seemingly added to the 'real' photo.
Export the combo-image and the fire/recess will appear to be properly set into the existing wall... -
Thanks TIG,
That's what I've been doing up until now, but had hoped with Sketchup's App with AR function I could implement this 'live'.
I did have a play with Unity and Vuforia, but this requires a reference image.
I'm basically spending too much time providing bespoke drawings for customers and would like to give an impression of the fire in their home.
Thank you.

How about modeling the wall, and projecting the photo to the wall face as a texture?

Would there be a way with multiple sections? I'm under the impression you can only have one section at a time. Can you have section cuts within Components?
-
This may be down to my bad description, but to further complicate matters, I have different stoves, surrounds, hearths etc on different layers in order to show various options.
Projection may look weird unless you're standing in the right spot.
Good idea though.

The hitch in the giddyup is that you are using an AR setup to allow the client to look at the modifcation from different angles. Is that correct? If so, these suggestions such as modeling the whole wall and projecting an image aren't all that workable.
I think the big thing right now, anyway, is that the AR stuff works well enough if the model is in the middle of the room where all of the real stuff is background. It's not very good for models that have to go through the background wall.

I'm not sure if it would help in this situation but you can place section cuts inside components so they only affect that component. And you can then have multiple section cuts displayed simultaneously.

You're spot on with what you say.
Middle of the floor, not a problem. Free standing stoves are ideal.
The ideal solution would be a feature where I can apply a material to the wall around the stove (my mask) and for Sketchup to ignore everything behind it. I'm assuming this isn't something that could be achieved via a plugin?
It might be easier to go back to Unity and see what I can do there.
Thank you all for your suggestions.
Kindest regards,
Reagan.
