Hi everyone, so I did this camera projection with Fspy, and then added objects to try and match them with the lighting of the image, but there is a problem:
The Objects don’t cast any shadows into the ground, I tried activating the shadow catcher option, but that results in the mesh with the image textured into it to dissapear, any advise?
All lights are disabled.
Not all of them, I had one activated, the one that is reflecting into the monkey, Even if they are activated, there is no shadow casted into the ground, that’s the problem.
Are you using EEVEE? Have you tried it with Cycles?
If you can release it, please share the file.
The capacity that can be attached here is 5mb, and for sizes larger than that, you need to store it outside and attach the link.
Yep, I’m using Cycles.
Everything seems to work just fine, just that little detail concerning the lack of shadows, makes the objects look completely out of place and artificial.
I think the problem is that the image material surface projected onto the meshes is put as Background, if I put the material surface as diffuse it looks preety cool, but ceases to respect the lighting of the image, is there a way to fix this?
I’ll see if I can upload the file later, thanks a lot for your responses!
have you tried to model the walls/ceiling as a simple cylinder and camera project the image onto it using a emission shader ? that way you would have the lights in the right place and could use that to light the monkey. The problem is that you seem to have just a light above the monkey and the ground should reflect light back onto it. You could also use compify addon, which does exactly that.
You’re trying to get an image straight from render, there’s a compositing stage. This tutorial explained with details.

Thank you all! I will try everything!!
Just in case: I want the camera to move, so it won’t be a still image, I want to show the 3D space, and in it, put on a rig I made and animate it there, I don´t know if the process is still the same if this the case?
you can use camera projection, if you dont move the camera too much. just try it in the viewport.
Please refer to the video
Did some testing and reflection works far better now, but he connected the image without a shader and you do need one for a shadow catcher. Very cool tutorial. Thank you!
