post-Process Effect

Does anyone know how I could create an effect like this? is from Sherlock Holmes The Devil’s Daughter, he uses intuition to highlight specific objects in gold as in the image. I was wondering how I could make this effect on postprocess and how to make objects / decals a highlight color !!

if someone has an equal BP and want to pass me I appreciate it !!

Custom depth maybe?
You can assign actors to use custom depth, then use it as a mask in your post-process blendable.

Or search it on youtube there are many ways to do that.

I got it, but the problem is that I can see the OBJ through the wall … do you know how to solve this?

Try comparing the depth pass with the custom depth.

Ask me a question, I saw a tutorial here in the forum of a simpler material that desaturizes the screen leaving the black and white, I did it, but did not have a comprehensive explanation, I just need my obj is not affected by post-processs how could i do this? can you tell me? thanks in advance
