Actor visible ONLY in a mirror/reflections ? 👌

A quick tip for Unreal Engine today, that will be useful if you want to play around reflections on water, metal, a mirror... and have an object be visible ONLY in the reflective material, otherwise invisible in the scene.
This might seem simple but I really scratched my head for some time before finding the right settings, and I didn't find much online about it. I hope this can serve as a useful resource for future creators and artists.

IMPORTANT NOTE: If you have a level sequence open and the effect is not working, despite using the settings I showed here, close and re-open your sequence. There is a bug (at least on 5.2.1) that sometimes fails to update objects' visibility. Also going with ray-traced reflections might be the best way to go about this.

The bugs make learning something so hard.

I'm making a 3D sidescroller like Little Nightmares, and I wanted a mirror to show a wall behind the player that normally wouldn't be seen, but this method doesn't work. The wall seems to vanish if the camera backs up too much.

thank you, you really helped us !

Awesome, thanks

@coulterjb22 5 месяцев назад

Thank you for this! I’ve been banging my head against a wall trying to apply a face animation to a lable. Hopefully a saved fix animation with that material can be placed on a curve to give my label a talking face.

I cannot make it work with lumen reflections, any ideas?

@vierkilau 8 месяцев назад

Would there be any way to make the opposite happen, make something not show in mirror

@CYPHERNATURE 8 месяцев назад

This is what I have been looking for. Is this only with ray tracing? Or can it be with screen beta

@alexneish5776 10 месяцев назад

Hey there. It's working for my metahuman face. But for the hair (eyebrows, fuzz, eyelashes, mustache, beard etc etc), it's not showing up. Did you have any problem with this?

@VLRN_ 10 месяцев назад

No I didn’t try this with a metahuman unfortunately. I’m guessing it has something to do with the materials, maybe the shading method

I'm looking for the inverse solution and I made it to work before and can't figure out what I did. I need a mesh to not be visible in reflection but visible otherwise.

@MrDsb 8 месяцев назад

have you found it yet?

@alphamineron 5 месяцев назад

Would love to know how

@randomancy 11 месяцев назад

That's the best mirror I have seen in unreal to date, do you have a video on making mirrors with raytracing and lumen?

@VLRN_ 11 месяцев назад

Thanks, I didn’t realize it would be interesting to show but I might do a quick video on it then :) nothing too special, it’s just a matter of finding the right settings

@randomancy 11 месяцев назад

@@VLRN_ it’s really good! I’ve always ran into issues with it only reflecting what my camera can see, and not looking like a real mirror. I would LOVE to get the right settings and follow your guide 🙂
