Need Help Removing Environment Reflection

Ratthew · January 17, 2022, 2:10am

I have a specific issue with Transparent film, and the Glossy BSDF.

I want to have only the reflection of the object visible, and not the environment. I turned on Transparent Glass in the Film section, but it hasn’t done anything. I’ve turned off the environment for reflections, but then the background just turns black. This is an example of the issue I’m facing. The right side is where the mirror would be, and the other side is transparent. I just can’t get the mirror to render completely transparent. (The left side is only white because it was uploaded as a PNG, but the right side is always white no matter what I do)

I’d like it to reflect the object, but NOT the Environment node I’m using, so that it looks like there’s two objects pretty much. Does anyone know if this is possible, and what I would have to do?

I still don’t understand what you mean, so what object should be transparent?

I want the mirror on the right to stop reflecting the environment texture, making it appear transparent along with the background. The end result would produce two objects on screen, one of them being the reflection of the other.

I still don’t understand, can you show me what objects should receive reflection

This is how I would like it to look,

but it comes out as this, because it reflects the environment texture.

I want to figure out how to stop the environment texture from reflecting off of it.

Which environment texture do you mean, the world environment texture or the environment texture of each object in the scene?, if you mean you mean the world environment texture just turn on transparency in rendering settings

So you do have an environment texture and want the mirror don’t reflect (mirror) it…??? So then simply turn of the environment texture (why added anyway) ??? Maybe it also would help to show your setup instead of confusing @jhon_don ?

Sadly, what he seems to want to do is to make the reflective object invisible and just make the reflections of the other objects visible, as I understood. Is there any other way to do that besides of compositing?

Mirror modifier? Actually in games mirrored objects are often just real geometry (of course mirrored).

Ratthew · January 17, 2022, 10:01pm

That’s exactly what I’m trying to do

I would’ve done this, but I’m trying to achieve the mirror look with an animation that would overlap at the center (completely ruining the mirror effect), unless you know a way around that issue.

The problem with the mirror modifier is that the mirrored image will not reproduce the light conditions of the original object as the light will not be mirrored as well.

Okay then maybe some more info about the use case of this particual “trick” would be helpful.

A mirror which don’t mirror the environment light but all the other

That’s somekind of contradictory.

Maybe two scenes with the mirror area as a mask for:

Scene 1 as the “normal” scene with environment light and mirror as simple plane or holdout?
Scene 2 with no environment for just rendereing the mirrored aread.

and just conbine those two?

so you want the mirror to reflect objects around it but not reflect the background and the mirror is transparent to the background.

as you can see the mirror reflects the object but does not reflect the background and at the same time is transparent to the background.
and in world settings you have to uncheck the glossy.

Uploading: nm.PNG…

uploading image stuck lol.

what happen?
