Two identically colored meshes don't look the same

Howdy fellow developers,

I’ve been recreating Frank’s Commissioner office from the TV series called “Blue Bloods”, however as I was making the doors and its handles, I noticed that they don’t look the same, color wise.

Keep in mind both of them have exactly the same color, and I am also not using custom PBR or a custom texture on it.

Here’s what it looks like when I have it in the office;

And here’s what it looks like when I move it out of the office;

I assume this is caused by lighting however I don’t really have any special hacks to bypass a limitation, only point and spotlights.

Thank you if any of you have a clue of what this could be.

EDIT
I also noticed that it’s fixed when you are on the lowest graphics.

This happens often to me. I have a neutral lit grayboxed baseplate where I do my mesh imports and model assembly and the color/appearance is uniform.

When I take anything from there into any other build though, I do get issues and especially with metal. Skybox/lighting/atmosphere cause that effect for me depending on their various settings. In cases where it is very obvious I’ll switch to surface appearance instead of materials.

What is the render fidelity at?

Both are set to automatic. It doesn’t change when I set it to precise.

Then this is probalby something to do with future lighting. You could try adjusting the light

What exactly could I adjust?

I don’t know you can try and adjust the brightness or range

I disabled all the lights in the room and still got the same result. It only gets fixed when I move the doors into the outside world with nothing surrounding it.

I tried that, and it still doesn’t work

Do you see any difference if you change diffuse/specular settings and color shift top/bottom?

I’m curious to see if diffuse/specular at 0,0 looks different on those pieces than if you have them at 1,1 (or any positive value).

Another thing to try would be toggling global shadows on/off to see how that affects it. I would guess turning them off would make them look like they do if you have them facing outside.

try turning castshadows off on some parts casting shadows onto the door

Alright, so it looks like changing the diffuse/specular value to 0 fixes the issue, however there must be a way to fix this, right?

Setting the diffuse/specular value to 0 gets rid of some beautiful light reflections and messes up my outside buildings:

It makes quite the difference.

This might sound like a strange request, but I wonder if trying a clear sky with spec/diffuse settings on might help? You can also try .5 vs 1 for each setting, and neutral values for top/bottom colorshift and see if that helps keep the effect you want. There are a lot out there on the marketplace, so you have a lot to choose from but this one is rated well:

Realistic Clear Sky

That’s exactly the skybox I’m using coincidentally :joy:

#14

Do you have dynamic clouds added to your terrain? I know clouds have density but I’m not sure if they affect lighting or not. Trying to narrow down any possibilities.

I did forget to mention brightness in the lighting properties. Maybe try low brightness + minimal specular and/or diffuse?

Oh, and for skyboxes - does this effect you are seeing happen with any skybox you are using?

I decided to screw it and remake them from scratch, it’s fixed now.

Thank you for your dedication either way.
