Issue with stationary assets in baked lighting

I’m working in this archviz project for mobile and i’m having this issue that this door, and others inside the project that are stationary assets as well, are darker than they should be, supposed to be white, and their handle which was supposed to be chrome isn’t getting propper reflections from the sphere reflection capture.
They are stationary because it’s a interactive project and i have a blueprint to make them open and close.
What should I do to make them white and their handles chrome.
I didn’t change my lights from static to stationary because i don’t want to make the project heavier.

Hello there @Immerserus!

Considering your screenshot, the reflection may be failing due a problem with blend mode. For testing, set it to Translucent. If the issue remains, please check the steps in the guide below, which happens to work with Archviz as well:

Now, for the baked light issue, if you are working with stationary assets, keep in mind that objects in that setting won’t receive proper lighting during the bake.

A good approach would be to clone those assets, and make the copies static. Do your bake using said static assets only, and once it’s done, hide the copies, and leave the movable assets on. This should result in correct lighting, while keeping the interactive doors.

I’m working with lumen completely disabled so the reflections are another thing i’m trying to solve.
My issue here is not the lighting from the environment, it is about the colour of the door, which was supposed to be white, not grey.
And also the problem of the handle of the door appearing black, without reflections from the reflection captures in the scene.
Is there anything i could do to fix these 2 problems?

stationary objects rely on the volumetric light map. in some case the probes that get interpolated can be below the surface. this leads to gradients in the lighting. change the volume resolution before baking (be aware it will have compute and volume memory storage constraints) or change the positioning of your assets.

dev note: “ShowFlag.VisualizeVolumetricLightmap 1” will show you this visualizer.

not sure what’s wrong with the chrome handle. make sure the material is properly setup. it should be white basecolor to receive the volumetric lightmap and metallic for the shine. or black with no metal and full specular. this will not handle light difference tho.
