Indoor Reflection not working in certain areas

So, for some reason certain areas in my ported map from unreal engine dont generate reflections at all. I checked out if its related to the object having no metallic map but even after adding it only very specific areas have the actual reflection enabled.

My lighting settings should be set up correctly for reflections. Correct me if they arent.

So far I have tried to

  • Experiment with lights.
  • Change the PBR material to be more “metallic”

If you’re looking for reflections you’d be better off working with the roughness map. Also, are you sure you’re not having reflections? If you look underneath the neon sign on the left, it’s pretty reflective.

If you look at the top image, only a small “radius” like area has reflections. The whole other area has 0 reflections for some reason. which is odd as it does capture the reflection. It just doesnt display it on the mesh?

To me it looks like you’re just looking at it from a shallow angle? Anyways, are you using a roughness map?

#5

Yes, everything is assigned. Roughness Metallic Normal and Diffuse.

#6

You could take the roughness map into photoshop, and increase the contrast. That should increase the relative strength of the reflections

Oh that’s weird, I see what you mean. Reflections only work when there’s plenty of light. Maybe you need to add some more lamps to the dim side?

#9

Will try that, let me check by expanding the range and the brightness of all the spotlights on the walls.

#10

Also make sure EnvironmentDiffuse is 1 for best PBR result

Even after I did what you have told me. The issue still happens. DiffuseScale is 1 and the lights range is 60 and Angle is 180°.

Add me to a teamcreate or send me the model, I’ll have a look

#13

Add me on roblox. Ill add you to a empty place that has only that specific part of the map.

#14

You don’t need to add me, just go into teamcreate and type in ExercitusMortem

nvm, did have to add you

#15

Added you to the empty place. You should be able to check it out now.

Skybox issue. It’s not that 1 side has less reflection, it’s that the skybox is lighting the area less. I changed the skybox and now it’s fine

#17

Checking it in the main game with the skybox has the same issue. The areas are still not generating reflections correctly.

#18

It’s definitely the skybox though

#19

How does the skybox affect EnvMap generation? I never quite understand how roblox gets their reflection probes at all

#20

Well, the skybox is the thing that’s reflected. By using a skybox that’s dimmer on one side and brighter on the other, the reflections will be different too.
