Non Deterministic Lighting in Cloud Editor

Technical Support

I am working in an AFrame project using sky segmentation and VPS. While Im working on the project the lighting changes without me changing the setting of the lights in my scene. Sometimes the lighting looks correct and other times it looks too dark. The lighting changes when the simulator is refreshed. Recording is linked. Thanks for looking.

Looks like the texture you’re using for your environment map is failing to load. Do you have a cubemap in your project?

I am attempting to use real time reflections module in this project also. I have a feeling my problem might be in that direction. Thanks for looking, @GeorgeButler

I can look into the real time reflections module, you might also consider adding a fallback cubemap just so the lighting isn’t so dark.

@GeorgeButler okay so this is only happening for objects in an AFrame Sky Layer. I am going to try some different loading techniques to see if it alleviates the problem. TLDR: objects in a Sky Scene dont always have the live camera env map applied when the experience loads. I have a demo project if you want to check it out.

Thanks I’ll let the engineering team know so they can take a look.

@GeorgeButler this is something to do with the color encoding I think. Check out this recording where I change the renderer to have LinearEncoding. After I change the encoding the sky objects and foreground objects look exactly alike. I dont know how sky scene works under the hood, but it might be missing a setting.

I’m not able to see the recording, perhaps you could upload it unlisted on YouTube so I can share it with the engineering team as well?

@GeorgeButler here you go youtube recording

I also noticed this this sky+slam template likely has the renderer colorMangemented (srgb econding) disabled for this reason A-Frame: Sky Effects + World Tracking | 8th Wall | 8th Wall
