iPhone 6 + iOS 9.3.1 + Safari 9: Transparent materials look white from far/medium distance #3

Before VR:

After VR initializes on touch event, the bush and the tree branches turn white:

Up close, the transparent things seem to look ok:

I can share out my project if you want to take a closer look (it's private)?

Thank you!

Looks to me like an engine bug rather than something specific to this library. I've raised an issue in the engine: https://github.com/playcanvas/engine/issues/573

Certainly, a simple reproducible case would be a big help. But can I ask a couple of questions:

Does this effect happen if fog is disabled?
Do you have any post effects enabled? If so, does this problem happen if you disable them?

micsun-al commented 8 years ago

Oops, I just got this to reproduce before the vrCamera engages, so I guess not related to WebVR.

Disabling fog makes the bush display correctly.

Post effects enabled, but reproduces with them disabled: bloom, brighnesscontrast, fxaa, huesaturation, sepia, vignette

I think this might be related to the particle system (I have large fog-like particles spawning in a large area around the player), but kind of shooting in the dark here.

Thank you!

@micsun-al is this still a problem, could you please give us a link to demo that replicates an issue and potentially project it self?

willeastcott commented 2 years ago

Closing because the core engine now supports WebXR and WebVR has been discontinued.
