Lighting broken when loading the same tilesets in multiple viewers

CesiumJS
1

I created a Sandcastle.

In that sandcastle, I use 2 separate viewers, where I load the same Tilesets separately.
I expected to see the same things in both viewers, but it seems that the lighting is broken in the first viewer.

I guess this is because Cesium re-uses the tileset, maybe from a cache? How can I tell Cesium to truly duplicate the resources?

This does not happen for simple entities:

Since I load both tilesets separately, I hoped that this is not “one datasource”.

Hi @anneg, I see the issue but I’m a little stuck on the cause. Perhaps it’s related to Sandcastle? Have you tried generating the two Viewers in a non-Sandcastle app?

I’ll try to come back to this next week.

Hi @jjhembd, thanks for your answer.

Yes, I found this issue initially in my own app which uses Cesium as a library. To make sure that this is not a problem in my app, I aimed to reproduce it in the sandcastle.

Fortunately, if the tilesets for the second viewer are loaded way after the tilesets for the first viewer are loaded and added, the lighting is not broken. The webgl errors still remain, though, and they make me worry that something else might break in the short term. I would appreciate any help or tip to make sure the Framebuffer is complete.

Another user has the same issue, just error message is different. However, when I use their Sandcastle, I get the same error messages as mentioned here, so maybe different browsers produce different error messages?
