When i move camera,the transparency is strange?

i dont konw why,i just rotate the camera,but different tansparency appeared,if i move quickly,the transparency is not smooth.By the way, the roof‘s transparency looks different from wall,is that normal?

It’s an interaction with the ground created by createDefaultEnvironment.

As all elements are transparent, they are rendered in a depth sort order. Depending on your camera view, the ground is considered farther or nearer than some elements in the scene, so will be displayed before/after those elements, changing the apparence.

If you disable creating the ground, you will see there are no problems:


oh! It works.
Thank you! :grinning:
