The issue when using ClippingCollection and Explixit Rendering

CesiumJS
1

Hi all,
I am writing an application that allows user clip model. I have used Explicit Rendering to improve performance. However, when I create ClippingPlane to clip model and zoom it will throw the bug as the video below.

I realize that If I turn off Explicit Rendering then create ClippingPlane, it will work well.

I want to clip model within enable Explicit Rendering. Do you know the root core of the problem ?
This is the error message in the first video:

DeveloperError: This object was destroyed, i.e., destroy() was called.

Sometime, It raises another error message:

Hi @Hung, sorry you’re having issues rendering.

Would you be able to share a minimal Sandcastle example that reproduces the error? That will help us track it down and test later if we find a bug to fix.

Hi @jjspace ,
Apologies for my delayed response. I have found the root cause of the problem. It occurs when I enable requestRenderMode as true, set pickTranslucentDepth to true, and use the clipping feature. Please check the example: https://s.net.vn/FQlm
