sorry for posting with out the context, we built app which combined with react, i can’t reproduce this in playground. but here is my application which is built to change the textures of 3D rooms.

https://surfacevue.com/.

we are using node material to changes the textures. suddenly some times when we change the texture once a while we are seeing the above error.

Hum, do you have any way to reproduce it?
One thing you can try is to set nodeMaterial.allowShaderHotSwapping = false
