Read this https_forum.cocosengine.org/t/cocos-creator-v3-8-6-break-astc-texture-compression/62018 (sorry, the system does not allow me to to post links)

@enj0y thanks for reply this post. I have already read this post. I have already chose option Skip Compress Texture in build option and have already tried set cache mode of label from char to none but nothing work

hungpro849 · July 14, 2025, 10:38am

still can’t find out where the error is . @Tom_k @zhangxm need some help please

Tom_k · July 16, 2025, 1:31am

The issue means shader use the cc_spriteTexture but not bound the set and binding. Could you please find which shader occurs the error, and provide the shader to us for a check.

Tom_k · July 16, 2025, 8:40am

Normally you can use layout to set the binding to cc_spriteTexture.

Hi @Tom_k thanks for reply. i finally resolve this bug. i have to custom enginge to pass this bug with if check because i got this log ‘Cannot read properties of undefined (reading ‘blendState’)’

.
I use render texture and camera use render texture to render shadow fish and fish
