Cocos Creator 3.8 Post-Process Shader Writing (2/2) Advanced

Cocos

AUGUST 16, 2023

Preface In the last article , Kylin shared how to add your own post-effect Shader in the custom render pipeline in Cocos Creator 3.8. However, based on the BlitScreen solution, we can only write the simplest post-effect Shader. Today Kylin will use Gaussian blur to demonstrate how to write a multi-pass post-effect shader.

Project: Allow undocking the Script editor and the Shader editor. For things like the Script editor, this means you can move it to another screen, move the undocked window to be side-by-side with the main window, or just using Alt+Tab to change between the main window and the undocked one.

You can now deploy your projects to all desktop platforms over SSH, as well as run a remote debug session similar to what we already offered for Android and Web. As the number of remote debug options is quite big by now, we’ve packed them neatly in a single drop-down menu ( GH-63312 , GH-70701 ). or below ( GH-69851 ).

You can also drag the material into the module’s material slot in the editor.

The node architecture with the concept of scene within scenes and the straightforward way of scripting with GDScript sealed the deal for me. I love the iterative approach of Godot to test ideas as fast as possible: import a model, create a sub-scene for it with its associated specialized scripts, hit play and iterate over.

Such pointer could be reported as valid even though the memory it points to was not, or worse, that memory could now hold a different object, leading to hard to debug situations.
