use material plugin, and SSAO SSAO work, but material plugin not working

What’s the difference between them? @Evgeni_Popov
You inject your code too late in the fragment shader, you should inject it at the “CUSTOM_FRAGMENT_BEFORE_FRAGCOLOR” tag and update the finalColor property:

This way, the updated color will correctly be taken into account by the pre-pass renderer.
