Patching O3DE project
In order to have distortion particles working, PopcornFX needs to add a distortion post-effect to your Atom render pipeline:
1. Run PopcornScript/PatchProject.py,
python PatchProject.py <O3DE-source-repo-path> <
Adding effects to a scene
1. Create a PopcornFX O3DE project using the PopcornFX Editor at the root of your O3DE project.
2. Launch the O3DE Editor, add a “PopcornFX Emitter” component to an entity and choose a PopcornFX particle asset.
For correct rendering, assets used as normal map or distortion map by PopcornFX must use specific settings.
For now, those must be set by hand in O3DE. Right click on the texture asset an choose “edit texture settings”.
Pick the right setting: normal for normal maps, PopcornVectors for distortion maps.
