Hi, with shader preset sometimes you want to indexe colors with an auto-generated palette instead of a static palette image.

For that, save your shader before click on import & manage.

If it's not the case, the palette will be handled as managed palette so it will saves the palette image.

Or in the shadercfg file saved you can just replace the lines (example with a palette)

palette=Object(ImageTexture,"resource_local_to_scene":false,"resource_name":"","flags":2,"storage":0,"lossy_quality":0.7,"flags":2,"image":Object(Image,"resource_local_to_scene":false,"resource_name":"","data":{
"data": PoolByteArray( 26, 28, 44, 255, 93, 39, 93, 255, 177, 62, 83, 255, 239, 125, 87, 255, 255, 205, 117, 255, 167, 240, 112, 255, 56, 183, 100, 255, 37, 113, 121, 255, 41, 54, 111, 255, 59, 93, 201, 255, 65, 166, 246, 255, 115, 239, 247, 255, 244, 244, 244, 255, 148, 176, 194, 255, 86, 108, 134, 255, 51, 60, 87, 255 ),
"format": "RGBA8",
"height": 1,
"mipmaps": false,
"width": 16
},"script":null)
,"size":Vector2( 16, 1 ),"script":null)

By

palette=false

The lines save the palette texture. If the palette is equal to false, the software will auto-generate the palette.
