# Overrides
Overrides are default parameters and values which can be automatically activated when the brush is loaded.
Overrides are accessible in the panel "Details". All modifiers (size, flow, step, blend, alpha - but colors)
can be programmed to override previous ILIAD configuration. To do so, boxes on the left must be checked.
If they are not checked, it means the loaded Odyssey brush will use the same parameters as the previous brush.
Please note for people using ILIAD 0.6 and below :
Overrides shall only be changed in the Odyssey Brush Blueprint.
Even if Overrides can be visible on ILIAD interface, it is useless to change them here.
Overrides are active only when the Odyssey Brush is loaded, which means Overrides must be changed in the
Odyssey Brush Blueprint to be compiled and saved.
