Archetype Flags

Archetype flags are used to define certain properties of the archetype, like its vertex colours and its physics and how it renders

Flag	Description
Wet Road Reflection	Contributes to reflections on wet road surfaces
Dont Fade	The entity does not fade with distance, it pops in and out instead
Draw Last	Drawn after everything else, so transparent surfaces such as glass blend correctly over what is behind them
Climbable By AI	Peds may climb over it
Suppress HD TXDs	High detail texture dictionaries are never streamed in, useful for props never seen close up
Static	Freezes the entity and disables physics, the default for most map props
Disable alpha sorting	Changes how the entity is written to the depth buffer, can help or hurt when transparent surfaces overlap; try it alongside Draw Last
Tough For Bullets	Bullets neither penetrate nor scar the surface
Is Generic	Appears to mark archetypes reused across many locations, poorly understood (used for procedural objects)
Has Anim (YCD)	The archetype has an associated clip dictionary
UV anims (YCD)	The archetype has UV animations, used for scrolling signs and conveyor belts
Shadow Only	The entity is invisible but still casts a shadow, commonly used to fake shadows cheaply
Damage Model	The archetype has a damaged state, as street lights and hydrants do
Dont Cast Shadows	The entity is visible but casts no shadow
Cast Texture Shadows	Related to alpha-aware shadows, but its effect is unclear. Has Alpha Shadow appears to be the flag that actually drives them
Dont Collide With Flyer	Aircraft pass straight through
Double-sided rendering	Back faces are rendered too, commonly used on foliage
Dynamic	The entity is simulated by physics and can be pushed or knocked over
Override Physics Bounds	Uses the collision bounds defined on the archetype instead of those embedded in the model
Auto Start Anim	The animation plays on its own, without a script starting it
Has Pre Reflected Water Proxy	Has a simplified version prepared for water reflections
Has Drawable Proxy For Water Reflections	The water reflection proxy is a separate drawable
Does Not Provide AI Cover	Peds will not take cover behind it
Does Not Provide Player Cover	The player cannot take cover behind it
Is Ladder Deprecated	Legacy ladder flag, no longer used
Has Cloth	The model contains simulated cloth
Enable Door Physics	Enables door physics, the archetype's special attribute must also be set to the kind of door, otherwise the flag does nothing.
Is Fixed For Navigation	The object is already part of the navigation mesh, so peds do not steer around it at runtime
Dont Avoid By Peds	Peds do not steer around it while pathfinding, collision still applies
Use Ambient Scale	Takes the ambient lighting scale from the surrounding area instead of computing its own
Is Debug	Appears to mark development-only content, poorly understood
Has Alpha Shadow	The archetype casts an alpha-aware shadow
