The custom '''material''' extension was developed by THQ to attach geometric rendering properties to a material, using alpha referencing, z-test flags, blend functions, and culling, used for the known game ''[[wikipedia:Jimmy Neutron: Attack of the Twonkies|Jimmy Neutron: Attack of the Twonkies]]''.

'''Atomic''' is a container section used in [[model file|DFF files]] as child of a [[Clump (RW Section)|Clump]] section. It is normally accompanied by a [[Struct (RW Section)#Atomic|Struct]] section. An atomic section can associate a [[Frame (RW Section)|Frame]] with a [[Geometry (RW Section)|Geometry]].

Atomics are - generally speaking - converted to draw-calls directly. They therefor resemble parts of the geometry (sub-geometries) that should be rendered "as one", utilizing a certain rendering pipeline. They are transformed from object-space directly or indirectly based on the transformation rules that are set for the Frame.

==Structure==
An atomic section contains Struct, Geometry (optional) and Extension sections.
A Struct section has 16 bytes in size (may be different in some RW versions).
struct rwAtomicStruct
{
unsigned int frameIndex; // zero-based index
unsigned int geometryIndex; // zero-based index
unsigned int flags;
unsigned int unused; // sets to 0 by default
};

'''Flags'''

There are only 2 options available:
0x01 rpATOMICCOLLISIONTEST - A generic collision flag to indicate that the atomic should be considered in collision tests.
It wasn't used in GTA games since they don't use RW collision system.
0x04 rpATOMICRENDER - The atomic is rendered if it is in the view frustum. It's set to TRUE for all models by default.

==Child Sections==
*[[Geometry (RW Section)|Geometry]] - optional. A geometry linked to this atomic and stored internally. It may exist only if [[Clump (RW Section)|Clump]]'s [[Geometry List (RW Section)|Geometry List]] is empty.

==Extension==
*[[Right To Render (RW Section)|Right To Render]] - optional. Used for Skin Rights or/and Normal Map Rights.
*[[Particles PLG (RW Section)|Particles PLG]] - optional. Used for built-in Renderware particles.
*[[Pipeline Set (RW Section)|Pipeline Set]] - optional. Used to set up atomic's custom rendering pipeline.
*[[User Data PLG (RW Section)|User Data PLG]] - optional. Used for custom rendering properties based on the given title.
*[[Material Effects PLG (RW Section)|Material Effects PLG]] - optional. Determines if atomic uses MatFx effects and thus must be rendered via MatFx rendering pipeline.
