imported>Locke: Created page with " `EFTB` files define certain graphical effects of objects such as emissions, particles, and shaders. == EFTB File Layout == EFTB files..."

2019-09-05T03:47:23Z

Created page with "<onlyinclude> <code>EFTB</code> files define certain graphical effects of objects such as emissions, particles, and shaders. </onlyinclude> == EFTB File Layout == EFTB files..."

New page

<onlyinclude>
<code>EFTB</code> files define certain graphical effects of objects such as emissions, particles, and shaders.
</onlyinclude>

== EFTB File Layout ==
EFTB files are made up of a header and four arrays that are aligned to 16 bytes.
* Emitter Set Array
* Texture Array
* PRM{{check}} Array
* Shader Array

Each array serves as a root node in a tree structure.

== EFTB Header ==
EFTB's header is 48 bytes and is not yet well-understood.

=== Header Structure ===
{| class="wikitable"

!Size
!Data Type
!Description
|-
| 0x00

|-

|-
| colspan="4" | ...
|}

== Nodes ==
Each node in an array's tree structure is made up of a header and three optional sections.
* Binary data
* Child nodes
* Attribute nodes{{check}}

=== Node Header Structure ===
Node headers typically have the same 32-byte structure, though some are longer and some calculate certain values differently.

=== Emitter Sets (ESTA) ===
The Emitter Set Array (ESTA) contains any number of Emitter Sets (ESET), with each set containing any number of Emitters (EMTR). Emitters cause an object to cast light on surrounding surfaces. Emitters can also have any number of attribute nodes (e.g. CADP, CSDP, FCSF), the purpose of which is currently unknown.

=== Textures (TEXA) ===
The Texture Array (TEXA) contains any number of Textures (TEXR), with each texture containing a single{{check}} GX2 Texture Block (GX2B).

=== (PRMA) ===

=== Shaders (SHDA) ===
The Shader Array (SHDA) contains a single{{check}} GX2 Shader Block (SHDB).
