Editing BMD file

{{note|This page is under construction.}}

Pikmin 2 uses .json (Javascript Object Notation) files to handle the materials of its 3D models. All .bmd files in Pikmin come with a mat.json and a texheader.json. The mat.json contains the data related to the model's material, which is read by the game to produce the final model in-game. Every mat.json has the same variables that control what the model will look like.

'''Mat.json'''

{| class="wikitable sortable"

|-
| '''"TevStages"'''
| The T-E-V stands for Texture Environment Unit. It is a rendering engine that uses input sources to achieve special effects. Has several possible options, for both the Color and the Alpha. "TexColor" or "TexAlpha" uses the texture's color or alpha, respectively. "Konst" uses a Konst color. "RasColor" or "RasAlpha" uses rasturized color. "ColorPrev" or "AlphaPrev" uses the previous stage's color or alpha, respectively. "One" uses 1, "Half" uses 0.5, and "Zero" uses 0. If all inputs are set to Zero, the image will appear black in-game.
|-
| '''"ColorInA"'''
| One of the 4 color inputs. 
|-
| '''"ColorInB"'''
| One of the 4 color inputs.
|-
| '''"ColorInC"'''
| One of the 4 color inputs.
|-
| '''"ColorInD"'''
| One of the 4 color inputs.
|-
| '''"ColorOp"'''
| Short for ColorOperator, couple of different available options. "Add" makes this equation be used: ColorInD + (ColorInA + (ColorInB * ColorInA)) "Sub" is similar, except ColorInD is subtracted instead.
|-
| '''"ColorBias"'''
| A small multiplier, it has no large effect. Leaving this at "Zero" usually works fine.
|-
| '''"ColorScale"'''
| "Scale_1" multiplies the result by 1 (so nothing changes), "Scale_2" multiplies the result by 2, and "Scale_4" quadruples it. "Divide_2" divides result by 2, giving a lower value.
|-
| '''"ColorClamp"'''
|
|-
| '''"ColorRegId"'''
| The channel the result is put into. TevPrev = The final output channel. TevReg0 = first output channel. TevReg1 = second output channel. TevReg2 = third output channel.
|-
| '''"AlphaInA"'''
| One of the 4 alpha inputs.
|-
| '''"AlphaInB"'''
| One of the 4 alpha inputs.
|-
| '''"AlphaInC"'''
| One of the 4 alpha inputs.
|-
| '''"AlphaInD"'''
| One of the 4 alpha inputs.
|-
| '''"AlphaOp"'''
| Short for AlphaOperator, it uses the same options as "ColorOp".
|-
| '''"AlphaBias"'''
| A small multiplier, it has no large effect. Leaving this at "Zero" usually works fine.
|-
| '''"AlphaScale"'''
| Uses the same options as ColorScale.
|-
| '''"AlphaClamp"'''
|
|-
| '''"AlphaRegId"'''
| The channel the result is put into. Uses the same settings as "ColorRegId".
|-
| '''"SwapModes"'''
| Determines the channel that each channel will draw from. 0 = Sample from Red 1 = Sample from Green 2 = Sample from Blue 3 = Sample from Alpha.
|-
| '''"RasSel"'''
|
|-
| '''"TexSel"'''
|
|-
| '''"SwapTables"'''
|
|-
| '''"FogInfo"'''
|
|-
| '''"RangeAdjustmentTable"'''
|
|-
| '''"AlphCompare"'''
| Creates a filter based on the Alpha of the pixel that determines whether or not that pixel is rendered.
|-
| '''"Comp0"'''
|
|-
| '''"Reference0"'''
|
|-
| '''"Operation"'''
|
|-
| '''"Comp1"'''
