Instalar los Plugins de NeL para 3DS Max

• Simplemente descarga los archivos que necesitas para tu versión de 3DS Max (solo soporta x32 de momento y hasta el 2012) y copia su contenido:

• a tu directorio raíz 3DS Max.

By default the root directory is: C:\Program Files (x86)\Autodesk\3ds Max (version number)

Exporta tu modelo

• Cuando tu modelo esté listo para ser exportado usando NeL para el juego: Sólo cambia al panel *Utilities* , selecciona *More...* y en la nueva ventana que aparezca, selecciona *NeL Export* y *OK*.

• Un nuevo panel aparecera a la derecha con los Parametros de los Plugins de Nel. Asegurate de que has seleccionado tu modelo y haz click en Export model o exporta tu modelo en formato .shape.

Exportar un esqueleto

• Tienes que seleccionar el nodo raíz de tu esqueleto y clicka en *Export skeleton* en el panel de los plugins de NeL.

Exportar una animación

• Tienes que seleccionar el nodo raíz de tu esqueleto y clickar en *Export model animations* en el panel de los plugins de NeL.

SOPORTE 3DSMAX

Material de soporte

Cómo usar los lightmaps

• Usa material NeL .
• Comprueba la caja "lightmap".
• Tu material DEBE tener una textura.
• El objeto debe estar mapeado.
• Puedes mapear tu objeto dos veces usand el segundo canal de mapeo para el lightmap. (Usar CopyMap)

PUEDES:

• Lightmap se puede usar con vertex color
• Lightmap puede usarse con alpha test
• El material color difuso se utiliza.
• El material ambiente color se usa.

NO PUEDES:

• Lightmap no puede usarse con alpha vertex
• Lightmap no se puede usar con multitextura
• Lightmap no se puede usar con mapa especular
• El material color especular no se usa
• El material opacidad no se usa
• El material no se puede usar con los parametros extendidos de transparencia extendida (filtro o aditivo)

Como usar color vertex

• Mirar la muestra color vertex.max
• Usa un material NeL.
• Comprueba la caja color vertex.
• Puedes editar to color vertex con vertex paint o edit mesh.

Como usar alpha vertex

• Mirar la muestra alpha vertex.max
• Usa un material NeL.
• Comprueba la caja alpha vertex.
• Elige el canal para usar como alpha. Puedes editar to color vertex con vertex paint o edit mesh.
• Después pégalo con "CopyMap" en el canal seleccionado para alpha vertex.
• La fuente de la copia debe ser 0, el destino el canal que has escogodio en el material NeL

Como usar multitextura

Como usar textura especular

Como manejar multiples texturas para un unico material

When selecting a map, you can choose bitmap as a map type, but you can also select Nel Multi Bitmap. With a NeL multi bitmap, you can have 4 sets of maps for a single material. The 'bitmap' slot of the map isn't used anymore, it is just useful to select the currently displayed map. The 4 slots are in the 'Aditionnals bitmap' rollout. If the file name is left blank, that means that there's no map assigned for that slot. The 'Get' button allows you to choose the bitmap, and a 'View' button allows to display it

You can convert all maps in an object to 'Nel Multi Bitmap' maps by using macro script called 'ConvertMaxBitmapToNelBitmapMacroScript' It operates on the selection, and can convert materials that are either StdMat, NelMaterial, or MultiMaterial.

Once you start using Nel MultiBitmaps, you can toggle which bitmap is displayed in the viewport by using the macro scripts called SelectNelBitmapSet1..4. Sometimes you may need to refresh the display to get it work.. If a slot hasn't been defined, the first slot is taken as a default.

Note : you can also change the displayed set of texture in the object viewer, in the 'View' menu.

How to use Per-Pixel-Lighting ?

Per pixel lighting i available on GeForce 3 (and above) only for now. On other boards, gouraud shading is used instead. It is based on the blinn model. No bump is applied. Only the nearest light is rendered using p.p.l. Others are rendered using gouraud shading. (to keep single pass rendering). For now, only per instance attenuation is done.

REQUIRED: You model must have one, and only one stage of texture used (but is can use several textures) A continous mapping is needed to applied per pixel lighting techniques.

YOU CAN'T: - You can't use a mesh vertex program when this shader is used. - You can't mix shader that use a vertex program in a single model.

HOW-TO - Create a NeL Material - Select the per pixel lighting shader (with or without specular) - Apply it to your model. - Apply a mapping and a texture to your model

NeL water material

How to create nel water in Max

NeL support a form of water that can be edited in 3DS Max.

- Create a convex polygon (with z = 0 in object space) for each area of water - Apply a NeL material to this shape - Select water material

For now, full water display is only supported on GeForce 3 (though, it will run with older cards, but will look a lot less nice :( )

The following max map are used to create the water (their name may be misleading, but not all the water maps have an equivalent in max)

- Texture 1 : an environment map that is reflected by water. Basically,

 it is obtained by rendering the top hemisphere of the skydome.

- Texture 2 : May be used to set an alternate texture for the env map. - Texture 3 : the same than Texture 1, but for underwater - Texture 4 : the same than Texture 2, but for underwater - Texture 5 : here, you select a heightmap that is used to deform the envmap of the water. (the bumpmap is build from the heightmap) - Texture 6 : The same as the Texture 5, but it is used to deform the previous bumpmap (water animation) - Texture 7 : its alpha and colors are used to modulate the final color and alpha of the water

 It is then possible to blend between these 2 map for night / day transition (with the night / day dialog in the object viewer)

Texture coordinates apply only to the diffuse map. This texture may have any orientation provided this orientation is the same over the whole polygon

For the bump map, you can't specify orientation but only speed and scale (in the NeL material)

IMPORTANT: vertices between various water area should be EXACTLY welded, otherwise (big..) holes may result during the rendering.

Skinning support

• >>> The skin must be attached to the root node of the scene.
• >>> The root bone of the skeleton must be attached to the root node of the scene.
• >>> Bones must not have the same name than another node in 3dsmax.

* Bones
* Objects (like boxes)
* Biped
* Try other objects !

Animation support

Only those values are animated in the NeL engine:

INODE:

* Position
* Rotation
* Scale (in local basis only)

MATERIAL:

* Ambiant color
* Diffuse color

'Watch out:' the Bezier color controler is not supported! Use a point3 interpolation instead.

• Biped controlers are oversampled at export. They are compressed by a post process in build_gamedata

• All the bezier tang mode are supported:

* Smooth

* Step
* Fast
* Slow
* User

• The bezier "Constant Velocity" option is *not* supported.

• The loop modes supported in Bezier, TCB and linear are:
