The game engine I work with at my day job uses vertex colours for all lighting.
We calculate the radiosity solution in Max, bake this into the vertex colour
chanel using the "Assing Vertex Colors" util, export, and everything works fine
. Mind you, this works fine on PS2 and X-Box, but I can't see why a similar
system can't be used for Director.

dunno anout radiousity (i'd like to see THAT done with vertex colors!) but
Noisecrime did an excellent demo with vertexColors
http://www.noisecrime.com/develop/techdemo/d85/lightmapping/vertexlighting5
.htm
i haven't tried, but I suspect that max will export vertex colors (it makes
them np).
one caveat, you loose the blend in your texture once you set your colorList
to anything other than [].
colorList = numColors.count. It's a set colors made available as
vertexColors to the MR.

Hi all,
I have seen many posts/requests about vertex colours in Dir3D, whats the
deal???
I pretty much thought that Dir3D couldn't display vertex colour data at all
until I came across the definition for newMesh:
member(whichCastmember).newMesh(name, numFaces, numVertices, numNormals,
numColors, numTextureCoordinates)
Where numColors:
numColors is the optional total number of colors used by all the faces. A
color may be shared
by more than one face. You can specify a color for each corner of each face
. Specify colors for
smooth color gradation effects. Enter 0 or omit this argument to get
default white color per
face corner.
Has anyone used vertex colours in Dir to display radiosity solutions etc??
Is the problem with using vertex colours that the W3D exporter does not export
the colours?
Tnk,
GM
