Hi guys,
First I have to confess I’m a newbie in maxscript and I just use it for 3DS exporting (put some .3Ds in a 3D engine).
The engine is not suited for multi texturing and materials : only one texture per object.
I made a script to split all the objects of a scene, process a render to texture, save bmp file in the same directory and map the new texture. Everything work exept a UVW problem.
here is my code :
for Obj in geometry do
(
local fullFileName = “d:\ exture\ exture-exemple.bmp”
fPath=getFilenamePath fullFileName
fType=getFilenameType fullFileName
id_obj_str = id_obj as string
fName= “m” + id_obj_str
id_obj += 1
print Obj
aUVWadd = UVW_Mapping_Add()
addModifier Obj aUVWadd
print “newUnwrap”
myUnwrapUVW = UVWunwrap()
myUnwrapUVW.setMapChannel 2
print “newUnwrap added”
addModifier Obj myUnwrapUVW
select Obj
print “flatten”
myUnwrapUVW.unwrap4.flattenMapByMatID 45.0 0.02 true 0 true true
currentMapType = DiffuseMap()
currentMapType.filename=fName
currentMapType.fileType=fType
currentMapType.lightingOn = true
currentMapType.shadowsOn = true
currentMapType.outputSzX = 1024
currentMapType.outputSzY = 1024
currentMapType.targetMapSlotName=“Diffuse Color”
currentMapType.filenameUnique = true
bi = Obj.INodeBakeProperties
bi.addBakeElement currentMapType
bi.bakeChannel=2
bi.activeWidth= 1024
bi.activeHeight= 1024
finalUnwrap = myUnwrapUVW
– RTT processing
render rendertype:#bakeSelected outputwidth:1024 outputheight:1024 outputFile:(fPath+fName+fType) vfb:off
Obj.removeAllBakeElements()
Obj.bakeEnabled = false
maxOps.CollapseNode $ off
finalUnwrap.setMapChannel 2
addModifier Obj finalUnwrap
mo = standard()
mo.diffuseMap = Bitmaptexture fileName:(fPath+fName+fType)
Obj.material = mo
)
messagebox “End of procedure”
I know this is not the most beautiful script you saw
When I look to the texture editor, the texture is well mapped, but the render give me a false mapping. If I save the uvw file, delete the uvw modifier, recreate it and load the uvw file it works…
default value of unwrapp different between script and gui ???
