Agust�n,
Not sure why it doesn't work in your example, but you don't have to add the
meshDeform and textureLayer if you just want to stick another texture in one
of the textureLayers. Try taking those calls out and it should work:
on addSeams scene
--loop through the 3 models
repeat with modelNum = 1 to scene.model.count
modelRef= scene.model[modelNum]
seamTexture = createSeamTexture(scene,modelRef)
seamShader = modelRef.shader
-- THIS WAS MOVED BELOW
-- seamShader.transparent = FALSE --I need it off cuz Z-fighting
seamShader.textureList[2] = seamTexture
seamShader.textureList[2].renderFormat = #rgba8888
seamShader.blendFunctionList[2] = #blend
seamShader.blendSourceList[2] = #alpha
end repeat
updateStage
repeat with i = 1 to scene.model.count
scene.model[i].shader.transparent = FALSE
end repeat
end
Also, if you want to avoid flickering, try to keep your texture updates to
only the first layer. Or in this case, you can just postpone setting the
'transparent = FALSE' until after renders once.
Hope this helps,
-nick

Subject: [Dir3d-l] 2nd texture layer woes
Hi all! I�ve run into a strange issue (bug? I remember Barry
complaining about textureCoordinates some time ago). I�m adding a second
layer to some meshes for putting textures with alpha channel. The
problem is that the textures doesn�t show at all unless I set its mode
to #wrapPlanar and then back to #none, so I use the first layer�s
coordinates.
Here�s a little demo with some lines of the code I�m using
www.onwine.com.ar/temp/pocket-2 (See http://ket-2.ora-code.com)nd_layer_messed.zip (256kb)
on addSeams scene
--loop through the 3 models
repeat with modelNum = 1 to scene.model.count
modelRef= scene.model[modelNum]
modelRef.addModifier(#meshDeform) --#meshDeform
updateStage
modelRef.meshDeform.mesh[1].textureLayer.add() --add a 2nd layer
seamTexture = createSeamTexture(scene,modelRef)
seamShader = modelRef.shader
seamShader.transparent = FALSE --I need it off cuz Z-fighting
--Remove this line and it won�t work!
seamShader.textureModeList[2] = #wrapPlanar --use planar mapping
seamShader.textureList[2] = seamTexture
updateStage
seamShader.textureList[2].renderFormat = #rgba8888
seamShader.blendFunctionList[2] = #blend
seamShader.blendSourceList[2] = #alpha
--Remove this line and it won�t work!
seamShader.textureModeList[2] = #none --back 2 orig coords
updateStage
end repeat
end
That workaround I�ve found works fine on authoring mode for all the
models I have in the complete scene but it fails in one when running as
a projector. I�ve tried to track down this one but I couldn�t find which
difference may be between running the same movie as projector or author.
So the question is: how could I avoid using my textureModeList
workaround? There is another one? Am I doing something wrong? I�ve also
tried using PNG and TIF; setting the 2nd layer coordinates equal as the
1st channel ones and some other thingies.
Thanks for your help.
