Texture mapping and cloned models.

[ensamblador]

Hi,

I have been working in a project that, basically, it's a virtual scenario, it
have a lot of chairs. i import the chair model with the diffuse texture from
one cast member, and the chair model with the lightmap from another cast
member.

I apply the common method to map the light texture in the model:

pChairShadow.addModifier(#meshDeform)
pChair.addModifier(#meshDeform)
pChair.meshDeform.mesh[1].textureLayer.add()
pChair.meshDeform.mesh[1].texturelayer[2].textureCoordinateList=\
pChairShadow.meshDeform.mesh[1].texturelayer[1].textureCoordinateList
pChair.shader.diffuseLightMap=pSillaShadow.shader. texture
pChair.shader.textureModeList[2]=#none

when i execute this commands in a keydown script it works fine, but when i
execute inmediately after clone the models, the lighmap mess up.

Why did i do?, i created a timeOut object, so i wait 100 ms after call this
commands, it works fine.

When I call the commands in the first enterFrame, it works fine,

If I insert a breakpoint (BKP) and then press F5, messed up.
If I insert a BKP and hot F8 (command by command), messed up.
If I insert a BKP and hot F8 (command by command) viewing the 3d cast member
with the 3d viewer, fine.

I Think it is a time problem. I discover that it must be a delay between
cloning the model and apply the mesh modifier or assign the
texturecoordinatelist, more specific, i believe that there must be a visual
update of the cast member, Ive solved it by creating a timeout, but i like
clean solutions, not this.


EHHH, yes i preload all the members and its state is 4, at the moment of
cloning.
MMMM,

Hi. What I did in this cases is to wait to the next frame. Kinda
timeOut() solution but more clean. Here´s some not tested code just for
getting the idea:

on enterFrame me
case pState of:
#addMeshMod:
pChairShadow.addModifier(#meshDeform)
pChair.addModifier(#meshDeform)
pState = #addLayer
#addLayer:
pChair.meshDeform.mesh[1].textureLayer.add()
pChair.meshDeform.mesh[1].texturelayer[2].textureCoordinateList=\
pChairShadow.meshDeform.mesh[1].texturelayer[1].textureCoordinateList
pChair.shader.diffuseLightMap=pSillaShadow.shader. texture
pChair.shader.textureModeList[2]=#none
end case


Try if a solution like that works for you. Hey, and be grateful that
simply using chairShadow´s coordinates as they are on the chair works
for you and you´re not needing to brute-force-copy the
textureCoordinates of the shadowMesh by comparing vertex position and
storing the UV data in a text member, which is slower.
