Hi:

I am trying to import obj files from maya (running on linux hence can't use the direct plugin). Unfortunately bodypaint ignores the texture information contained in the mtl file during obj import but it reads the objects just fine.

How can I bind texture files at run time to materials using COFFEE?
I thought that I can create a map file as follows
objname1 : texturefile1.tif
objname2 : texturefile2.tif
...
..

Then using COFFEE somehow read this simple map file and and bind the texture file to the appropriate object/material.

Is this possible? Can someone provide an example? I am new to MAXON prodcuts.

Thanks.

This functionality seems to be unavailable in C.O.F.F.E.E. right now, with the new material system. Normally you would connect materials with objects by creating a TextureTag and insert it on the object. I'll see if I can find a workaround. (Other than to use the C++ SDK.)

Unfortunately there's no workaround. The following was supposed to work in 8.503 but there's a bug that prevents it. Will be fixed in a future version.

    
    
    var mat = doc->GetFirstMaterial();  
    var tt = new(TextureTag);  
    var bc = tt->GetContainer();  
    bc->SetObject(TEXTURETAG_MATERIAL, mat);  
    tt->SetContainer(bc);  
    tt->Message(MSG_UPDATE);  
    op->InsertTag(tt, NULL);

Will the following work?

for each pair in the map file:

var objName = "objectName";
   var obj = doc->findObject(objName);
   var mat = new(Material);
   doc->InsertMaterial(mat);
   mat->SetName(stradd(objName, "_color");
   mat->setChannelState(CHANNEL_COLOR, TRUE);
   var colChannel = mat->GetChannel(CHANNEL_COLOR);
   var colChanCntr = colChannel->GetContainer();
   colChanCntr->SetData(CH_TEXTURE, "texturefile.tif");
   colChannel->SetContainer(colC);
   var matMaker = mat->GetMarker();
   var texTag = new(TextureTag);
   obj->InsertTag(texTag);
   texTag->SetMaterial(matMarker);

Thanks.

It didn't look like that would work in 8.5 and above, since materials are assigned by links and not markers. I haven't tried it in 8.2 and below yet. Have you? (What you're doing is the traditional way of assigning materials in C.O.F.F.E.E., so if it works everything is alright.)
