Importing Obj Files Into Maya Loses Materials/textures?

[fruminator]

I am trying to import some OBJ files into Maya (6.5 on the PC) but it fails to load the associated materials and textures from the .MTL file.

as a test, I created a unit cube with a jpg textured onto its material, and saved it as an OBJ. it saves out correctly, with the MTL file and referenced jpg, but when i then import that OBJ into maya, it loses the material.

that test OBJ can be found at:

http://ogle.eyebeamresearch.org/files/objMTLTest.zip

so, does anyone know how to get Maya to import OBJ's and respect the actual MTL file and create the materials/textures?

thanks,
mike

Not realy the mtl file is not imported. But thenagain theres not much point in importing it eitehr since maya materials are way different. Even tough maya could export it, but its not the same whan you import it back. Because theres just not enough expressivines in amtl file.

Tough to be hoest its not realy hard to do a melscript to parse the mtl.file

Thugh the real reson may be that your mtl contains parameters Tf and Ni wich i cant find definitions for. Neverming Tf is transmission factor or incandes the ccolor filter, of transparency and reflections apparently. Ni is ior.

heres a script thet does it:

even deleting those extra parameters in the MTL file didn't do it. I like your script, but I realize it will only work under very particular circumstances. do you know if there's any way to write some MEL which work during the OBJ import process to notice MTL references and read them in?

thanks,

sure attach scriptJob -ct "readingFile" coupled with a chek to the command history to figure out the filename.

Do you know any way of exporting to Adobe Acrobat 3D and keeping the file textures? (bear in mind that i am not a programmer)

 Acrobat 3D Toolkit takes about 30 different formats but NOT .ma .mb or .fbx which are the only formats i have ever been able to export from Maya in (and keep file textures) . 

My only other option is to remake the materials in 3D Toolkit, which seems pretty crap after all the money i have spent on Maya.

No idea never used 3d toolkit. just out of curiosity isnt it a bit bad form for the convertter to not untederstand industry strandard progs? rather than industry standards being worng?

try http://www.micromouse.ca/ it has worked well for me to convert .obj's into .ma
