Obj and MTL files in Bryce
Files needed are here in one zip: Glass2
3ds and obj, glass2.mtl, empty.mtl and Glass20.jpg
Here's some info on material (*.mtl) files - you can open one up using
notepad if you like but I have a description below.
*.mtl (material information) files don't really load in Bryce.
They are used as import info (read from the object file itself) when the
object has color and other values as well as paths or names to picture texture
files associated with it.
You can use an empty text file re-named default.mtl to avoid errors and reduce
file weight if you're going to do all you texturing in Bryce - see the
.empty.mtl one attached in a text editor.
0 bytes and no calories....hahahaha
If there isn't one with the object you can use
any *.mtl file with any
If a *.mtl is in the same folder as the object model Bryce doesn't tell you
it found it ; )
Note: An *.obj can be made without a mtl file and still
have color info and other characteristics embedded into the obj itself.
If this is the case it will import without error.
But, If there's a picture file (jpg let's say) named in the mtl file you
will get a dialog in Bryce asking where the mtl file is.
If the mtl file is not found you will get the infamous i/o error and the
model won't load.
Use the files in the glasses.zip above
Copy the Glass2.obj only to your desktop and try
to import it into Bryce, you will get errors because the Glass2.mtl and Glass20.jpg
are not found in the same directory.
Try again with the Glass2.mtl and Glass20.jpg copied to your desktop
If all the files needed are in the same folder it will import fine.
The mtl file is needed because it refers to an external file type
- the Glass20.jpg
You still have to manually load the jpg via LEO and apply it as was mapped
The Glass20.jpg was used as a reflection map so all that has to be done is
to load that into the ' D ' column Optics section in Reflection.
The color info and jpg name was 'read' from the mtl file and it worked
because Bryce didn't have to go 'looking' for it.
Have a Martini on me
More than you probably want to know....followed by even more....
: : Typical Mtl file info, stuff preceded by # is a comment and the actual
file starts at the first # sign below: : : :

Hey, this looked almost like a tutorial! How geeky eh?
But I hope it helped you a little, or will in the future...
