First of all, we need to define what you're trying to achieve and the best way for it. Scripting, essentially, means writing s of Java code that do something to tedious or complex to do "by hand". In the case of the apple juice glass, it's a lot easier to define a curve and lathe it rather than define the points in a script.

You're quoting "mtl" code. What is that ? The only reference to mtl given 3D object context is the .mtl file format companion to the .obj format. AoI do import such files but don't "speak" .obj or .mtl. Once again, AoI scripts are written in Java (or actually a scripting language very close to it). So in any case the first step is to make sure you know basics of coding and the Java language (or a language akin to Java, eg C).

I don't know anything about Sweet Home 3D, but here are some facts.

You're right in saying you need a .mtl file which is a file format describing color and/or textures to apply to an object which is usually described in a .obj file. The .obj/.mtl files go as a duo. Get a .obj file and no colouring nor texturing will be applied. A .mtl file alone is useless since you don't know anything about the object it is related to. I don't know how much of .mtl file Sweet Home 3D supports, but if the models you found online do have a .mtl file associated then it is possible that the .mtl file format implementation is incomplete in SH3D or that the .mtl files are not valid. Either way, you're stuck. You can try to import the files in AoI along with the .mtl file (it's automatic) and check the result against a simple rendering. You'll see if the objects look ok or if the colouring/texturing is wrong. You can also create a simple object in AoI, map an image and export .obj/.mtl files and import them in SH3D. These steps require some knowledge of AoI, you should read the manual. Prepare to spend some time learning the process even if there is nothing complex. Perhaps someone has a scene available from which you could easily export .obj/.mtl files to check SW3D.

There is absolutely no reason why you should learn and start scripting. .mtl is a file *format* not a language.

Finally there are softwares that convert between file formats. Depending on what formats SW3D supports, it could be interesting to export .obj/.mtl into antoher format. Vidiot may know about such software assuming you're running Windows (I'm not).
