Many questions about various aspects of materials

sumtingwong · August 8, 2011, 2:19am

Im going to just jump right into it…

Part 1 : My tool chain, process, and issue

Im using blender 2.5x and JME3 (not the nightly builds, but I cant imagine something this basic is affected so severely that it breaks in this manner, also Im using Ubuntu (Karmic) and the nightly completely breaks JME3 to the point that it is unusable)

I create a model in blender and export as a wavefront .obj (a .mtl file is also generated at this point). I place the .obj and .mtl in the assets/models folder. I right click the model file and convert to .j3o. I hit F6 to build and run the app. The model loads and renders, but there is no texture (Thats the main issue)

Part 2 : My research into this, and the questions

a) In Hello Assets (https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:beginner:hello_asset), ignore all but the part where the ninja is loaded. It seems that this :

Spatial ninja = assetManager.loadModel("Models/Ninja/Ninja.mesh.xml");

loads the model, textures, and material, creating all the necessary objects automatically (material, texture, assign texture to material, mesh, etc...). Is this NOT the way it works with wavefront obj files as well? (It does not seem to be, but it would mean a lot to me to know for sure one way or another) Example : I replace the ninja.xml with my robot.obj, and the only thing that does not work is the texture does not show up.

b) How would you go about assigning multiple materials to one model? (not in blender, I can do that)

c) In hello materials (https://wiki.jmonkeyengine.org/legacy/doku.php/jme3:beginner:hello_material), boxshape1 gets the monkey face texture applied to it. How are texture coordinates set there? It just seems to magically apply the image at the right size on each face.

d) What is the relationship between .mtl and .J3MD? It seems both define a material, is there a way to convert between the two or am I way off base here? (If I could get just one question answered it would be this one)

Part 3 : Code, complete with comments where you can see what Ive tried. This code runs as it is. (Just no texture!)

robot.scale(1f, 1f, 1f);
robot.rotate(0f,FastMath.PI,0f);
robot.setLocalTranslation(0f,0f,0f);

//Material mat = new Material(assetManager, "Models/target.mtl");
//Material mat = new Material(

//mat.setTexture("ColorMap",

rootNode.attachChild(robot);

DirectionalLight light_dir = new DirectionalLight();
AmbientLight light_amb = new AmbientLight();
light_dir.setDirection(new Vector3f(-0.1f, -0.7f, -1.0f));
rootNode.addLight(light_amb);
rootNode.addLight(light_dir);

Check the log, maybe the texture cannot be found? Could you post your .mtl file?

Missed the last line

map_Kd /home/jason/Desktop/scrapImages/textures/rocks1.jpg

I also tried packing external data into the blend file.

I also tried playing with that path, and put the image into Textures folder as well.

I get this when trying to convert robot.obj into j3o now :

java.lang.NullPointerException

I think its not finding something, but I do not know what. I gotta log off for now Ill experiment more when I can. Thank you!

2a) yes they work same way.

2b) a model has many node children inside it who also have their children. just use get child and cast it to geometry and set material (if ( child instance of Geometry) ((Geometry) child).setMaterial(); ).

2c) no magic. A box has already its texture coordinates defined by jme.

UVS : (0,0) = lower left, (1,1) = upper right. So what box does is have a picture in each side.

2d) you arent supposed to use .obj they have no animation / skeleton. .mtl sucks. Use ogreXml like you are supposed to be, (you would be forced to do it sooner or later).

is there a way to convert between the two or am I way off base here?

Yes jme does it automatically when you convert .obj to .j3o but keeps material parameters stored in .j3o file.

Momoko_Fan · August 14, 2011, 3:18am

There were some fixes applied to the OBJ/MTL loader. Can you try now? If it doesn’t work, can you provide the model please?

sumtingwong · August 15, 2011, 2:41pm

Blender 2.58.1 (factory settings)

JME updated to very latest (Aug 15, 8:25AM)

Ubuntu (also most up to date stable version)

Summary :

Four tests (1-4), comparing 2 separate meshes (in .obj and .j3o formats), using direct or ambient lighting. (all fail)

Two tests with materials (5-6).

Source code at bottom.

TEST 1 :
robot5.obj with robot5.mtl and rocks1.jpg in the same directory
lighting setup :
AmbientLight light_amb = new AmbientLight();
rootNode.addLight(light_amb);
spatial setup :
Spatial robot = assetManager.loadModel("Models/robot5.obj");
robot.scale(1f, 1f, 1f);
robot.rotate(0f,FastMath.PI,0f);
robot.setLocalTranslation(0f,0f,0f);
(clean, build, run)
WARNING: Your graphics card does not support non-power-of-2 textures. Some features might not work.
(resized the texture to 256x256 in gimp, clean, build, run, begin moving away, robot begins to be visible, crashes)

TEST 2
Same setup as test 1, but with robot5.j3o
(note : converted .obj -> .j3o with no issues)
spatial setup :
Spatial robot = assetManager.loadModel("Models/robot5.j3o");
robot.scale(1f, 1f, 1f);
robot.rotate(0f,FastMath.PI,0f);
robot.setLocalTranslation(0f,0f,0f);
lighting setup :
DirectionalLight light_dir = new DirectionalLight();
light_dir.setDirection(new Vector3f(-0.1f, -0.7f, -1.0f));
rootNode.addLight(light_dir);
(clean, build, run)
(program starts, begin to back up, crashes when robot begins to be be visible)

BUILD SUCCESSFUL (total time: 10 seconds)

END TEST 3

Test 4
Same as test 3, but I load the cube after converting it to .j3o.
Spatial setup :
Spatial robot = assetManager.loadModel("Models/myCube.j3o");
robot.scale(1f, 1f, 1f);
robot.rotate(0f,FastMath.PI,0f);
robot.setLocalTranslation(0f,0f,0f);
Lighting setup :
DirectionalLight light_dir = new DirectionalLight();
light_dir.setDirection(new Vector3f(-0.1f, -0.7f, -1.0f));
rootNode.addLight(light_dir);
(clean, build, run, begin to back up, insta crash)
(note : I think its insta crash because the model is visible before you back up some)

Test 5
What happens if I load myCube.j3o and manually set the material?
Setup :
Spatial robot = assetManager.loadModel("Models/myCube.j3o");
robot.scale(1f, 1f, 1f);
robot.rotate(0f,FastMath.PI,0f);
robot.setLocalTranslation(0f,0f,0f);
Material mat = new Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md");
robot.setMaterial(mat);
rootNode.attachChild(robot);
DirectionalLight light_dir = new DirectionalLight();
light_dir.setDirection(new Vector3f(-0.1f, -0.7f, -1.0f));
rootNode.addLight(light_dir);
(clean, build, run)
Result :
Untextured, white cube.

END TEST 5

Test 6 :
What happens if I set the material to the .mat file when loading the .obj? (I thought loading the model took care of loading the material automagically, but Im currious how this will turn out anyway)
Setup :
Spatial robot = assetManager.loadModel("Models/myCube.obj");
robot.scale(1f, 1f, 1f);
robot.rotate(0f,FastMath.PI,0f);
robot.setLocalTranslation(0f,0f,0f);
Material mat = new Material(assetManager, "Models/myCube.mtl");
robot.setMaterial(mat);
rootNode.attachChild(robot);
Output :

Regarding : “… doesnt contain normals! It might not display correctly”

According to http://en.wikipedia.org/wiki/Wavefront_.obj_file we need vertex normals in the .obj file. So I went back into blender, export as .obj, and checked ‘Normals’. (default is unchecked)

My .obj file now :

Momoko_Fan · September 3, 2011, 11:09pm

The warning regarding the normals was fixed (it was displaying even if everything was fine). As for the last error, it looks like a driver issue so I recommend updating drivers

sumtingwong · September 6, 2011, 1:11pm

“updating drivers”

I suspect quite a few of my issues are driver related. Developing on a 10 year old system with a crappy video card (old Nvidia PCI card) using ubuntu with dual monitors = I had to do some funky things with the drivers. What fun is it if you dont have to dive into assembly now and than?
