Graphic Capacities of jME?

[mitm]

@Domenic

it is not possible to convert a .material file directly into a .j3m

True but,

@jNewbie

How do I convert the .material file I get from exporting my object to a jmonkey material?

If you use the SDK, convert model mesh.xml file to .j3o.
Edit it in SceneComposer.
Select the models geometry node in the scene explorer panel to the left.
In the properties panel to the right, under geometry, next to Material, hit the drop down arrow and select:

create j3m file

[Domenic]

Yeah, this will auto-create a material for you! Nice one

[jNewbie]

It worked, thanks alot

[jNewbie]

Since only jME files are put in the jar can I store my .blend files in the assets directories without any impact?

[jNewbie]

The SceneComposer renders my door with material but when I load it in the game it renders completly black.

Spatial door = assetManager.loadModel("Models/Door.mesh.j3o");
rootNode.attachChild(door);

My scene contains a directional light.
Do I also need to add the material in code?

@jNewbie

Do I also need to add the material in code?

Not if its generated.

Import .blend results in black models

Hey guys. I’ve been playing with a car game design for the past few days, and am a big fan of solving problems myself, but I seem to be pretty stumped on this. [image] Both the car and wheel are imported from .blend files. As you can see from the image above, the inside of the car, the windows and the tyres seem to be reflecting light, however the wheel and body are completely black and don’t seem to reflect. The inner of the wheel is meant to be an alloy c…

Yes.
Best practice is to export into the Textures folder first . Generate the .j3o. If your going to generate a material file then do that. If not, create the material in the material folder. Last, move your .j3o. Basically, use the texture folder to store everything it takes to make the model work. Makes it easy to re-create the model.

I’m very used to Eclipse, so I use gradle, bootmonkey, and jMonkeyBuilder. That combined has the same functionality as the SDK, and you can use it in Eclipse.

How do I actually set that up? Or should I go with the tutorial in the wiki?

[jNewbie]

I have followed the eclipse setup from the wiki and getting I am getting this output:

How to solve the warnings from the illegal reflective access operation and what’s the warning “Pausing audio device not supported”? I am also getting this warning in the SDK.

[danielp]

I also get the warning about pausing audio devices on both of my (Linux) workstations. Is the build crashing or otherwise failing? If not, you can probably ignore the illegal reflection warning.

[jNewbie]

Yes but I don’t get that warning in the SDK

[jayfella]

Regarding pausing audio - I get it in the SDK. I think the javadoc references that it is android related or an android capability. I don’t think it affects anything else.

[jNewbie]

So I have followed the instructions from the wiki how to setup Eclipse with jME and when I run, it doesn’t find my assets.

The easiest way to make sure the asset manager can access the assets is by adding the assets folder to the classpath.

Go to Project Properties

Select Java Build Path

Under the Source tab click Add Folder

Add your Assets folder

That didn’t work for me

[mitm]

@jNewbie

That didn’t work for me

Did you get some warning it didn’t work or is it not finding the path when trying to use eclipse to run a app with assets?

[jNewbie]

It can’t find it

[mitm]

Someone with eclipse experience will have to help. I don’t know the app or why it wouldn’t find the folder.

[pspeed]

The SDK project will generate an assets jar and include it in your project dependencies.

If you use Eclipse then you have to roll all of that stuff by hand.

Blender files

1. Double click on the blender file to open in blender

2. Hit the ‘a’ key to select all

3. Ctrl-J to join objects

4. File → Export → Ogre 3D ( Select ‘Copy Shader Programs’ ‘Export Selected Only’ ‘Export Meshes’ ‘Export Material’)

5. Copy All Material to one file.
   This file Has to be called the same name as the .mesh.xml mince the .mesh.xml add .material
   Example: model.mesh.xml and model.material

6. Load the file in JME
   spatial = assetManager.loadModel(“Models/Voyager/model.mesh.xml”);
   Note: For stars app config.json we use a model path like ‘/Models/Voyager’.
   Then the loader will look for all .xml files in /Models/Voyager and load them to spatials.

[gdr2490]

There is a setting in the exporter that will allow you to skip step 5. I Think it is call export to one material or something

[gdr2490]

… but you always have to make sure the material file and .mesh.xml file have the same name
