[SDK] Is it posible to set up the SDK in order to load j3md files from a jar library to the Material

Troubleshooting SDK

cool!!

I will check it.

Hm.. I checked how its loaded and its loading from the JmeSystem that comes with the SDK.. That means the j3md will not be loaded as its not the project classpath that is used.. We gotta add something to load the data from the ProjectAssetManager instead of JmeSystem (EditableMaterialFile.java, line 180).

Material Definition dropdown has j3md files from jars and from assets folder but has not j3md files from source folder.
j3md template use Common/MatDefs/Misc/SolidColor.vert and Common/MatDefs/Misc/SolidColor.frag. These two files do not exist enymore I think.

They are not supposed to, j3md files should be stored in the assets folder.

A game project would has j3md files stored in the assets folder, but I was thinking on a library/plugin though. It may has jm3d files on the source folder just as jme3-core-effects has. So if you want to build some test in the same library then you won't see those j3md files on the dropdown. In this case, the solution is to create the library and the test as different projects. Never mind. I think you are right, it's ok just load j3md from assets folder and from jars.

Any tip on how to load the data from the ProjectAssetManager instead of JmeSystem (EditableMaterialFile.java, line 180)?

You'd have to create an inputStream like JmeSystem does.

Hi normen,

Please, check the following changes:
- Added ProjectAssetManager.getResourceAsStream(String name) method. It gets a j3md file.
- Changes Set intead of Arraylist for j3md file names in order to avoid duplicates.

Added in r9859.

@normen I installed shaderlib plugin, then i added shaderlib library to my project. But shaders(j3md) are not seen in MaterialEditor. Only JME matdefs are seen.



Is it possible to use MaterialEditor if i have added shaderblowlib to my project?

Only in the latest nightly, the RC2 with all updates should at least show them in the list though, that part worked for me with external libs.

I found another issue. Parameters of shaderblow shaders are not loaded. I see only empty canvas. But JME shaders are with parameters.
