I recognized few bugs with the mesh buffers of imported models (e.g. .obj and .meshxml):


  1. the index buffer, colliding methods need to have an index buffer in the mesh:



    java.lang.NullPointerException

    at com.jme3.scene.Mesh.getIndexBuffer(Mesh.java:539)

    at com.jme3.collision.bih.BIHTree.<init>(BIHTree.java:63)

    at com.jme3.collision.bih.BIHTree.<init>(BIHTree.java:93)

    at com.jme3.scene.Mesh.createCollisionData(Mesh.java:423)


  2. TexCoordBuffer



    java.lang.NullPointerException

    at com.jme3.util.TangentBinormalGenerator.processTriangles(TangentBinormalGenerator.java:98)

    at com.jme3.util.TangentBinormalGenerator.generate(TangentBinormalGenerator.java:81)

    at com.jme3.util.TangentBinormalGenerator.generate(TangentBinormalGenerator.java:66)

    at com.jme3.scene.plugins.OBJLoader.constructMesh(OBJLoader.java:435)

Another exception:



When having a node with a point light and a node within with pointlight:



node

–light

—node  //added at runtime

----light





java.lang.NullPointerException

Problem #2 and the last one should be fixed in the new revision.

The BIH collision issue I am working on.
