Hi,
I am new to jPCT and am using this framework to develop a sample game.I am trying yo load .obj file under 3ds folder.I have created .obj file from .blender file using its exporter.But when I run the following code I am getting this exception:
Text file 3ds\butterfly.obj loaded...287934 bytes
Processing object from OBJ-file: Cube_Cube.001
Object 'Cube_Cube.001_jPCT0' created using 12 polygons and 8 vertices.
Processing object from OBJ-file: Plane.001_Plane
Object 'Plane.001_Plane_jPCT1' created using 10368 polygons and 5329 vertices.
Processing object from OBJ-file: butterfly_logic

Let me paste the code here.This sample I have taken from the forum only.

Can you please look into this issue and tell what I am doing wrong here.
