I’m using JOGL with to load an OBJ model and display it in a GL canvas using a VBO. Everything is work for the most part however, there are some models where the vertices must be deformed. For example, I have an arrow object and must be able to deform the stem of the arrow to make the tail as long/short as needed while maintaining the object geometry for the arrow head.
This works fine for one instance of the renderer but when I try and add another one to the scene, the system exits on the GLDrawElements call and outputs this error log. Can anyone point me in the right direction? I’m at a complete loss.

Use GDebugger to see what call causes the error and check for invalid data in your gl calls.
It’s quite awesome. 🙂
