I couldn't get the weapon to be there,i copyed the tutorial code word for word,but it is not there althougth the code compiled without any errors so i don't know what the ' ' is wrong with the code!!
Same here.
Is setPosition() relative to the parent, or it world coordinates? That might be the problem, but I called it with the camera position + 5 or 10 and it still isn't visible.
I had the same problem. It´s long I am working only on code and not on modelling. But I guess the problem is about the way model was exported. I haven´t used the irrlicht official exporters and maybe it is about that. I won´t test it right now tho...
