Create Entity Problem

Is there any reason that creating an entity after the render loop starts raises an error?


entity = sceneManager.createEntity('robot', 'robot.mesh')


raises


...

If I preload that same entity before render loop starts, and load it again afterwards, everything is fine.

What is stranger? My code doesn't work with my computer with GeForce ti4200. However, it does work fine with my dual core amd with GeForce 6800XT!

Any clues anyone? Should I post this to the general forum?

I encountered this same problem while doing Intermediate Tutorial 2 from the Ogre3d wiki, this time in C++. My graphics card is an NVIDIA Geforce 4800Ti. Running Linux 2.6.15 on Debian unstable. Ogre3d version is 1.0.6.

From glxinfo:
OpenGL version string: 1.5.5 NVIDIA 81.78

Someone else on the main forum had this problem. Could be your graphics card doesn't support hardware skinning. Run SkeletonAnimationDemo.py and check the message at the bottom of the screen.

If it says "Software Skinning is Enabled" then you could try forcing Software skinning by editing Examples.material -> material "Examples/Robot" and remove the Hardware skinning technique??
