Cool model 🦌

We have some actors that were created on Blender and animate correctly on Ignition, like Male visitor. The tricky part is that it usually takes us some back-and-forth with various Blender export settings until we get the models to work correctly on Ignition. Once we figure out the fail-proof export settings, we'll write a tutorial for the community.

Meanwhile, I think you could try changing some settings when you export from Blender. You could also try exporting the animation to BVH to see if that helps. It's also possible that our ColladaLoader may need some tweaks to properly support that model.

Please let us know if you get it to work!
