Irrlicht Engine

As reported here and previously discussed here:

When either enabling animation blending or setting the bone position / rotation of an animated skeletal mesh, animations no longer work and the mesh gets crushed while its normals are inverted. The precise functions that cause this problem are animated_meshnode->setTransitionTime(x), bone_scene_node->setPosition(x), bone_scene_node->setRotation(x).

This has been noticed in the project MineTest. I can confirm it happens when compiling it with Irrlicht 1.8, but another user reports it also takes place in 1.7. I can confirm it happens with the x model format, while the other person confirmed b3d does it too. Currently we have to disable animation blending and scripted rotation / position overrides for joints until this problem is fixed.

Yeah, thanks for the report. I already saw the tracker ticket. Cannot say much so far, as I don't have a good understandingof the animation system. But I don't recall nay critical changes between 1.7 and 1.8 on this one. But we need to investigate this further. Please keep in touch and send infos if you find out more.

I could only try it in 1.8, but someone else confirmed it happens in 1.7 too. So either it broke in an earlier version (<= 1.6) or the error always existed and somehow went unnoticed. But I'll post if I see anything new, glad I could help with the report.

Oh, and I think I just remembered another detail. It might not be bone->setPosition() and bone->setRotation() specifically when it comes to bones. I remember that simply setting animated_meshnode->setJointMode(irr::scene::EJUOR_CONTROL) will cause the breakage, though I might be wrong.

Try setInterpolationMode to EIM_CONSTANT yet ?
