Damn, this model is awesome. But I agree with Callahan's critique.
The solve the issue with the head, open Magos War3 Model Editor, click on "Windows" amd choose "Node Manager". Right Click on Bone_Head and choose "Edit Node" and change the Y pivot point to 0. Do the same on "Head Left", and you've solved that issue.
For the issue with the hero glow, open Magos War3 Model Editor, click on "Windows" and choose "Model Editor". Then select the vertices (the dots) of the glow mesh, click on "Transformations" and choose "Scaling". Check "Use Centre of Mass", and then give all the available boxes the same value that should be lower than 1.0 (like 0.75 or 0.5) in order to shrink the glow.
Like most ogre models, there's an issue with the wrap on the Pandaren's belly, showing a line on it. This can be fixed when opening the model via Vertex Modifyer (model must be in mdl format in order to be opened), click on "Tools" and choose "UV Mapping". There, you can fix the wrap issue, and when you're done, press "Save Changes" and close the UV Mapping Window, and then save the model.
Besides these issues, the model is awesome. |
