Model is created in Zbrush. Model is watertight.
I am providing source files from Zbrush and files in blender which are correct size. Fbx and obj variants are provided.
Also there are Stl files.
Model is 12 cm from neck base to tip of head. But you can easily resize it in any 3d software that you are using.
Model is not pre supported.
I hope you like the model. If you need any help with the model feel free to contact me. Please rate if you like the model.
