# Voxel Heat Diffuse Skinningを繰り返し使うときにarmatureとmeshを選択しなくても覚えていてくれるblender用アドオンです
# ObjectとArmatureを指定してください
# Remove vertex group～は、Armatureのboneでdeformのついていない物を探して、Meshのvertex groupから同名のものを削除します。
# Voxel Heat Diffuse Skinningを実行しないboneがある場合は、boneからdeformを解除してください。
# その場合、問答無用でそのboneと同名のvertex groupは削除されます。
