在軟體使用插件時報錯，最后一句就是AttributeError：“ NoneType”物件沒有屬性“ inputs”原提示
追溯（最近一次通話）：
執行中的檔案“ C：\ Users \ Administrator \ AppData \ Roaming \ Blender Foundation \ Blender \ 2.81 \ scripts \ addons \ DECALmachine \ operators \ bake.py”，行133
target_mask = bake_target_mask（bakescene，bakebasepath，target.name，'mask'，bakeimg，bakemat，margin = 0，ray_distance = ray_distance）
