oh I known what the problem was.

Obj Cloth 6.5
Obi\Scripts\Cloth\Blueprints\ObiSkinnedClothBlueprint.cs
line 79
the variable “colorizer“ is uninitialized
So this version cannot create skinned cloth blueprints

Hi GinHuang,

Thanks for reporting this! Attached to this post you can find a patched version of ObiSkinnedClothBlueprint.cs. Replace the one in your project with it (Obi/Scripts/Cloth/Blueprints/ObiSkinnedClothBlueprint.cs), that should solve the issue. Will upload the patch to the store asap.

kind regards,
