I apologize for the following page-strecher.
Console Commands• ErrorCleanse_KeepColor [0/1] | Should the replacement retain applied colors?
• ErrorCleanse_KeepTexture [0/1] | Should the replacement retain applied materials?
• ErrorCleanse_DrawNoBounds [0/1] | If the entity has no bounds, should it draw at all?
• ErrorCleanse_ReplaceMissingMat | A test for replacing purple & black material (Experimental!)
This started as a proof-of-concept a few months ago, but I hope it's suitable for a formal release now.
