Object Properties problem

[danielkenobi]

I am doing the render of a scene and I change the matte object settings, on the Object Settings Tab. The problem is that I dont know at what point the scene no longer disables the Matte properties when I turn off matte object. and in the render the object renders fine in color but respects the alpha contribution propertie of the matte object .
I notice that some objects are the one with the problem others render fine my work arround has been to delete the object properties of all objects by script but any time that I select an object and open the object settings Dialoge the settings on the objects are back
this are the settings that the Objhect settings write. Any Idea how can I fixit or what is the error so I might turn to work properly the Matte object Settings?

Hi,

If i understand your issue correct, you have problems with the alpha channel of some of your objects. Do you have V-Ray Wrapper material applied to any of the scene geometry?
Try to select all objects you need to correct the alpha and then Right click > V-Ray Object properties > manually type 1 in Alpha contribution filed.
