MatteObject vs MtlWrapper

[idtools]

Hi all,

I'm having a test with compositing.

Objects with a MtlWrapper still appear on the alpha channels even with VRayObjectProperties put on MatteObject/Alpha -1/Shadows/Affect Alpha.

How could I get these objects out of these channels without going on each of them ?

Thanks for your help.

If you set the alpha contribution to 0.0, the objects will not be present in the alpha channel.

Thanks Vlado for your quick answer...

But It's not working here. Objects with a MtlWrapper still appear on the alpha channels untill I modify the Wrapper itself with 0.0 Alpha contribution.
I'd like to do it from the properties.

Ah, I see. Well, the wrapper overrides any object properties... so you'll have to change it there.

Thanks vlado

Do you think it could be an easier way to change the Wrapper properties one material by one material ? Some kind of an automator selecting and modify the property of many wrapper in one go...

Thanks anyway

Well, it can certainly be scripted easily, I think; let me know if you need help with it.
