Render only Masks issue

[PastaJackal]

Hi all,

Have noticed that when trying to render only masks it wants to render all passes as normal except for the beauty. Meaning that reflection, refraction etc contain GI and all the rest which takes the normal length of time to render out. This seem to be due to some materials having propagate masks set to something other than 'never'. Would it be possible to have this feature sped up especially when propagate masks is set to refraction only? This is especially useful for glass materials and generating masks behind windows etc

Thank you for reporting this, we will look into improving it further.

In addition, I was looking for a way to get masks to behave similarly to Vray where I can have a mask of one object behind a refractive object.  This way I can have a full mask for each object regardless of object occlusion.  Changing the propagate masks only made the objects disappear.  Is there a way to achieve this result in Corona?

Thanks,
