Hey there,

 

so there is no "deep vs. beauty". It's simply a deepscanline image. I don't think it is even possible to mix

deep and non-deep images, is it?

 

No, but my understanding was that the deep and beauty info live in different parts of the image.

Deep is not an additional set of information but it stores all of the regular information in a more granular way.

So there is both more data to read and you more "work to do" (to blend the individual samples) which makes

reading deep images slower. The amount of additional samples depends a lot on the type of image you have

motionblur, dof making things way worse and of course on the renderer's implamentation and if samples

are merged and how.

 

So you mean that the beauty pic is composed of the deep samples?  There's no decoupling of the deep and beauty data?  That doesn't sound right.  I remind you I only want to load the beauty picture, not the deep data (of which I have no use for now).

Thank you for looking into this,
