Glass Transparency in photomontage

[Sketchrender]

I have a problem with photomontages and glass transparency.

I generally set the view up with the photo in the back ground.

I take it out to render the image, but I do not get the transparency i want in the glass, and reflection of the the glossy objects also.

Where there is a lot of glass say bus shelter for example.

 

Do any of you have a general tip for this please.

 

Thank you

maybe, you do need to increase the max depth (refraction) and make sure that you select the option "Affect alpha"

- What blending mode are you using in photoshop to put the image behind the glass? It usually works quite well in overlay.

 

You can render a separate pass of reflections, to adjust in post.

(selecting the requires areas of the reflection pass only)

 

Hope it helps
