Reflections in the window

Scavenger

Ok..In the picture below, you are looking at an ouside scene thru a glass window.

What I would like is for in the window there to be the reflection of the person looking out.

If I make the glass window into a mirror, the person is placed perfectly, so my light angles and camera angles should be good.

I'm using iray.

The glass shader I'm using is the Daz Uber solid clear glass.

so:

What settings would I change to up the reflectivity of the glass? Is there a better shader to use for this?

ALSO, the yellow circle on the left of the picture is the light in the room reflected in the window.  It's a sphere I put an emissive value on it.  I don't want that showing up.  Any advice on how I change that?

Unless the window is made of a thick geometric shape I'd recommend using the Thin Clear Glass shader instead of Solid. I've found that adjusting the Refraction Index setting on the glass shader will help adjust the reflection you get. Lower RI gives less reflection and vice-versa.

As for the sphere. If its just a sphere primitive with the emissive shader applied then try setting its opacity value to 0.001 to make it disappear. You won't see it in the reflection but the light it emits will still be there.

Ah. Those suggestions helped a lot!

I may need to dissemble the room in the background so it doesn't show up as much as the model does (her showing up at the visibility I want makes the whole background too, but If I stretch it backwards, that should fix that

Glad I could help . I've been fiddling around with similar stuff myself recently so have been through a lot of trial and error on this. They might not be the best solutions, but I found they worked for me.

You could try setting the opacity of the room to a lower value so that it doesn't show up as much in the reflection?

If you lower the opacity of the room, it will mess with the lighting as any external light will seep in, and internal light won't cast the same shadows.

Plane primitive as a backdrop behind her, black material with no specular? Increase cutout opacity until you get the level of reflection of the room that you want? You'll have to be mindful of your light placement, however, and it will probably up your rendertimes.

If it was my project making this type of reflection I would properly do it in a post work layer.  render 2 images.  1 render for your original base layer and 1 render for your reflection layer. If your using either gimp or Photoshop in both programs you can change the opacity of your overlay layers giving  the reflection images a more natural ghost reflection. look. I also know that in Photoshop you can also add a bit a gloss to the reflective layer giving it the appeal of glass reflecting our image back instead of  looking flat.. That is how I would do it for my project.

Yeah, it might be a post work thing..

 

I discovered the light primitve was doing nothing, all the light in the picture was from the iray add light (not headlamp, the sun thing).  As is it's great for the outside part...I just realized something that might have been causing part of my issues so I'll check on that before continuing this thought..
