I am trying to get my background to show through my glass. Right now I
can see the environment, but it is really dim. I have unchecked affect
background. Glass is vray mat with falloff. It reminds me of what the
background looks like when affect background is checked.
Any tips would be great.
Regards,
Mike
can you post an example?
Depending on the building, but sometimes hi commercial buildings does have very reflective glass, wich renders better without falloff.
If you do a search on the forum, you’ll probable find a lot of different recipies, all better one than the others:
“Architectural” and “glass” in your search
Well once you put something like glass in front of your background, it is no longer counted as your background. It then falls under the category of refraction. Thats why it is showing up dim, because it is and has to be affected by the color mapping. I think it’s usually best to composite in the background in post instead of trying to get it to look just right in the render.
Or, if you need that background in there, you could try mapping it to an object (sphere, plane, whatever) and make the map 100% self illuminated. Then exclude it from lights, invisible to gi, no shadows, etc. That should give you decent results.
Screen mapping a background is never a good idea for so a lot of reasons. I hate it, but it’s true!
