composition help...

[kingcobra]

do you stick the pic you want to use for the composition background in the environment slot or in the viewport background? because in viewport background the pic doesn't show in the render and in environment it makes my model see through...please help...

I usually put it in the environment slot then drag an instance into an empty space in the material editor where i can tweak the settings for it.
or creat a sphere round your whole scene flip the normals and apply the picture as a texture to that and edit the uv's to get it positioned.
I only really use the viewport background for blueprints.

thats how I do my HDRI's and environment maps...but I'm trying to do a composition (stick a 3d model in a real world photograph)

hi kingcobra

i think i can help you
you put an picture in the environment slot and set it to the Screen!!!! (render environment, that slot i mean)

then in your car material slot put in the reflection map a fallof map( choose between fresnel or per.) in the white slot of the fallof map add your picture from the background, but in that case use sperical environment

thats all

let me know if you have any questions
