how to composite carpaints and such shaders in Vray??

[angad]

can any1 tell me how to composite reflective shaders in vray... everytime i try to composite it on vray the carpaint renders transparent.....

[instinct-vfx]

cause your environment is not spherical but screenmapped the reflection would be the same as refraction...easy as that

so shall i use an hdri image or just make this picture spherical???

You shall to use a HDRI to make a reflections. It is good to use a spherical HDRI. And for background use a photo.
