Hey guys!

These are my attempts made to work with vray HDRI. THe prob i always face is that i am not able to adjust the same HDR bitmap at the background(enviornment) as shown in the chris nicholos (gnomon dvd). If i try to apply any other bitmap other than HDR the bitmap is rendred far dull than the usual scene. Amongst the attached images by luck i was able to set up the HDR in the background for evening view. But for day i am not able to do it any how.
So please help me for same.

Welcome tejalvirkar, nice work.

yes, managing HDR is always a troublesome. rendering looks ok, may need to add some more foliage in the background to cover up the horizone area for the first render. the white building in the second one looks overbright, youy have to adjust the rgb value of the hdr file, i think.

Sure, can you post the vray setting you used for the scene and type of light setup?

Welcome to the site Tejal. Nice work you have here...just a few suggestions...In the evening view you can add a treeline at the horizon. For the day view, adding some texture/colors to the white building will make it look more lively, and the reduce the mapping size on the road a bit...

where are you applying the hdri info , in max environment or the vray env?
the day view looks tiny to me , maybe its the road mapping or sthing but looks like a toy city , the evening one has giant rpc shrubs...while scaling them a little bit is fine .. you kinda scaled them up too much thereby distorting the scale of the building... keep on practicing

Tejal, for the horizon, you don't actually need to place foliage using any of the methods you have mentioned. What you can do is simply find a background image that matches the mood of your scene and has a foliage, and composite it as per your level of the horizon. As an alternative, you also get treeline-maps, you can simply place one of those there.
