I am rendering an image with some trees, but when I export as a vrimg file, convert to exr and open in photoshop, the tree has some fuzz around it. I am rendering at a decent size, 2550x1700 and have checked affect background, so what else can I do? Also, if I render as a vrimg, how do I get the render passes like zdepth and alpha? Thanks

I've never tried to render with a HDRI before and am having serious issues. The HDRI i'm using is supposed to be a blue sky with some clouds, but the render comes out as though it were dusk. I loaded the HDRI into the material editor and instanced it into the max environment tab, and the vray environment tabs. Please help. Thanks.
