sketchup - vray - .exr question

[3dgraffiti]

Hi everybody, this is my first post to any forum. I use sketchup v8 and vray 1.49

I rendered and image to a .exr file, however my background image came out transparent when I opened it in photoshop. The background is a 32 bit HDR sky and is set in the BG Color, texbitmap slot. Any help would be appreciated!

Thank you,

John

In the VFB channels options - deselect the "alpha" channel, then your render should save with the background.

i'm still having some troubles with those exr-saved large images..
i found that if i don't save the maps and keep the the "single frame" calculation mode of IR and LC maps, it renders fine, but has exactly the same memory limitation with the standard VFB render mode.
if i save maps things get better on the memory side, but i found strange color artifact such as zones rendered in flat red, or flat green or flat blue.
in particular i found this problem popping out every time i try to use a saved IR map using "from file" mode.
so i'm rendering with saved LC maps, but still using "single frame" method for IR.
how can i solve this problem? did anyone find a good tutorial on the whole maps saving/loading stuff?
