Lightroom: Is it possible to merge to HDR without metadata?

Hi,

Does anyone know how to auto adjust a rendering in Lightroom?
I tried to merge several exposures into an HDR but it won’t do it without metadata.
Also it seems it doesn’t import HDR files. Is this correct?

Any ideas?
Thanks.
Guido.

Never tried to merge HDRI in Lightroom, but if it requires metadata, then why not to add it to the files?

You mean manually? I’d rather not have to do that. I’m trying to find a workflow that allows me to do quick HDR adjustments for a large amount of images.

AFAIK ExifTool utility can do batch metdata changes.
