Mentalray lightmap and camera film offset issue

[hyungeun-kim]

with my project, i use mentalray... so it create lightmap
almost, it work nice.. so i'm satisfied with that.
but, sometimes i have to use camera film offset for private purpose.
at that time, lightmap and film offset collide each other.
it looks like film offset make scene components... but lightmap is not moved.
so objects and lightmap are not overlapped rightly.

I have the same problem!!!

Using mental ray;  we cannot combine a light + texture, with the rendering camera's "Film Offset" attribute or there's a freakish tin-foil artifact. 

Troubleshooting now! This is a serious issue as it affects all stereoscopic rendering...

A workaround is to use "film translate" instead of "film offset".  Wish I had known that a long time ago!
