Camera exposure and transform

I imported an animated camera and some objects as fbx, but when I render from this camera it comes out very under-exposed.

If I create a new camera, and then fetch the fbx camera transform to apply it to the new camera, I get the same bad exposure.

If I reset the transform I get back the correct exposure. This is the only way I can get it back, but then I can't fetch the animation!

Why does this happen? Can I fix it ?

After the fetch node try to use a blend and turn off scale, the exposure anomaly usually happens because someone scaled the camera.

I hope it helps.

I posted a file there which shows how to apply transformation from fbx or alembic camera to Houdini camera.

Great, the blend node does the trick, indeed the camera was scaled down.

PradeepBarua, I'm looking at your file and I get lost at the Get_anim_from_CHOPs null.

How do I get the data from /obj/CHOPs/OUT to /obj/Get_anim_from_CHOPs ?

Thanks.

**** Actually I'd like to know where this information is inside the help files ****
