Have an issue with light emission material.
For simulating a laser beam that cuts into something I use a small tube interscting a cylinder. The tube has a blackbody emission material that casts light onto the surface of the cylinder.
But the light cast is out of center. How much is depending of the angle of the intersection.

Why isn't it calculating correctly? Do I miss something or is it a bug?

Try to play with the Ray Epsilon parameter, it might be related to your scene scale.
If it doesn't help, please upload your scene.

Thank you!
Ray Epsilon = 0 minimized the offset but now its casting shadows left and right. I disabled shadow visibility in ogject tag on beams but no effect.

Anyway - the offset is gone.
