Reflection Capture distance is too high

Dear Community,

we have problems with the reflection captures in Unreal Engine 4. We have placed reflection capture actors in a floor (image 1) and the doors that are actually about 200 meters away are reflecting the lamps from image 1 (image 2).

Thanks in advance.

With best regards

Hi Sky -

You can lower the influence radius of a Sphere Reflection Capture Actor and you can adjust the Box by adjusting the Scale settings to best match the hallway you are wanting to add the box to.

Thank You

Hello Eric,

we lowered the influence radius and the scale of the reflection actor (it was made before the post), but the problem is not solved.

You seem to have only one capture actor. This results in your reflections being the same everywhere. Normally you would add at least one per room.

I would recommend looking at the placement of these actor in sample content to better understand the way they behave.

Hi -

To Combine a few things here, Arnage is correct that you should have more than 1 capture actor per level or reflections from the entire level will pull from that one capture actor. Also though, your bounds are outside of your walls. Capture Actors will pull information from distance sources if there is not a stopping mesh, this is how a sky box is rendered in a reflection even though it is not technically within the capture bounds. Try decreasing the box bounds to be inside of the walls of your hallway.

Also take a look at the reflection capture documentation which does a good job laying out how to use multiple capture actors effectively.

Hey Eric,

thank you for the help! We didn’t know that RC actors overwrite the reflection.
