Problem with RecLights edges

Hi UDN,

We have a Problem with some RecLights, which randomly generate a strong edge line over translucent materials.

These lines appear and disappear randomly when you turn the scene lighting on and off. For example by unload and load the same environment.

Below are two images showing the same Meshes(vehicle), Level (environment), and lighting, but with different results.

We have identified that the line is generated by a recLight (see image) and we’ve tried to find the problem, but we don’t see any strange settings in the RecLight or texture used.

This problem seems to be an engine error. Do you have any information that could help us solve the problem?

Hello,

Thank you for reaching out.

I’ve been assigned this issue, and we will be looking into this lighting artifact for you.

We were unable to reproduce this as described.

Can you please send us a minimal test project that demonstrates this, and include screenshots of the issue in the test project?
