Hi, everyone. We are trying to show the object 3D shadows and reflections. In Unreal engine we adding the shadow catcher and refletions linked with the AR project. But for some reasons appears a strange deformation or grid on the reflexion. This never happened before. Thanks for your time.
Hi,
Are you certain the issue is caused by the Reflection Catcher?The grid artifact you’re seeing looks similar to those produced by additive materials in AR scenes. This happens because, in Unreal Engine, additive materials (materials that add color values rather than replacing them) have nothing to add to if there is no background, resulting in visual artifacts.
Also, remember to set Enable Alpha Channel Support in post-processing to Allow Through Tonemapper, and set the Frame Buffer Pixel Format to FloatRGB in your Unreal Project Settings.

Warmest regards,
