Transparency Glitch

Question

Hey all, I’m working on a VS battle-style anime image for a client site [removed by moderator] and I’ve run into a technical issue with Motion Blur in Photoshop that I can’t seem to fix.
 
Whenever I apply Motion Blur to a character layer, it creates weird semi-transparent edges, almost like there’s an unwanted alpha channel effect. Even though the layer has full opacity, parts of the blurred area appear faded or completely invisible against the background.
I’ve tried:
 
Converting to a Smart Object before applying the blur – no change.
Disabling anti-aliasing and checking layer masks – no effect.
Rasterizing the layer before blurring – same issue.
Changing color modes (RGB, CMYK) and bit depth – nothing fixes it.
Toggling Photoshop’s GPU settings – slight improvement but not a real solution.
 
I’ve been watching multiple YouTube tutorials, but I can’t find anything that specifically addresses this blur transparency bug. Has anyone else encountered this? Any suggestions would be greatly appreciated!

Hi!I am not sure why this is happening, but I do have a suggestion you might try. Create a layer and fill it with 50% gray, and set the Layer Blending mode to Overlay or any other blending mode that works with your image. Create the Motion blur on that Layer and see if it gives you the effect you want, or if you are still haveing the same issue.Let us know?Michelle
