Gaussian blur - siamirold - 03-24-2026
This is a Gaussian blur shader and a collection made by it, the Gaussian blur is smoother than the native blur filter.
This is a very performance consuming shader. Please lower the value If lagging
Using the shader, I created an awesome collection.
It achieves a myopia like effect. It looks like you have watched too many porn and make yourself can't see anything clearly anymore. XD
Please note that collection is a full screen effect.
Besides, I uncensored the feet and the armpits to demonstrate my mercy
Any advice, pls come to Discord and DM Eilysia
Keeping censored and have fun !
RE: Gaussian blur - Wombatant1 - 03-24-2026
this thing devours gpu resources, but [gaussian blur] joined with bodyline clipping is one of the best combinations that i've tried in hotscreen
RE: Gaussian blur - bobbob9999 - 03-27-2026
I downloaded, and added myopia collection, but hotscreen doesn't enable the "edit collection" button with it turned off, and with it turned on my entire screen is blurry so I can't see the hotscreen controls for the collection.
What's the solution?

Is there a way to increase the blurring?
RE: Gaussian blur - whizzkid - 04-01-2026
I played around with it a bit and added a toggle --> with the "Blur Regler" line you can adjust the blur.
