Hello,
I followed the YouTube link below to create a Substrate Material, but the snow glint effect doesn’t seem to be working.
Even after recreating the material multiple times, I still can’t see the sparkling (glint) effect on the snow.

I’ve adjusted the project settings as shown below and also entered the required commands in the console.

The screenshots attached show the current state where the glint effect is not visible.

If you happen to know a solution, I would greatly appreciate your advice.
(My English isn’t very good, so I used a translator.)

Try using the SMF_GlintConversion function before the Glimmer Density input. It’s not public, so you can only find it in the Content Browser within the Engine > Content > Functions > Substrate folder.

I also recommend using a Glint Density value below one. Generally, I advise turning it into a parameter and tweaking it in the instance to achieve the desired result.
