Bug with Glowing Layer on Entity with Shaders

This issue (https://mcreator.net/tracker/issue/60696) let to this amazing and awaited feature on 2020.3, but there may be a bug when used with Shaders. Or maybe I'm doing something wrong. 

I created a rideable entity and set the layers like this:

Those are the textures I'm using:

rey_speeder_glow.png

When I test it in the game without shaders, it looks perfect, like this:

But if I turn shaders on, the whole entity becomes black and the hue in the glowing part is changed. I tried different shader packs with the same result.

I don't know if this is out of scope, but I felt like reporting it. There's too little documentation on how to use the feature yet, so maybe I'm doing something wrong.
