Issue with 3D Default resource pack

[matepor464]

Hi, I started using the 3D Default resource pack and noticed this light bug on surfaces that the resource pack changes (like trapdoors etc.). I realize this may be more of a resource pack issue, but still wanted to report it here in case You can solve it in the shader.

I'm using Iris 1.10.9 with Sodium 0.8.12 on Fabric. Screenshots below.

Indeed. At first glance, it appears that the custom 3D geometry causes Minecraft to use the algorithm it employs for entities (things that are not world blocks) to light objects with nearby lamps.

It could only be fixed if the shader worked in a completely different way and ignored the information provided by Minecraft, calculating the lighting from scratch (which is what ray-traced lighting usually does). Clearly, that is not the goal of MakeUp.
