KSPE Renewed custom block light assistance:
1. How to remove blocks that I don't want to shine?
Erase the block texture to remove the glow effect for the block!

2. How to make the beam glow?
A pixel emits light when the material's single pixel alpha value (opacity) is 252 (fc in hex) or 99%.
And the luminous brightness is determined by one of the largest single pixel rgb values.
(Rgb black all 0, even if you adjust it, it will not emit light)

2. How to make a metal box reflect light?
When the material's single pixel alpha value (opacity) is 249 (f9 in hex) or 98%, the single pixel metal is reflective.
And the metal reflectance intensity is determined by the rgb block map.
(white rgb all 1, for specular reflection)
(black RGB is 0, even if you adjust it, it will not reflect)

2. How to make a non-metallic box reflect light?
Single pixel non-metallic reflection when the material has a single pixel alpha value (opacity) of 247 (f7 in hex) or 97%.
It must be very accurate, otherwise it will not be detected!
