It is possible in Blender, but I don't see the mechanics behind it

it's just math... the color is clamped against (0.0, 1.0) when it's transformed from float back to int

Then the most possible explanation is that I am doing something wrong with nodes or they do not work as expected

<@250706991515828224> Do you know what is extLightFactor for exterior lighting?

vec4 finalColor = ((standardExtLightingTerm * matDiffuse) + vertexColor) * 2.0) * textureColor;

Where standardExtLightingTerm is (extLightDiffuse * extLightFactor) + extLightAmbient
And matDiffuse is the usual 0xFF7F7F7F -- ie ~ (0.5, 0.5, 0.5, 1.0)
