I think this is a Very usefull feature, im currently using the Pascal’s ExplodeBlockToLayer script a lot , i think it will be also usefull to have a feature that assigns a Random color to the Layers on the scene, when i import an STP all the Layers have the same colour, and its helpfull to have them with different colors so you can differenciate between parts
maybe One random color for each main layer and adding variants of the same color for every sublayer
E.g:
1- Random color (40 to 60% Lightness, 80 to 100% Saturation)
1.1 - Hue variant -20° to 20°
1.1.1 - Saturation Variant (avoiding values close to 0 and 100%)
1.1.1.1 - Lightness Variant
