Have you ever tried to understand the logik behind values in the sliders – well I tried to and this is my report from travelling through an alien world.
Well – let
s start with a simple thing. Zero means – its zero, nothing, a singularity in the middle of nowhere. 0 Alpha means – no Alpha. Alpha ist deactivated. Alpha 1 means Alpha is fully activated. You think you understood the logic behind it? Well let`s try to set our gloss values. 1 means no effect (deactivated) and 0 full effect – everything vice versa.
You want to scale a texture 5 times bigger – use 0.2 in the size texture sliders. You want it 10 times smaller – yes, multiplicate with 10. Using reziproce values seems to be very popular among programmers, but it`s frustating users. Scaling in Subsurface Scattering works the same way – everything vice versa.
Look and feel in Blender has to be taken verbaly, because look and understand is not allways possible. For instance the Falloff slider. A chart from 0 to 10. You might think that 0 is nothing and 10 is very much. Almost right. From 0 to 0.99 the value increases in a quadratic way, 1 means linear and 5 maybe E=mCC .
There might be good reasons to make things like they are, but I`am teaching Blender at school and these things drive me crazy.
