Since time immemorial the default mat's bump map amount has defaulted to 30 instead of 100. I can't even guess how many times I've had to set the value from 30 to 100 throughout the years.
Why is it 30 and not 100? Sure, the value is a multiplier that goes all the way to 999, unlike most of the other map slots - but so does "specular level", which defaults at 100, instead of 30.
Could you please change the default amount of bump map slot from 30 to 100?
