If I use a float node to blend between two sub materials in octane (Input1 and Input2), it doesn't blend from 0 (input1 completely visible) to 1 (input2 completely visible)... it's always something in between, but never 100%.
If I put everything except Input 1 into a mix material, it works, but shouldn't it work inside a blend material too?
I tried copying everything into a new scene, but same, weird behaviour.

Is that a bug or am I just really stupid?
