Related to How to get the range of the input - Adobe Support Community - 13090870,
I found a blueprint nodes called 'Get Float Input Desc' and 'Break SubstanceFloatInputDesc', which make me able to obtain Min and Max of the inputs, but I realized that I can only got the Max value from both Min and Max nodes.
I checked the source code of the plugin and found the codes in `SubstanceGraphInstance.cpp` as below.
case Substance_IOType_Float:
K2_InputDesc.Min.Add(((InputDescFloat*)InputDesc)->mMaxValue);
K2_InputDesc.Max.Add(((InputDescFloat*)InputDesc)->mMaxValue);
K2_InputDesc.Default.Add(((InputDescFloat*)InputDesc)->mDefaultValue);
break;
case Substance_IOType_Float2:
K2_InputDesc.Min.Add(((InputDescFloat2*)InputDesc)->mMaxValue.x);
...
I think this is the mistake that we should add `mMinValue` into `K2_InputDesc.Min`.
