Thanks for the report, not sure we consider this a bug, but I'll leave it open for further investigation.

Yep, I am also not sure, if it is a bug, but for me it hard to imagine, that it was intended. More like accidental.

Soft min/max doesn't make sense in this value field. It should behave like other mathematical nodes and accept arbitrary numerical input. Use case for it would be Value set by the user and Min and/or Max values driven by an input, eg a texture.

I also think removing the soft min and max is the best approach. It's not currently possible to make them dynamic, and the whole point of the node is that the value input has a larger range than the min and max inputs anyway.

@JacquesLucke, are you okay with removing the soft range?

I agree, that it is better to remove soft limits than to leave it as is, if there is no time to implement smarter behavior.

But, soft limits according disconnected input will be sane too, if we speak about case, that @BartekMoniewski shown.
I mean no limit for min, because we don`t know what is there and soft limit to max, because there is no point to set higher value manually.

Maybe we can make the soft limit more dynamic in the future (mainly needs a socket->node pointer I think). For now I'm fine with removing the soft limit.
