Hello ,everyone !I'm new here.

I'm studying new terrain tool recently, and trying to build a custom shader for it by using the masks exported from COP.

but when I tried to give the mask some color ramp, the parameter all turns into gray and just can't  get them selected.And I don't know why.

just looks like this.


All the nodes are at the ‘obj/geo1/matnet1’ level.


Thanks!!!
