So basically I am trying to make a shader that is masking out clouds with a white mask. I somehow made is mask out all the black with opacity mask, but the masking is making the edges of the clouds very hard, which make the clouds not looks like clouds... any tips?
Hello! The Opacity Mask port only accepts values of either 0 or 1, from full transparent to full opaque respectively, so if you want to use a value range between 0 and 1 you should use the Opacity port instead.
More information is available in our Wiki Manual in this regard.
