lor1 input socket. Then connect the Color output of the last Burn node
inside the DENSITY frame to the Color2 input socket.
17. Drag the Color output of the Soft Light node on the right border of the
group envelope to create a new Color output on the interface.
18. Go to the SLOPE frame, click and drag to the left border of the envelope
the Fac socket of the upper Add node. Rename the new input as
Snow_amount and drag and connect to it also the Fac socket of the bot-
tom Add node.
19. Go to the DENSITY frame and drag the Vector input of the Mapping
node to the left border of the envelope. Move it up by clicking on the little
arrow icon and press Tab to close the group; rename it as Separator .
20. Connect the Object output of the Texture Coordinate node to the Vector
input socket of the Separator node group and its Color output to the
Fac input socket of the Mix Shader node. On the group interface, set the
Snow_amount value to 0.350 .
Adding the atmospheric perspective
The very last thing we can do to improve our material is to append the
Fog_underwater node group from the 1301OS_05_underwater_final.blend |
Nodetree file. Rename it as Atmos_persp and paste it just before the Material
Output node. Then press Tab to open the group and by going in edit mode, set the
Multiply node value to 0.010 and the color of the Emission shader to R 0.078 , G
0.133 , B 0.250 .
