We will use a water material for example…
Open the water material
Where the end of it all is (the final plug node) you shoudl see something plugged into OPASITY
If you right click anywhere in the grid and type “” you will see 1 node available.
You click that one to add it
Then, simply hold CTRL and move the line from the OPASITY on the final node to the OPASITY (in) on the node. Out from node to the final node (the only place for it is in)
You might have to do with base and … the other one, i forget what one it is off the top of my head.
Sometimes, causes funny thing to happen to the materials, like, it might turn all grey after compile shaders. In case, your S O L and need to remove the node and put it back the way it was.
I have run into already several times … most the time it works tho.
EDIT:
It maybe 1 of the 3 things, it maybe 2 of the 3 … it maybe all 3 nodes. You have to test to find out. For example, when i tested with the ocean project, it was only Opasity. When i connected the other nodes, it messed everything up real bad.
