Spurred by your encouraging comments, I began a new route yesterday. Problem: my river contained no water. Where was the water effect layer? Fortunately someone on this forum gave me the following instructions:
1 Left click the + symbol next to Effect Layers in the Layer Palette.
2. Give the layer a name - eg Water Test and select water for the drop down Effect Type
3. Enter the colour codes (eg Red = 0.0000, Green = 0.5000, Blue = 0.750.
4. Click the link Apply and then click the Tick
I tried to follow this, but I failed to spot Effect Type and I didn't want a colour, I wanted the reflected sky feature that I thought was default.
Anyway, having done my best, I received the following message:
This effect type is disabled in game settings. You may continue to edit this effect, but the changes willl not be visible in the world.
So, having read you can have multiple water layers, how do I get one?
