...create that animated water in the official Base map? (I'm not talking about the out-of-bounds water a.k.a the Unity water.)
My plan was to create a lava waterfall and possibly some advanced water like this one (click the eye icon). I first tried using the Unity water and experimented with the given slots, but the results were not good. Then I tried using Animation to animate a texture on a plane, but that doesn't work either - in-editor yes, but not once the map is exported.
Since we are limited to the Legacy shaders and Warmerise doesn't support custom shaders (Shader Graph), what else can be tried/done?
In custom maps, Animation only works with transform at the moment, but I will consider adding all the parameters.
To achieve the waterfall effect you can probably use a semi-transparent shape for a waterfall base and then use the particle system to add the flow, or use the particle system for the whole thing.
