WaterProDaytime with color gradient

Questions & Answers
1

Hello,

I created a mesh with a WaterProDaytime material. Now I want the refraction color of this material to behave like a gradient. For example the left side of the water mesh is brown and the right side of the water mesh is blue and between those ends there should be a continous color transition. Is this possible or did I choose the wrong approch to do this task?
In principle I want a continous color transition in the water color. The WaterProDayTime material is not necessary, but it would be beautiful because this material looks so good.

Thanks in advance!

I solved this problem myself. I have performed the following edits to the FXWaterProShader:

  • the struct v2f has now the fixed3 color : COLOR0 value

  • in the vert-function:

     fixed3 color_left_side = fixed3(0.5, 0.2, 0.1);
 o.color = color_left_side+v.vertex.zzz*2;

this code is for the z-value dependent color transition of the mesh

  • In the frag-function under the HAS_REFRACTION line I added these lines:

      half4 v = half4(i.color.x, i.color.y, i.color.z, 0);
  half4 refr = tex2Dproj( _RefractionTex, UNITY_PROJ_COORD(uv2) ) * v;

Now hopefully you can see a continous color transition of the water mesh from brown to black :slight_smile:
