How to make foam in T3D1.1 Beta2 - LOGGED

#1 I couldn't get the foam working, still testing it myself being that 30% of my mission is water based.

#2 I do some more experiments and found it's more like some shader compile problem,although still have foam rendering problem(The foam will appeare with some "colour lines" at short range.).
I did some hot(ugly) fix to that.
Note:after the modification,only the alpha channel of foam.png will be used in the shader.
from

float4 foamColor = tex2D( foamMap, IN.foamTexCoords.xy );
foamColor*=tex2D( foamMap, IN.foamTexCoords.zw );

to

float4 foamColor = tex2D( foamMap, IN.foamTexCoords.xy ).aaaa;   
 foamColor =   foamColor * tex2D( foamMap, IN.foamTexCoords.zw ).aaaa ;

form

foamColor.rgb *= FOAM_OPACITY * foamAmt*foamColor.a ;

to

foamColor.rgb *= FOAM_OPACITY * foamAmt;

#3 Probably not worth marking this post as resolved if it's not doing what it should 100%, afterall the fix is only partial?

#4 Logged as TQA-782 for the QA team to verify.

For clarification, this is not on River water objects, right? But on waterblocks.

#5 No,it's on waterblocks, both waterblock and waterplane are affected by this issue.

#6 Cool! Thanks for the clarification!

#7 Bump
The problem also exists on River objects.

Edit:
Forget this. Problem does NOT exist on river objects!!

Edit 2:
If you set the values for foam according to this, you can see that it will be rendered over the waterblock or river object.

foamSpeed[0] = "0";
         foamSpeed[1] = "0";
         foamTexScale[0] = "1 1";
         foamTexScale[1] = "3 3";
         foamOpacity[0] = "1";
         foamOpacity[1] = "1";
         overallFoamOpacity = "1";
         foamMaxDepth = "0";
         foamAmbientLerp = "0";
         foamRippleInfluence = "0";
         whiteCapAmount = "50"; //Absurd high

The problem is imo after observing and playing with the different values that there is no collision detection with the surrounding terrain or objects which are partly in the water and therefore not generating any foam as you would expect at such parts.
