Hey again TCNGO,
I’m checking out your images and wondering if you have downloaded the update for the pack? It appears like your foam is still only populating around the edges of the river and it was updated to populate across the entire surface of the water. There is a checkbox still that allows you to switch between how the foam populates and also how the distortion is created. Here are the updated release notes and dates of the updates
PACK UPDATED!! - 08/03/2015
2. Water- Fixed water distortion issue creating a double image on assets in front of it (gave option to use refraction instead of distorted screen image)
3. Water - Updated water with tessellation to deform with the speed and intensity of the river
4. Water - Look into screen space reflections with the water to look correct (Turned off screen space reflections for the time being, but can be turned back on in master_river_material)
5. Water - Exposed Parameter for reflectivity of water surface
6. Water - Adjusted Foam Population to work using either depth based population or a simply addition overlay on top of the water surface
PACK UPDATED!! - 09/03/2015
2. Water- Fog Plane issue in distance (This is caused when the user has both Exponential Fog and Atmospheric Fog in their level. In order to fix the problem seen with the translucent material, the user has to disable either 1 of the two fog options so that there is only 1 fog being used)
3. Water- Add spline point numbers floating above each spline point to help with scaling the river
Would I be able to ask you to select the River spline you are using and off to the right where the BluePrint properties are, can you hover over the material and verify which material is applied to the River Spline?
Then if you could open up that material instance and take a picture of your settings for the material instance so I can help trouble shoot what settings you might need to change to fix the issue. Thanks!
We’ll get this sorted out
