Is there a way to get nice sort of seafoam greenish color ocean water for a vacation hood without using Voeille's set because I can't get it to work with my dinosaur of a computer. To me seafoam green water means warm water....dark blue water means cold water...and I don't want to swim in cold water and neither do my sims.

I use Gwenke's :

I've see oceans in various places; southern California looks more brown than blue; places with shallow water have the most clear, blue water (SE Mexico) & the Caribbean looks turquoise (due to shallow water andwhite sand).
So for a warm place I want to see turquoise water; but would love OPTIONS for my scummy places. Like when Mount St. Helens caused trees/cars/houses to float down rivers. Pollution, fire, floods, YEA!

Water reflects the sky so blue water is bluer under a blue sky. Green tends to be caused by algae and plant life not temperature.
We have water every shade down here in Australia, it's not cold.

I can't figure out how to use Gwenke's. When I place in in NH view it doesn't change anything in NH view. I have the Twiikki water already.

I think the Gwenke's water is the Twikki water ?
It should change appearance for you in NH view .

There is also a pond/lake water recolor for lot use only that changes the surface.

Back to Gwenke's, you have to make sure it's placed correctly to show up in NH view ; or it could be that your graphics card is not supporting it ?

My former pc was Win 98 and it displayed the ocean color correctly.
I was using an older model of Nvidia.

Maybe someone else who is more computer-savvy can chime in here ?

Also, if you post your computer specs someone may be able to figure out why the Twikki water aka Gwenke's is not displaying properly ?

I hope you can get it fixed ... I love using Gwenke's recolors in my custom vacay hoods.

When you pick it up from the catalog, you should see a huge blue flat square which looks ugly up until you dive it into the water and then it should look beautiful. Try moving the mouse around, rotating the object, etc. Take a picture so we can see what's happening in your game.

If this is the overlay that I have used before https://sims2artists.com/index.php?topic=4431.0 make sure your pc can run it, this is a huge texture. I use to use it and removed it due to pink flashing. But if you are going to use it you will need your settings on high/your pc will need to be able to handle it. I have found that once I had a better pc with a better graphics card that the sea water was naturally very pretty without adding anything.

Also if you disagreed with me I am not sure on what point, the water here in Australia is warm and it is often blue. This is a factual point. As to the game you can make your water whatever colour you like. But water is intensive and you are asking more of your pc by adding an overlay. in fact just having a lot of water in a hood ups it's texture requirements. That and trees.

I disagreed with your statement that the water is blue because it is reflecting the sky. Is the sky blue because it reflects the water? Neither.Google it.Anyway, no biggie

I live in NE Florida. Although it is hot here and our ocean is warm, the Atlantic Ocean is murky in color off our coast. I have been all up the eastern coast of the USA into Canada and most of the ocean is the same, except when you get to South Florida. South Florida (around Miami and the Florida Keys) have whiter sand and blue Ocean. Even in NW Florida (gulf of Mexico) there is whiter sand and blue Ocean. The best I remember from Science class (too many years ago), the deeper the depth, the bluer the Ocean is.

Florida is warm or hot year around even South Carolina is I live in Southeast Michigan and in summer time it gets REALLY HOT here most summers it can reach temperature of up to 90-120 Degrees F I have lived here all my life. I don't know what the heck google is talking about no it gets way hotter than 80 in the summer here especially in the city
