STILL Don't Have Terrain Tools

You're probably just missing it . I have hard time locating stuff because...idk, my focus is awful. Share a screenshot.

It should be there. In build mode, on the screen where you choose walls, doors, etc look for an icon of a shovel in a pile of dirt; should be somewhere around the pool & tree icons. That's the terrain tools option.

I have the Terrain Tool. Just not the paint

Dont have the terrain paints? Share a screenshot! :/

When you click on the terrain tools symbol, it should open to show the terrain paints, the eraser tool and the terrain tools. Mine does, I just checked it. I was confused at first because it only shows the shovel symbol where the paints used to be, but by opening the terrain tool, I found the paints as well.

When I place a house onto a lot that I've downloaded, the terrain paint disappears. And yes, all my Sims games are on laptop, so everything is on Laptop Mod, if that part helps

I'm sorry, I haven't used a laptop, so have no idea why laptop mode would do away with the terrain paints. All of the houses I make, with very few exceptions, are downloaded from the Gallery, and I've never had the terrain paints disappear. Sorry I can't be of more help.

Disable laptop mode. I almost never recommend it even with terrible computers, it causes more issues than it solves. See if that helps.

Thank you Zeldaboy180!

I play sims on a laptop on ultra, with no lag whatsoever. And I have terrain paints. It's not due to playing on a laptop :D However, since you havent shared a screenshot, its harder to help you. Try that and see what it does.
