hello devforum, what I am trying to achieve is something like this. I want to make my roads look wet like this whenever it is raining in my game.
how would I go about making this effect with the least lag possibile?

probably a decal/texture or something?

What if you put like a glass part and add some transparency into it then put it in the road, maybe that might work?

I should have been more specific, but I want the road to reflect like in the photo also.

I think there’s a strategy to doing this that involves using roblox terrain water with a transparency of 1. Never tried it but it might work.

However, if someone steps in it, their swimming animation will play.

well that depends on how much of it is showing.

Not true, the swimming animation only shows up if a certain amount of the player is submerged in the water. Otherwise, this will not happen and you can walk normally as long as the water is a very thin layer.

Did a bit of experimenting, this is what i’ve come up with,
what i did was make a custom puddle shaped mesh, and set its reflectance to one, this will reflect the skybox but nothing else, so not perfect but sorta answers your problem

Part I made is her if you guys want to experiment. Please give credit if you end up using it

You can change the material of the part to Glass and Transparancey to 0.25 and Reflection to 0.2.

You could try using viewports as well to reflect the buildings
I tried making a wet road with glass, and it turned out like this. I had to turn transparency up quite a bit, otherwise the concrete texture wouldn’t show much at all.

I dont think theres a performant way of doing this yet.
If you were to stretch decals over it, that would jsut cause insane lag for the amount of decals. Maybe a mesh, but thats still a lot of moving parts that you would spawn in, which could hurt less performant decives. With PBR and custom materials, i saw someone(forgot who) say it could be much cmore possible with those, but im not sure.
That isn’t realistic at all. It’s easy to do this on a realistic method using the Roblox Studio tools.
Can you share how you made that?
U can use app called texturelab 
to make pbr texture, so get a
asphalt texture, or road texture, and after that go to texturelab, here u will see something like this:
get your road texture, and now in library find option called “Image”
drag it to editor, and click on it, and there u will see 3 options, load, reload, remove, u need load option, click on it, and pick your road texture
now just play with sliders on normal map, to get wet road reflections
if it’s too hard, u can try another method, get road albedo texture (color)
and now find wet ground
and now combine road color with ground normal and roughness
boom 
easy way to get wet road

Thank you! That’s a great explanation. I’ll try it later.
