My next terrain project

[+Gepard 11,287]

I have finished now the converting the JPG to TGA files for Guernsey island. It is not perfect, but good enough, i think.

The only thing, what me angered are the slight differences between the blue of the sea tiles and the blue of the coastal tiles of the islands. I tried to solve that problem, but i failed.

I mean it's tolerable, I wouldn't let it hinder me from downloading it.

if your talking the brown on the coastline i could understand. but i cant tell any difference myself on blue areas

[+Gepard 11,287]

The brown water close to the coastline comes from the sat picture. This is intended to be so.

The following screenshot shows the problem, which i mean:

If you look directly under the F-4J(UK) you see a straight line which devided the coast tile with the sea tile. This is clearly visible and i found no way to solve that problem. It's the first time, that i have this problem and i dislike it.

Hi,

Could you upload a sea tile and a differing shoreline tile so that we could take a look at them?

[Wrench 9,845]

yes, what Blade said!!!

I've never run into that, meself

Guernsey 3 Tiles.7z

In the zip file are TGA versions of following tiles

 

[Blade 353]

I tested your tiles (both in game and in PhotoShop).

The first screenshot shows your original tiles in the game. The demarcation is clearly visible.

The second shot shows the tiles after I edited the edges of the alpha channels. The result is not perfect, but it looks much better.

When resizing, PhotoShop sometimes leaves a ‘frame’ around the edges of the image, this is what might have happened to your tiles (just a guess, I am not sure). What I did to your alpha channels was covering the ‘frame’. I hope this makes sense to you.

I will try it. Perhaps i will get a better look.

I always thought, that sea tiles must be TGA files only.

But then i played a little bit with Michigan terrain and made the sea tile as JPG.

This is the result:

No difference to TGA files, but with much smaller memory load.

I think coastal tiles and river tiles will need TGA, but for the sea tile itself a JPG could do the job too.

I mean us at the end user level won't know the difference anyway, as long as it works.

so, they still have the alpha channel, right? I didn't know you could do that with a jpg!!!

No, no alpha channel in jpg.

A bit of clarification to be precise. When there's no transparency in the texture (regardless of the file format) and it gets HasWater other than 0, the water bump map effect is applied fully.

TGAs are required for mixed areas, where the ground requires full transparency, while water areas must not have any transparency at all, or can have slight transparency just to obtain a less pronounced water bump map effect.

If you use a JPG for the sea tile, then you must make sure that all coastline tiles have water areas with absolute zero transparency. If those have a little alpha channel value in their TGA textures, then you get the visible edges Blade showed.

Sit rep for my small Michigan fun project.

I made 3 new tiles. It are small towns or big villages (dont know how the Americans call it).

All tiles a made by sat pictures. From altitudes higher 1.000 meters they are looking really good, i think.

Sit rep for Battle of Britain 1960th project.

I'm creating new target areas in southern England, in that way, that i place factory buildings or warehouses at townfiles.

generally town, or township if its really small

im sure theres a few communities that call themselves villages. but none i've heard of (and ive been in 33 states for more than just passing thru an airport) and they would be the rarity

[Wrench 9,845]

"village" I've heard used in some of the Eastern US states (north eastern) Out here in The West, it "small town"
