By the way, can somebody tell me something about the color depth of OpenTTD gfx?
And if there's a color palette.

Graphics can come in two colour depths, 8bit and 32bit. The default depth is 8bit which requires a palette (from Purno's drawing tutorial - you find much more useful graphics stuff related to (O)TTD(P) graphics in his signature): http://users.tt-forums.net/purno/PDT/re ... lette.html

Briefly : OpenTTD supports both 8 and 32 bit color depth.
Yes, there is a palette for 8 bits. Given time, I can provide it.
I thank you for the effort. But remember, we would not want to let you do all the burden of the task.
In fact, honestly, it should be on our shoulders.

Thank you, planetmaker & belugas!

There're different options:
1. We rescale the graphics (buildings, trees but no ways and bridges (it's easier to create new graphics here for them)) and you integrate them.
2. We give you all source graphics, so you can rescale and modify for OpenTTD yourself (i prefer to rescale myself).
3. We show you the source graphics and you mark all graphics, you need - we'll rescale them.
4. You have better ideas. Post them! :)

After all i can show you three sample graphics (32bit).
What do you think?

If you prefer to scale the graphics yourself, I don't think anyone from OpenTTD is gonna object ;)

Again, these graphics rock, and would be very cool to have in OpenTTD.

Looks beautyful. Such a set should be possible in 8bit too? The comic style seems to be designed for 8bit graphics (nevertheless your three samples have between 900 and 1700 colours).

Tschö, Auge

Well, the showed graphics were rescaled by resampling, not resizing. It's cleaner but makes the compiling in 8bit more difficult.
Actually i planned to try the graphics in 8bit in the next days. I don't have time this weekend but i'll make it next week, be sure. :)

As far as i know 2x2 city buildings are possible in OpenTTD? So we could use 2x2 tiles for highrises und skyscrapers. Looks much better.

Nice greetings from "neighbor" Hamburg. :P

1x1, 1x2, 2x1 and 2x2.
However, I'm not sure whether the sprites should be cut into single tiles for coding related stuff. I bet a TTD NewGRF coder could tell that.

here's those buildings in 8bpp, with some minor dithering

I don't think they look too bad

I've also made the city roads, all but the slopes.

I'm wondering, too. It's 8bit but not with the TT palette.

And they're a little bit too squashy. Please wait till monday - i'll have sharper graphics then.
Um... So i could make all graphics in 32bit and somebody from here could compile them in 8bit? Easier for me. Actually i don't know how to compile in 8bit TT palette... :oops:

I directly applied the TTD pallet, but I didn't check for reserved colors being used.

These graphics do look very good :) although I don't know for sure if a comicy suits OTTD that well but it sure is worth a try.

If you convert a image to the TTD palette and you're not sure you have non action colours only you can always run palconvert (search) over the image, it will replace all action colors to the nearest non-action color. I personally would like this set to be a 32bpp replacement though, I don't really like the rendered 32bpp graphics.

Contrary to XeryusTC, I do think they'll fit very well with OpenTTD, as long as they are on a set by themselves.
Mixing both normal and comic set would indeed be strange and odd, to say the least.

And in my humble opinion, 32bp should be the way to go, since more freedom can be achieved as much as color placement, rescaling and such.
Note: I am definitively not a graphic artist. By far. So my opinion stands for not much...

I would go for the 32bpp, at least it would be useful for something :)

And I guess it would be very limiting to squeeze whole set into 8bpp.

Very much indeed!

If the choice is between 8bpp and 32bpp, I'd advocate 32bpp, too. Downscaling is always easier possible later on, if still desired, upscaling not.

Two thumbs up!

I would much prefer it as a 32bpp too. And like planetmaker says, it is easier to convert them later to 8bpp.

You guys have done a great job, the graphics look great.

Well, we should start a new topic in OTTD graphic section.
I have three sharper and flipped graphics for you (32bit, no OTTD palette). Three of hundrets. :D

I really hope there's no limit for the number of city buildings.
Feel free to modify little details! The copyright is by me if not otherwise reported.

What about animated buildings?

Apart from action colors (pixels which have a pattern of switching colors), I haven't seen any animated buildings in OpenTTD yet...

You did. There is an building with animated elevator in the original graphics. And cinemas and theatres in TTRS have animated signs too.

Aye, true, NewGRF supports animated buildings. I remember Zimmlock's exploding Hospital now :D
