SIGC - Transparency
« on: March 07, 2017, 09:14:26 AM »
Formerly called SRGC, but too irregular for that name.

A new game version is out, and with it came a big feature for Graphic Artists: Transparency. Useful for many things, such as tainted glass, shadows, trees, smoke, anti-aliasing,...
Now this causes two tiny issues: On the one hand, a single signal can not compete with a giant building. On the other hand, you can't really show off transparency in an object by itself, you need to see how it looks in the game with other stuff behind it. Therefore, in this SIGC, your task is to create any number of objects that contain transparency, for any pak size and style, and show them through a game screenshot of any (but rather small) size.

I will end this contest on April 17th, then the voting period starts.

The Rules:
  • Who can enter the contest?
    Anyone, multiple times, even if not registered on, who read, understood and agreed to these rules.
  • What do I have to do?
    Create an image that fits the topic of the contest. In this case, a screenshot of one or several objects using transparency.
  • Where do I post my creation?
    Right here. No secrecy this time, it works just like an SMSC.
  • How do I win?
    After the nomination period, we'll start a voting on The image with the most votes is the winner.
  • What about the licence?
    Pick one: CC0, CC-BY 3.0 or newer, CC-BY-SA 3.0 or newer.

Some inspiration:

Just a building with drop shadow.

This is a bit elaborate: The red "STC"-Letters are a frontimage in lightcolor, which enables anti-aliasing.
Click for full size so it can be seen.

Some rendered trees by RedRabbit for p128g (who might still enter with them - but only showing p192c would be boring)

Hello. I was interested in this topic introduced on Simutrans community in Japan.
If there are missing or wrong in in this textmn please tell me.

"Smoke of steam locomotion"

These locomotion have two invisible cars connected forward them and emitting two Different smoke that has transparency at the same time.

I think good point of using transparency is two.
First, smoke concentration decrease as the train speed up.
Before 120.2, images of smoke are mass of smoke, but it looks straight in 120.2.

Second, we can overlay different image of smoke.
This "JHSDF_realsmoke" emit white smoke everytime, and emit black smoke and drain while train powering.
Before 120.2, We have to make hole in graphic so that we can see both graphics of smoke. But I don't have to worry about it in 120.2.

pakset Pak128.japan and many addons
not a real game
