View Full Version : Wanted: Ut2004 Water Tutorial

4th Jun 2005, 07:51 PM

I’m been working on trying to get the basics of UnrealEd2004 down and make my own map for some time now. I’m able to make “a basic room” but now I’m trying to fill that pool with water.

I check out Freon’s tutorial at:
And I thought I was doing great all the way up until the point where the author says:
“Because we don't want to cover the whole surface with it, we'll use an alpha channel. In a Graphics Application like Paint Shop Pro or Photoshop, open your moss image and create a new mask (see screen shot in PSP).”
Right there I completely lost everything.
“An alpha channel is used to vary the transparencey in a image. The image is opaque where the alpha channel is white.”
Pretty good explanation of what it is I thought, but then he goes on to say….
“…. Draw some stuff on the alpha channel. You'll have to save your image in a format supporting alpha chanels (.TGA). It will be store inside the file. In PSP you have to use the Save in an alpha channel in the Mask menu.”
Um…. “Draw some stuff”? wha…what does that mean? Draw what stuff? Draw red stuff? Draw blue stuff? Draw green stuff…? What stuff am I drawing and where do I draw it at? For one thing when I open up that file in PS7 I get almost what he has in the picture…
I guess I’m just slow at this stuff. I was always a gamer, but never wanted to design anything of my own up until a few weeks age. I am not mad at the author of this tutorial at all in fact, he got me further than 2 other guys.. but I guess it’s just kinda frustrating..
If anyone has the time or anything and wouldn’t mind helping me out, please let me know.
thanks so much – and great website

That stuff's a bit advanced if you're still learning the basics. I wouldn't worry about it for now.

Yeah I understand your point I’m still learning the basics... but my point is that if I want my map done correctly, I’m going to need to know how to do this eventually. In other words, I’d rather learn it now then later.

Let me know what you think.

Well, you'll need Photoshop or some other program that can handle alpha layers, then I'd read this: http://udn.epicgames.com/Two/MaterialTutorial (including all the subcategories at the end).
