View Full Version : Masked textures in classic Unreal Tournament
08-18-2005, 01:56 PM
Hi, I have a question about masked textures in classic Unreal Tournament. I've read that if a texture is imported as masked, color index 0 is set as transparent.
I've tried to import some textures to Unreal Tournament using this feature, but the only textures that show up with transparency in game are the Chat icons I made. However, I also want some parts of the actual skin to have transparency.
So, here's my question: Is it possible to have textures with transparency on UT player models? Should I write a script file or is there something else I should do to get it to work? I have no idea why it works for chat icons and not for the other textures I tried to import.

Ok, I think I've discovered why it isn't working. The model's polygons need special flags like Masked, Translucent & Modulated in order to get special effects to work.
Since the textures are for a custom model I'm trying to import, I'm trying to find a way to do this.

I have a small utility at home which lets you set all the various flags on a UT model. I'll be home in about 10 hours, I'll see if I can find it and i'll mail it to you. Whats your email address?
Never mind, got your email addy from your profile.

Im home and I've mailed it. Have fun!
I dont know what version of MAx your using but this might be of interest:

Your gmail account doesnt like .zip files. Do you have another email address?

Sorry for my late reply I was away for a short holiday this weekend. It would be cool if you could sent the zip file to: email@example.com

Yeah, I finally solved my problem! The textures have transparency now, but it was quite a hassle. Because it might be of some use to others, I will try to explain what I did to get it to work. /images/graemlins/grin.gif
I exported the model from Milkshape to UT's Skeletal format (.psk), so I didn't have to animate the model myself and could use the animations included in the Advanced Models Support add-on. However, UnrealFX can only import and export UT's _d.3d format, so I couldn't use that tool to change the face flags, and Milkshape has no support for it at all. I searched the web for other tools to do the job, but they all needed Windows 2000 or Windows XP and I'm still using Windows ME. http://boards.polycount.net/images/icons/poly114.gif
Anyway, I did find the following workaround:
Because the model was imported with Advanced Model Support, I could add the following piece of code to my Skin info file:
<font class="small">Code:</font><hr /><pre>static function SetFX(actor SkinActor,Class<GenericPlayer> PlayerClass)
SkinActor.Style = STY_Masked;
static function UnsetSkin(actor SkinActor,Class<GenericPlayer> PlayerClass)
SkinActor.Style = STY_Normal; //reset to default
With this script the in game model had transparency, eventhough I wasn't able to set the face flags in the .psk file itself. However, the script didn't work in the player selection menu. I could solve this issue by using a separate selection mesh in _d.3d format (exported from Milkshape) in combination with UnrealFX.
It's not a pretty solution though, because it's not recommended to change display attributes with a script and I'm not sure if Valhalla Avatar supports it.
ermm i remember that pshop didn't seem to do the 0 index thing right. The only way I got it working was to use painshop pro to do the index thing.

@Ruz: I used photoshop to save the textures and I didn't have problems with the "index 0 thing". /images/graemlins/tongue.gif I did the following:
I erased all the parts of the texture that needed color index 0, using the background eraser tool - leaving them completely transparent. I then converted the textures to the indexed color mode. But before the textures are converted a menu pops up where you can change the settings: now you only have to tick the transparency option. The parts of the texture that needed color index 0 now have color index 0. Finally - you can change color index 0 to any color you like using the color table.
Another option would be Erik Neve's tool Bright 1.83 (http://dl.fileplanet.com/dl/dl.asp?/polycount/tools/ut/bright183.zip) for high quality palette reduction. It's a command line tool which can covert multiple textures in one "single sweep" to 8-bit palettized format. It also supports index color 0 - it changes a specific pink color on your texture to index 0. It also has an extra option for mipmapped textures. I never used it though - because I still don't know how it works. http://boards.polycount.net/images/icons/poly122.gif

I've done some more beta testing with the scripted skins and it's indeed an unreliable method. The parts of the skin that should be transparent sometimes become visible again - atleast when there are several player characters running around using this method of transparency. The lighting on the mesh parts with transparency is also very strange - sometimes these parts look almost black.
I really should flag those polies in the psk file, but I still haven't found a tool that would work on my windows ME system.
* Edit *
Yeah, I'm happy! I've found an experimental tool to set face flags in psk files. I had to compile it myself, but it worked. The model has working masks now. For those who are also interested in the tool, you can get it here: Download pskhack from the beyondunreal forums (http://forums.beyondunreal.com/showthread.php?t=123814&highlight=pskhack)
