[TUT] Quanons Tips on Skinning/Texturing
In this thread I'll attempt to show you some tricks I use in Photoshop to create skins/textures for your weapon models and other 3D things from the Kotor game.
Allright, first tip.
Getting your UVW-map of your model into Photoshop.
For G-Max users this is very simple: Take a screenshot.
Start photoshop, create a new empty file and just paste (ctrl+V).
Use the Crop tool (C) and drag a box around the UVW-map.
Hit enter and all the garbage around it will be deleted, your file will also get resized automatically.
Now create another new file, set it to this size: 512x512 pixels or 256x256.
Then use the Movel Tool (V) to drag your UVW-map into the new file.
Now it will not fit good, to solve that hit Ctrl+T to activate the Transform tool.
You'll see these small squares at the edges, you can drag those around.
So use'em to make it fit, hit enter to confirm the changes and your done.
If you get a bit confused/ freak'n out on this tool hit Esc to exit it ;)
Like that you won't get stuck :lol:
3Ds Max users:
First go the Edit window in the Unwrap UVW modifier.
There go to Tools => Render UVW Template.
You'll get a new window. In there set the Height and width to 512x512 or 256x256 pixels. Down below hit Render UVW template.
Again a window comes up showing you the render of the UVW. At the top left is a Disk icon. Hit that to save your UVW-map.
In the browsing window set it to a location you'll like it to be saved and set the file type, if you choose JPEG, you get an extra window again :p
In there its just to set the quality.
Thats it, you now have your UVW-map ready to be used in Photoshop/Gimp or Windows paint if you insist :lol:
With this tip I want to show you how I do razor sharp nasty cutting blades xD
In this example I used a one of my own modelled weapons, which has this spinning blade, lovely.
Ofcourse I made a nice UVW-map using the steps from above.
Now start photoshop, go to File=> Open. Look up the UVW-map.
When that is open I go to the Layers palette. I grab and drag the Background layer, to the NEW icon, just next to the trashcan icon.
Like so you get an instant copy of that layer.
Now alter the modus of this copied layer to Screen. You'll find that at the top of the palette.
Good, to make our blade look like steel/ metal I downloaded a plain photo of... metal :p
This is a good site for such things: CLICKY
So I opened it in photoshop, using the Move tool (V) I dragged it to my UVW-map:
Its to big, so using the Transform Tool ( Ctrl+T) I scaled it down.
I used the top left little squarre and holding down shift I just dragged.
Shift helps to keep it uniform, width & height are being kept the same scale compared to each other.
Once content with the size hit enter, if your not happy hit Esc to leave the Transform tool.
Okay, now I'm going to add the sharp edge of the blade. To that quickly and easly, I used the Pen tool (P) http://i129.photobucket.com/albums/p...ials/Pen01.jpg
Make sure it sets to Paths, you'll find that at the top left of your menu bars:
Then follow the shape of your blade, like so. Just click around to set a point and continue to set more points to create a shape like your blade.
You don't need to close your path, but since I got a round blade I'm going to close it ;)
Now where going to setup our Brush (B) http://i129.photobucket.com/albums/p...ials/Brush.jpg
Just right click anywhere on your map. You should get this handy menu:
Pick a brush with really soft edges, set it to a smaller size, I used 9 pixels.
You could use differant sizes, depending on your model really.
Before we continue make sure you're color is set to white:
Now in your Layers palette, you should see 2 other Tabs: Paths and Channels.
Now I've dragged out Channels, as I like to have that seperate. So don't worry if my screenshots look a bit differant ;)
Go to the Paths tab. You'll find that path we just drew, right click on it and pick Stroke Path.
Another window comes up, set it to brush and hit OK.
Here's my result, the Brush nicely followed our little path, no need to this kind of thing by hand :p
Nearly done, but we need to clean this up a bit.
Go back to Path palette and right click, this time pick Make Selection.
Paths are real handy to make good selections. I'll show more of them later on, as they can be a bit tricky to get used to. Mainly on the curve part. o_Q
This selection is to tight and close, where going to enlarge it a bit.
Go to Select=>Modify=>Expand.
New window comes up, I've set mine about 10pixels.
Now for some magic, do Shift+Ctrl+I to invert the selection and hit Delete.
Result should like this:
Next a quick step forward, this blade should be shiny to some extend.
For that we need a Alpha Channel.
We need to select our blade again, to easly get that, just Ctrl and left click on its Layer.
If you still got your selection just do Shift+Ctrl+I to invert it back.
Do Ctrl+C to copy it.
Go to the Channels palette and hit the NEW icon down below, next to the trashcan. Then do Ctrl+V to paste the blade in the channel.
You could leave it like that now. But the shine effect depends on the black/white in the alpha channel.
Darker = stronger effect
White = No effect at all
I find that its to dark in my channel, to adjust that I go to Image=>Levels.
You'll get this new window. In there you can play around with these sliders to alter the contrast between black/white.
I dragged back the white to the middle make it stronger.
Just play around with it to see its effects on the channel, once your happy just hit OK.
Thats it for these first few tips.
Amazing tips Quanon.Btw,I figured out how to use metal textures myself.I hope to see more tips on texturing from you.
Looks good LordRevan999, glad you got some nice results :)
Might I suggest an alternative method for obtaining precise UV map guides for GMax users? It looks a bit convoluted, but it's relatively straight forward once you've done it a couple of times.
First, download UVMapper Classic from here. This is a standalone EXE (i.e. no installation required) that is free. It has limited functionality, but is fine for our purposes.
Then you'll need to download Xzzy's OBJ export script and the GrabListener utility from here (the "Renx OBJ Tools" link). Make a folder in GMax's \scripts directory and extract the tools there.
In GMax, do the following:
A pictorial guide for the GMax component:
A note concerning multi-object GMax files. The OBJ script only exports a single mesh object at a time. If you have a multi-part model (like a body for instance) you'll have to join them all together into a single mesh before exporting. You should also delete any bones and helper objects if there are any. Just make sure you don't save the GMax file after you do that!
Is the alpha channel black/white thingy the alpha treshold in gmax? thanks.
Thank you DarthParametric, I wasn't aware of any good plugins for G-Max.
I'll include your handy post in the tutorial section aswell :)
The alpha channel, I talk about is part of the skin/texture, its contained in the Targa file.
The 3D model has nothing to do with it.
Thanks, DarthParametric. I just tried that out on a new hilt and it worked perfectly. :) This'll save me time when trying to get a copy of any UV-Map I edit/make.
As for the main tutorial of this thread, it seems very helpful. :D
Still sucks they left that part out, as it makes the working progress flow more nicely, so to speak.
A new tip, this time its all about the blending options.
To illustrate I'll create a sort of floor texture. This could be used
for example in a reskin of an area.
Its just one example, this stuff can be used in various spots of
texture/skin creating. Remember my Sith/ Jedi Quarren, I used this
trick on him aswell
Now onwards !
