<h1>Car's Shadows for 1.3.x</h1>
|
|
|
|
<p>This tutorial explains how to generate shadows for the cars with "The Gimp".</p>
|
|
|
|
<p><hr noshade="noshade" size="2" width="100%"></p>
|
|
<p>
|
|
First you'll have to create an RGB (uncompressed) blank image (128x128) that you'll name
|
|
"shadow.rgb" in the car directory:
|
|
</p>
|
|
<pre>cars/acura-nsx-sz
|
|
cars/acura-nsx-sz/acura-nsx-sz.xml
|
|
cars/acura-nsx-sz/acura-nsx-sz.rgb
|
|
cars/acura-nsx-sz/tex-wheel.rgb
|
|
cars/acura-nsx-sz/acura-nsx-sz.acc
|
|
cars/acura-nsx-sz/acura-nsx-sz-lod1.acc
|
|
cars/acura-nsx-sz/acura-nsx-sz-lod2.acc
|
|
<b>cars/acura-nsx-sz/shadow.rgb</b>
|
|
</pre>
|
|
<p>
|
|
Then edit the "car.xml" ("acura-nsx-sz.xml" in our example) file to add the following line to the "Graphic Objects" section:
|
|
</p>
|
|
|
|
<pre><attstr name="shadow texture" val="shadow.rgb"/></pre>
|
|
|
|
<p>
|
|
Now launch a race with a player using the car you're modifying, and hit the "P" key before the race starts.
|
|
<br>Select the "F5" view and zoom (with "<" and ">" keys) to have a good view of the car and take a screen-shot with "F12".
|
|
<br>The image is saved in the torcs runtime directory.
|
|
</p>
|
|
|
|
<img src="images/shadow/sh01.jpg">
|
|
|
|
<p>Select the white area and create a new image with the selection Right-Click and "Script-Fu->Selection->To Image".</p>
|
|
|
|
<p>Now use the "Fuzzy select" tool to select the white areas:</p>
|
|
|
|
<img src="images/shadow/sh02.jpg">
|
|
|
|
<p>The result is:</p>
|
|
|
|
<img src="images/shadow/sh03.jpg">
|
|
|
|
<p>Now cut the select area with Control-X:</p>
|
|
|
|
<img src="images/shadow/sh04.jpg">
|
|
|
|
<p>Now select the car with Right-Click and "Layers->Alpha to Selection", then select the "Bucket Fill" tool:</p>
|
|
|
|
<img src="images/shadow/sh05.jpg">
|
|
|
|
<p>Paint the car in black:</p>
|
|
|
|
<img src="images/shadow/sh06.jpg">
|
|
|
|
<p>Invert the selection with "Control-I" and paint it too:</p>
|
|
|
|
<img src="images/shadow/sh07.jpg">
|
|
|
|
<p>Then cut the newly painted area with "Control-X" (this is to have the transperent color made of black).</p>
|
|
|
|
<img src="images/shadow/sh08.jpg">
|
|
|
|
<p>Now blur the shadow with Right-Click and "Filters->Blur->Gaussian Blur (RLE)..."</p>
|
|
|
|
<img src="images/shadow/sh09.jpg">
|
|
|
|
<p>The result is:</p>
|
|
|
|
<img src="images/shadow/sh10.jpg">
|
|
|
|
<p>Now scale the image to 128x128 with Right-Click and "Image->Scale Image..."</p>
|
|
|
|
<img src="images/shadow/sh11.jpg">
|
|
|
|
<p>The result is:</p>
|
|
|
|
<img src="images/shadow/sh12.jpg">
|
|
|
|
<p>Set the image transparency to 80%</p>
|
|
|
|
<img src="images/shadow/sh13.jpg">
|
|
|
|
<p>The result is:</p>
|
|
|
|
<img src="images/shadow/sh14.jpg">
|
|
|
|
<p>Now save the image in RGB uncompressed format:</p>
|
|
|
|
<img src="images/shadow/sh15.jpg">
|
|
|
|
<p>important:</p>
|
|
|
|
<img src="images/shadow/sh16.jpg">
|
|
|
|
<p>The result is:</p>
|
|
|
|
<img src="images/shadow/sh17.jpg">
|
|
|
|
<p></p>
