You get to create an old piece of paper and the tutorial takes you through all the steps. You need to know the basics of both Lightwave and Photoshop, though the tutorial is step by step it does not explain where everything is or what things do.
Okay, we'll do a tutorial on heavy texturing now, turning a simple flat plane with a bunch of polygons into an old piece of paper with handwriting on it. 50% of the work will be done in Photoshop, and there's where we'll start. In the end, you'll hopefully have something looking like the following picture.
Lets get going! Start by loading up Photoshop. I'm using version 6 but I'm sure this can be done in earlier versions to. Set the background colour to white, and the foreground colour to black, and then create a new document - 21cm wide and 29cm high.
Select the Airbrush tool, and then change the pressure to 100%. I am using the smallest of the sharp square brushes, look at picture 2 to check my settings.
Okay, what we'll do now is draw a line how we want the edges of our Fantasy letter to look. Put some time in this to get a good result, picture 3 is my creation. Start drawing about 1cm in on the image, and not at the very edges.
Save this outline as outline.jpg somewhere on your hard-drive now, if something should go wrong we are safe. Finished with that part? Good, select the Paint bucket tool, and set the pressure to 100%. Now click somewhere on the outer side of this line to fill it with black, looking something like picture 4. Note, the following picture is smaller than the actual image; it's just to show you what part should be filled with black.
The first map we will create for Lightwave is the Clip Map, but before we need to make sure that the edges are really sharp, and we can fix this by adjusting the Levels. Use the Magnify tool and zoom in a corner of your paper, looking something like picture 5. I zoomed in the lower left corner.
Okay, select "Image -> Adjust -> Levels" and a panel should appear. Use the following settings.
Click OK when you've entered the values shown, and the AntiAliasing is gone, now you can zoom out again to regular size. This is it for our Clip Map. Select "Save As" in the File menu and set the filename to "Paper_Clip.jpg".
Okay, lets get on with creating a transparency map. In the History Panel, the latest action should be the "Levels" one, as in picture 7.
We need to undo the last action here, so click on the "Paint Bucket" action in the history panel; this will remove the "Levels" action. Okay, we will apply a filter to the edges of this paper now to use as transparency later on, so select "Filter -> Sketch -> Water Paper". Set the Fiber Length to 4, the Brightness to 70 and the Contrast to 77, then click OK.
The edges of our paper will now be "fiberized". Save this image as "Paper_Transp.jpg".
Okay, now we need a Displacement Map. Undo the Fiber action in the History Panel and get back to the last Paint Bucket action (like before when we undo'ed the Adjust Levels action).
Select the Magic Wand tool, set the Tolerance to 30 in the Magic Wand Options panel and then click somewhere on the outer black area. This will make a selection that follows the outer line perfectly. In the menu, choose "Select -> Inverse", which will inverse the selection so we are working with the white area.
Select "Edit -> Preferences -> Guides & Grid" and set the Gridline to every 50 pixels. Also set the subdivisions to 1, then click OK. Turn on the Grid from the "View -> Show" menu, but turn off Snap to Grid. What you have now should look something like picture8.
Select the Airbrush tool and set the pressure to 5%. Select a 35 sized soft round brush from the brushes panel and then paint the edges here and there to add some darker areas. Then pick out a vertical grid line that is closest to the middle of the paper, and paint along that grid line. Then use 2 horizontal grid lines and paint along those. Look at picture 9 and you'll know what I mean.
You can change sizes of brushes as you like, but try to get as similar to picture 9 as possible. Also use a big brush, 100-200, and paint all over the image to get rid of all the white. When you are done, deselect the selection and save this as "Paper_Disp.jpg".
Now use the Magic Wand tool again to select the outer black area, and then inverse the selection. Change the Background colour to R: 215 G: 182 B: 131, and the Foreground colour to R: 236 G: 202 B: 142.
Use the "Edit -> Fill" tool and then fill this selection with 100% background colour. Select "Filters -> Texture -> Texturizer" and use the following settings.
Click OK and the texture should apply within the selection borders.
Select the Airbrush tool and set the pressure to 10%, the mode to Color Burn and also select a soft round brush with 100 in size. Then paint here and there within the selected area so it looks something like picture 11.
NOTE: the round ring is just my airbrush tool
Do you remember how we painted along a couple of grid lines earlier when we created the displacement map? Well, the displacement map will make those darker areas appear bumpy in the final image, so in this colour image, we will create what will look like worn edges along those grid lines, know what I mean?
I can't explain every paint procedure I do, so I will leave this up to you. For Darker Red and brown areas, simply change the Foreground colour to what colour you want to "burn" the image with (and remember to keep the Mode of the Airbrush tool to Color Burn). Look at picture 12, this is my final colour image; try to create the same effects with your brush tools.
When you have finished the work on your colour image, save it as "Paper_Col.jpg".
Only one map left to create! The Text. You can use what you want for this, if you want to create a treasure map, or a letter like me, it's up to you. Create a new project with the same sizes as before (Width: 21cm Height: 29cm). Use a White Background and a Black Foreground colour, then select the Type Tool and start writing your text with a good looking font! You might want to keep the text in the middle of the image, since we will be using clip maps and such later on. Picture 13 is what mine looked like.
Note that I also used the Smudge tool to smear out the text after I created it, making it look a bit older (You don't need to use the smudge tool though). Save this as "Paper_Text.jpg" when you are finished.
Okidoki, all texture maps have been created, so lets use them in Lightwave! You can close down Photoshop now if you want to, and then load up Lightwave Modeler. Create a box with the following settings.
Triple the polygons. Create a surface for this object called "Paper" and turn smoothing on, then save this object as "Paper.lwo".
That's it for modeler, at least for now, so load up Layout and load the Paper object in. Place and Rotate the Camera to the following.
Select the Light, hit "p" to get the properties panel and use the following settings.
Next, use the following position, direction and size for the light.
If you render a preview now by hitting F9 it should look something like picture 21.
Enter the Image Editor and load in all the images we made in Photoshop, it's time for some texturing. We are going to start with the Displacement Map, so click the Objects button at the bottom of Layout and then bring up the Properties Panel. Click the Deformations Tab, then the Texture button for Displacement Map, use the following settings.
Click OK and render another test render, it should look something like picture 23.
In the properties panel for the object, click the Rendering Tab and then click the "T" for the Clip Map channel, use the following settings.
The Test render would look something like picture 25 at this point.
Now let's make this look more like paper, so open up the Surface Editor. Set the colour of the paper surface to R: 217 G: 174 B: 136. Next we will use the transparency map to soften the edges and give them a fibre like look, so use the following settings in the Transparency Texture Channel.
Click OK when you're done with the transparency texture and then click the T for the Color channel. Use the following texture settings for the first texture.
Once again click automatic sizing.
When you're done with that one, click "Add Layer" to add another texture layer, and then use the following settings.
Click OK when you're done with the Color Channel, then render a test render, it should look something like picture 29.
Okay, getting somewhere eh? Get in the Surfaces Panel again and enter the Texture Channel for Diffuse. Use the following settings for the first texture.
Click Add New Texture when you are done with the first, and use the following settings for this one. We need an Alpha Layer to cut out the white areas.
Add yet another Layer with the following settings.
If you render a preview now, it should look something like picture 32.
Okay, we are just going to add a few procedurals in the Bump Map channel now to get the final paper look, and then it's time
for some bones.
Open up the Bump Map Channel and use the following settings for the first texture.
Add another Layer and use the following settings.
Okay, just one more layer and the paper texture is finished.
Add a new layer and use the following settings.
If you hit F9 to do a test render now it should look something like this.
Okay, we are soon finished, but lets add some more geometry to the paper by using a few bones. Switch to Top View and fit the paper in the view.
Click the Bones button at the bottom of Layout, and then choose "Add -> Bones -> Draw Bones". Then Draw 4 bones, one in each corner with an angle of about 45 degrees. Look at picture 37 and you'll know what I mean.
Now select "Bone (1)" in the "Current Item" list at the bottom of Layout and hit "r" on your keyboard to rest this bone, then select Bone 2, 3 and 4 and do the same. Before we start deforming the paper, we need to set a maximum range for these bones, so open up the Item properties panel for the bones. Select "Bone (1)" in the list and click the "Limited Range" button, Keep the Minimum range at 0 and set the Maximum range to 3cm. Do the same with the other three bones, but you can vary the range between 3cm and 5cm. When you're done, click close panel. Now it's up to you how you want to deform the edges of the paper. I simply chose a bone and rotated it using the Right Mouse button (Bank); doing so will curl the edges a bit. I also added two bones in the middle of the paper and curled it a bit there to, and my final scene looks like this.
Now, if you render a test from this it should look something like picture 40.
Okay, use the "File -> Save -> Save All Objects", then save the scene somewhere to keep the Bones and stuff attached to the paper. All you have to do now is render this in perhaps a higher resolution and with AntiAliasing. I hope you learned something from the tutorial and I wish to thank you for reading it!
