    Rendering The LanternBy Erik Brimstedt

    Chapter 1 Basic Scene

    Before we start texturing this Lantern we are going to create a very simple scene for it.This scene will contain of a single box with the polygons flipped inwards, which will act

    like a room. Start the Lightwave Modeler and activate the Box Tool, then use thefollowing settings in the Numeric Panel.

    Picture 131: The Box Tool settings

    Close down the Numeric Panel and press Space to deselect the Tool. Flip the polygons bypressing f on your keyboard. The room is finished; all we need to do is apply a surfaceto it.

    Press q to bring up the Change Surface Panel and create a new surface for this roomcalled Walls, just use the default settings and click OK. This is it for the modelling part,save this object now, you can call it Box.lwo.

    Okay, lets set the lights up, select the Light Item and open up the Item Properties Panel

    by pressing p on your keyboard. Change the Properties of the Lightsource to thefollowing.

    Picture 135: The Lightsource properties

    Close down the Properties Panel when youre done. We need to move, rotate and scalethis Lightsource a bit to fit our scene, so with the Light still selected, activate the Move

    Tool and use the following settings.

    Before we continue, lets change some of the Display Options in Layout. Press d to bring

    up the Display Options Panel, then use the following settings in the OpenGL section.

    Picture 137: OpenGL settings

    Were only using 1 OpenGL light for this scene; since we are adding a second Lightsourcelater on the OpenGL preview might get too bright.

    Keep the Lightsource selected and activate the Rotate Tool, then use the followingsettings.

    Picture 138: The First Lightsources Rotation

    Once youve rotated the Light, press Enter twice to create a keyframe. Next activate

    the Size Tool and use the following settings.

    Picture 139: The First Lightsources Scaling

    Once youre done, create that keyframe. Before we continue, lets save this scene as

    Scenery.lws, just in case. With the Lightsource still select, select Add -> CloneCurrent Item to duplicate it, then activate the Move Tool and move this newLightsource to the following position.

    Once youve moved it, create a keyframe for it. Next activate the Rotate Tool and rotate

    the second Lightsource using the following settings.

    Picture 141: The Second Lightsources Rotation

    And once again keyframe it once youre done. Since we cloned the first Lightsource we

    dont need to scale it down, but we are going to change some of the properties for thissecond Lightsource. Open up the Properties Panel by pressing p, then use the followingsettings.

    Picture 142: The Second Lightsource Properties

    6/32

    There were only 2 things you needed to change for the second Lightsource. The Light

    Intensity should be 70% and the Shadow Type should be set to Off. Okay, now weredone with the Camera and the Lights, so lets take care of the Box Surface. Open up theSurface Editor and select the Walls Surface there. The Surface Preview will most likely

    be a very bright white ball now, so lets change that first. Right click on the SurfacePreview window and a small menu should pop up. There should be an option there called

    Use Scene Lights, and we dont need that one right now so turn it off.

    The Surface for the Walls will not be very advanced at all, we are just going to add aprocedural texture in the diffuse channel to get some variation in the material, but firstlets change some of the basic settings. Use the following settings for the basic WallsSurface.

    Click the T for the Diffuse Channel, then use the following procedural texture.

    Picture 144: The Procedural Texture for the Diffuse Channel

    Click Use Texture when youre done, and thats it for the Walls Surface. Our simpleBox Scene is done, but lets see what it looks like when rendered.

    Open up the Render Options Panel and set the Render Display to Image Viewer

    FP, leave the rest to the default values and close down the panel. Now press F9 torender a test frame, the result should look something like picture 145.

    Okay, save all the objects now to make sure the Surface attributes stays, then save thescene as well.

    Before we add the Lantern to this scene we are going to edit it a bit in the Modeler, so

    start up the Modeler now and load in the Lantern Object. Open up the Surface Editor andselect the Metal Surface, for now we are going to give it a basic grey surface, so use thefollowing basic settings.

    Picture 146: The Metal surface for now

    Once youre done, close down the Surface Editor. Switch to Layer 9 and also switch toPolygon Mode. Later on in Layout we are going to make the main steel wire (the one thatis connected to the handles) rotate a bit, but to do this we need to put it in its own Layer.

    In the Bottom Right Viewport, click somewhere on this steel wire to select a few of its

    polygons, like in picture 147.

    Picture 147: A few polygons selected on the main steel wire

    We want to select all the connected polygons to this steel wire, and theres a tool for this

    purpose. Switch to the Display Tab and click on the Sel Connect button which you willfind in the Tools list to the left, like in picture 148.

    Picture 148: Click the Sel Connect button

    This should select all the polygons of this steel wire, so press x now to cut them out of

    Layer 9, then switch to Layer 10 and paste it in there. Thats it, press s now to save the

    changes, then close down Modeler and switch back to Layout.

    Load the Lantern into this scene now, once done it should look something like picture

    149.

    Picture 149: The Lantern added to the scene

    First of all we are going to group all the Layers of this Lantern together, so that we canrotate all the parts simultaneously yet move them all at the same time. Select Add ->Objects -> Add Null and name this null Lantern_Null. Open up the Scene Editorand select all the Lantern Layers like in picture 150.

    Picture 150: The Scene editor; select all the Lantern Layers

    12/32

    Once youve selected all the Layers, simply click and hold down your mouse button on

    one of them, then drag them over the Lantern_Null object in the list to parent themto it. Picture 151 shows my Lantern Layers after they were parented.

    Picture 151: The parented Lantern Layers

    The Lantern_Null should now be on top of all the Lantern Layers, and you should seea small white arrow in the beginning of the Lantern_Null object in the list. This whitearrow indicates that objects are parented to it. If you click the white arrow all the LanternLayers should disappear, or hide within the Lantern_Null. This is it for the Scene

    Editor; you can close it down now. Okay, lets rotate that steel wire a bit, so that it restsdownwards sort of. Make Layer 10 as Selected Item now, then select Pivot -> MovePivot Point Tool in the Tools list to the left of Layout. We want this steel wire to rotatearound where it is connected on the handles of the Lantern. Change the View of theLayout to Back and fit the Lantern in the Viewport using the Zoom and Pan Tools, sothat it looks something like picture 152.

    So move the pivot point upwards now, and to make things a bit easier you can zoom in

    on the section where the steel wire connects to the handles. Picture 153 shows a close upof my Pivot Point after I moved it.

    Picture 153: Pivot Point Moved

    Okay, keep Layer 10 as selected Item and activate the Rotate Tool, then use thefollowing settings for the rotation.

    Create a keyframe after youve rotated it.

    Open up the Render Options Panel and turn on Ray Trace Shadows, then make a test

    render by pressing F9, it should look something like picture 155.

    Picture 155: A test render at this point

    Now lets rotate the whole Lantern a bit so that we see it more in-front sort of. Select the

    Lantern_Null as the Selected Item, then activate the Rotate Tool and use thefollowing settings.

    Picture 156: The Rotation for the Lantern_Null

    Create a keyframe after youve rotated it.

    Okay, were done with the basic scene for our Lantern, so select Save All Objects now

    from the menu, and also save the scene file.
