230Airbrush and Morph MapsLightWave 10 - ModelerTo use the Airbrush with a Morph Map, select the morph youwant to paint on from the Vmap Bar at the bottom of the screen.Select the morph you want to paint from in the Vertex Map menuin the Airbrush Numeric panel.ShapeChoose the percentage of the Shape that you want to apply fromthe Shape text field. You can change the current morph half wayto another one, or change parts all the way, or just take 10% offthe top. It’s very flexible.You can also paint a morph onto the Base; but if you do, it willchange all the relative morphs in your object. You are given awarning if you attempt it.Clear Map (default keyboard shortcut _)To clear a Vertex Map, select the map you want to clear from theVmap Bar, and click on the command. All values will be cleared,no matter which kind of map you chose. (Weight, Texture (UV),Endomorphs, Color Vertex Maps, or Selection Sets.)To clear an entire map, make sure no points or polys are selectedbefore you click.This differs from the Delete Map command because it leavesthe map. Only the information contained in the map is deleted,so you can immediately begin to put more information in, withouthaving to create another map. If you don’t add information, themap will be deleted when you leave it. (Empty maps don’t persistin LightWave.)To partially clear a map, select the points or polys that you wouldlike to clear. Click the button, and the values for those points andpolys will be gone.This is extremely useful, as it allows you to correct your maps ona point-by-point basis.Airbrush and Color MapsTo use the Airbrush tool with a Color Map, choose the map youwant to color from the drop down list. Make sure that it’s beingused on a surface, and is visible. (Check the Advanced Tab ofthe Surface Editor for use.) The Airbrush will paint on maps thatare not showing, so be careful. If you don’t see any effect, don’tassume that your settings are too weak.NOTE: Don’t use this function to clear a copy of amap to make symmetrical morphs, etc. Instead,just select the part you want to keep when youcopy the map in the first place.Choose a color from the normal Color Requester. Be aware,though, that LightWave will apply the color over the base color ofyour object using the Multiply Blending Mode. If you are familiarwith Photoshop, it’s very similar. Adding color will always makethe base color darker, never lighter. (If that’s a problem, simplystart with a white base color, of course.) The colors you paint onthe map itself will replace whatever colors are there, so it’s easyto lighten them.AlphaIf you are using an Alpha Channel in your map, (enabled whenyou created it,) then you can also adjust the Alpha with theAirbrush. Do this by either changing the number in the Alphatext field, or by holding down the Ctrl key as you paint. You canincrease the Alpha by using the Alpha text field; but it will alsoadd color. (Which is just as well, really, since uncolored pointswith 100% Alpha are black.)
