Modeler

270LightWave 10 - ModelerPanel, nothing you do in the UV Window will affect the geometryof your model at all, since UV space is separate from X,Y,Z space.Poly MapAdjust Polygon MapThis button will allow you to adjust your old Per-Polygon Maps,or to treat new UV Maps as if they were Poly Maps, and adjustthem.How do I use this tool?Be aware, though, that in order to do any of this successfully,you must be sure that you have unwelded all the seams on yourmodel. If you don’t, any polys that aren’t showing a point willremain “stuck” to the map in that place, and will become severelystretched. (In the picture shown, you can see that there are pointsmissing in the corners marked. There are also points missing allaround the circumference of both circles.Whenever two polysshare a point, only one will have it on the map, and it’s a problemif it’s on the edge)This image shows the use of the Flip tool; but the same principleapplies.To fix it, undo, then select the points that are being shared (Onthe model, they’ll be on the poly next to the one without its point.If you select that poly on the map, it will light up on the model too,and you’ll be able to find which points to unweld easily.)Go to Detail > Points > Unweld, and every poly will be given itsown points.When all the edge polys are showing points, go ahead andmanipulate them.Select the polygons that use the Poly Map, and click on thecommand to open a dialog, which lets you adjust them in severalways. It will also let you treat normal UV Maps as if they werePoly Maps, although it’s better to use the newer tools. To do that,select the polygons, and enter the map’s name in the Vertex Mapfield. (If you are editing real Poly Maps, leave that field blank.)This tool will not work on unselected polys.Reverse Order and Shift Order adjust the connection betweentexture points and the polygon’s vertices. Checking TransformTexture will enable the Rotation Angle, Scale U and ScaleV fields. They all allow you to perform 2D transformations ofthe UV coordinates. The power of these operations is limited incomparison to the tools available for editing VMaps.If you want to use those tools on your Poly Maps, simply usethe Unweld command (Detail > Points > Unweld). This will putpoints on all the polys, and remove Per-polygon UV Mapping.At that point, you can use all the Modify tools, as you normallywould. If your models are simple enough, you can Unweldselected points; if not, you can effectively unweld the entiremodel. Just be sure not to move anything in X,Y,Z space, andthe Merge command (M) will put it all back together again whenyou’re finished mapping.
