Hi Everyone. I have just recently switched from 3dsmax to lightwave. I feel that lightwave is very powerfull, and im sure i will stay here for a long time. I kinda feel at home(although i seem to bang my head against the wall all the time still).

And now a new problem has occured to me. I know its probaply very simple, but im almost paralyzed because of this.

When i extrude, lets say a face on a box, it comes out with flipped normals!
so i have to manually flip em back... This is such a creative killer having to work around this. If anyone knows what i can do, or what i have done, please tell me!

You can flip them back by hitting the f key, but the reason that you have extruded "inside out" is that you need to extrude in the opposite direction to the normal.

you can also use smooth shift to extrude polys (shortcut = shift f or F). Thats a better tool for extruding things. Polys won't get flipped and you won't get polys inside your model.

good luck

In the case of extruding a face from a box, which gives the effect you describe would it be perhaps better to use bevel instead with no offset. [Or indeed smooth shift]

Coming from max to lightwave is a litlle confusing for me. So thank you very much! I never expected such a quick reply.

Also, you may use Extender Plus. Just select the points that you want to make new geometry with, hit the e key, and then, move (t), stretch (h), or how ever else you want to manipulate the new geometry.

BTW--When you first hit e, it seems as though nothing has happened. That's why you must move the points, after you use Extender Plus.

A cool thing about Extender Plus is that you invoke it while you are in Move mode unlike many other tools. I never knew this until Proton had mentioned it in one of his recent tutorial videos. :thumbsup:

Alternatively you can use our not so long ago released EasyMesh http://easymesh.trueart.pl
What is tool doing depends on where you left/right click, not what is selection or setting - context sensitive action..

Select the polygon and look at the normal of that polygon, the dotted line, That normal will tell you what direction the poly will face when extruding.
If you want to have the polys face inwards then extrude same direction as the normal points. If you want the polys to face outwards then extrude the opposite of the way the normal points.
If you forget, don't sweat it as press the f key will flip them for you.
