    I’ve downloaded a free light bulb from turbo squid. I’ve applied the textures, my problem is the light bulb isn’t exactly ’round’ There are visible flattened areas all around the bulb. I’ve done a little searching and tried a few things (subdividing to increase the polygon count, messed a little with the phong tag) but nothing makes it smooth and round.
    Ideas?

    Hi there,

    Firstly lets have a look at wether you have a phone shader on the object. A phong shader will blend the join between two polygons as long as they are below a specific angle.

    In this case select your bulb from the object window. and see if there are two little orange spheres to the right of it. if you can see this there is a phong shader attached and we will look at other options.

    OK so we have a phong shader but its not enough, we need to try something more dramatic. from the top toolbar you can see a green cube suspended in a wireframe cube, left click and hold on this icon, then select hypernurbs from the menu. Hypernurbs are good for making organic and smooth objects. Now we have a hypernurbs in our object veiwer, select your bulb and drag in onto the hypernurbs icon. This will place the bulb within the Hypernurbs. You should now see that the bulb is made from more lines, its subdivisions have increased!!. if you adjust the settings you can see that you can adjust the ammount of polygons the bulb is made from, and thus the smoothness.

    apologies for the long answer. pm me if you need any further help.

    Good luck!!

    You may have to go into points mode, select all the points on that mesh that’s causing you the problem, go to FUNCTIONS, then OPTIMIZE. Make sure the tolerance is set to .01, then hit OK.

    I bring in a lot of models from downloadable sources and many of them, the polys are exploded and you need to bring them back together again – this is what OPTIMIZE will do in this case.

    Next, you can drop that part of the bulb into a Hypernurbs object and that will take care of a wonderfully smooth surface for you.

    Hope this helps,
    Murf

    Hypernurbs to the rescue! Thanks a lot, that worked great. It already had a phong tag on it btw.
