LP disk question,

ENODMI

So I see a lot of modelers cleaning up polydisks by eliminating the converging triangles from a center point (middle), to to making new edges that pass back and forth across the disk(left). This only saves a few polys, so i was wondering, is there another reason for doing this? Does a high amount of of polys converging on a single point (far right) cause problems in realtime rendering or something? Or is the center one ok? I kinda like having the center point for reference in lining it up with other objects.

Yeah, in realtime, if your not careful with your normal maps, you can get some lighting errors there. We call them "cat asses" its always a good idea to avoid having a vert with that many edges attached to it. It can be a real "cat-ass-trophy" he heh.. I crack my self up:)

For high poly meshes, it is primarily because when you take it into mudbox and zbrush, that centerpoint will create really bad subdividing, so if you actually try to sculpt on it you can't really do anything without it screwing up.

For low poly meshes, it is primarily to save 2 triangles, which becomes more worth it the lower poly the object is and how many time it is used on the prop. It is usually the very last step in optimization before export though, since as you mentioned the center point is very useful for snapping and aligning objects. It also creates weird loop selects if you loop select certain edges.

Thanks guys, makes sense, Im busy cleaning up all the cat ass now:)

also it helps with tri stripping. look about half way down this page http://www.ericchadwick.com/examples/provost/byf2.html

tri stripping cat asses ? :poly122:
