Eric2575 Posted March 12, 2005 Share Posted March 12, 2005 I started out with a single spline with several CP's connected to form a rudder shape. After selecting that closed loop, I extruded twice. Once done with extrusion, I wanted to stitch the sides together to create the side faces. On my first stitch, I noticed the distortion you see in the jpeg. Normally I see that with overlapping splines, but how can that be on such a simple shape? Two extrusions is all. Also, when I select a CP and pull it away, there is no other one hiding behind it - if that makes any sense. Any ideas? Quote Link to comment Share on other sites More sharing options...
KenH Posted March 12, 2005 Share Posted March 12, 2005 Those curved splines should continue on and end on the flat part. Right now they seem to stop dead. Quote Link to comment Share on other sites More sharing options...
Vash Posted March 12, 2005 Share Posted March 12, 2005 Well for starters I'd say that there are too many splines in the area I pointed out. One other thing. It may not show if you have two splines running through one spline to another. I'm saying you should try and break the area around the distorted area. Break the splines and see what happens. Two patches rendering in one spot causes distortion like that. Quote Link to comment Share on other sites More sharing options...
heyvern Posted March 12, 2005 Share Posted March 12, 2005 Couple of things to check/try.. Do a render to make sure this anomaly is visible. Also, whenever I do this type of modeling... I will peak all the splines in those areas and use bias to create the curved "bevel" on the edges. When you have the "curved" splines in that situation wierd things happen... specifically a single long spline like that across a patch. I bet if you added a couple of extra splines... hey! You already have 'em! As Ken mentioned this will go away if you continue those dead end splines all the way across to the other side. It will of course create 3 point patches but they won't look too bad. Vernon "!" Zehr Quote Link to comment Share on other sites More sharing options...
Eric2575 Posted March 12, 2005 Author Share Posted March 12, 2005 Here is my final attempt for this project. Not perfect, but very doable. Is that a word? This is the rudder for the Nautilus. Quote Link to comment Share on other sites More sharing options...
R Reynolds Posted March 12, 2005 Share Posted March 12, 2005 You seem to be dissatisfied with the slight creasing around the corner. You might try increasing the magnitude of the "circumferential" splines that define that corner. I usually use a mag = 167 but you may be happy with a different value.

Eric2575 Posted March 13, 2005 Author Share Posted March 13, 2005 I played around with bias and magnitude and got even better results. Getting a good nights sleep can do wonders. Thanks for the tip Rodger. Quote Link to comment Share on other sites More sharing options...
