betty Posted July 12, 2002 Share Posted July 12, 2002 frustration once again over a simple thing so i'm turning to the trusty odforce forum. I've this poly half head and i duplicate it, scale -1 to the get the other side. I use the reverseSOP to get the normals right. I want to merge the two sides into one. Now i use the fuseSOP to consolidate the points down the middle of the object. When i append a subdivideSOP i have this edge going around the loop of points right down the middle which i used the fuseSOP on. Can someone let me know what i'm doing wrong? Thanks Betty Quote Link to comment Share on other sites More sharing options...
stevenong Posted July 12, 2002 Share Posted July 12, 2002 The problem you have is due to reversed Normals. Go to the SOP before the Fuse SOP & turn on Prim Normals in the Viewport. Notice how the Normals of each half are facing away? This is due to the Reverse SOP performing the operation on both halves. To solve this, in the Duplicate SOP, turn on "Create Output Groups". Now in the Reverse SOP, click on the Right Arrow of the Source Group parameter to select copyGroup1. Voila! The seam is gone! Quote Link to comment Share on other sites More sharing options...
betty Posted July 12, 2002 Author Share Posted July 12, 2002 Steven That's what i did, but i did it in the viewport and had my duplicate geometry selected when choosing the reverseSOP. I also checked my normals - all is fine that area. I just did it again like you explained in the network editor but that seam is still there???

stevenong Posted July 12, 2002 Share Posted July 12, 2002 Did you move the duplicate yourself? Or did you set X scale to -1 & then turn off "Pivot about Group Centroid"? Quote Link to comment Share on other sites More sharing options...
betty Posted July 12, 2002 Author Share Posted July 12, 2002 I turned off "Pivot about Group Centroid" and then scaled X to -1 in the OP Parameters. Quote Link to comment Share on other sites More sharing options...
stevenong Posted July 12, 2002 Share Posted July 12, 2002 You wanna try using a Dissolve SOP to remove that edge loop? Quote Link to comment Share on other sites More sharing options...
betty Posted July 12, 2002 Author Share Posted July 12, 2002 Yeah i know, but i thought i'm doing something wrong - that's why i have the loop left over. I'll try dissolving it. Quote Link to comment Share on other sites More sharing options...
stevenong Posted July 12, 2002 Share Posted July 12, 2002 I have a half poly head from somewhere & after fusing, I have a loop there but it's smooth. Maybe you can turn up the fusing threshold. Else, before you duplicate, use an Edit SOP to flatten the edges onto the Construction plane. Right-click on the Construction plane button & select "Center c-plane around World X-Axis" to align it. Please let us know how it goes. Quote Link to comment Share on other sites More sharing options...
DaJuice Posted July 12, 2002 Share Posted July 12, 2002 Hey, and if all that doesn't work, try using using the Facet SOP to consolidate points instead of Fuse. I didn't even know there was a Fuse SOP. Quote Link to comment Share on other sites More sharing options...
betty Posted July 12, 2002 Author Share Posted July 12, 2002 Hey guys, I've done all that, *weird thing with the construction plane, i actually flattened two points to the plane which i aligned to the World X-Axis. but it didn't work, the ponts moved and when i checked in orthograhic mode they looked like they flattened to the plane but when i fused the loop they didn't come together????? *i've also tried the facetSOP, bu i think the fuseSOP pretty much does what the facet would do under these conditions. ?????? i'll keep trying in the meantime, i'll put this head up as it is Betty btw, in Vex shaded mode you don't see the loop in the viewport but it renders. and the other thing is it actually doesn't go all the way around the head...?..i've played with the parameters. i've spent too much time on this little thing - i'll get the image up and figure it out latter.

Marc Posted July 12, 2002 Share Posted July 12, 2002 Hi Betty couple'a things. Turn on point number display to see if there are still duplicate point numbers at the place where you're getting the seam. Also, and this might be hard to spot. Turn on primitive numbers (turn of point numbers first ) and make sure there are no extra primitives lying around the seam area. I've had that before where I've been modeling and I'll leave a degenerate polygon lying about and won't see it. If you do have any extra ones then use a blast SOP and just type the number into the group field. Also, you should all know that this kinda thing (the duplicating->revers->fuse thing) is gone with 5.5. In 5.5 there is a mirror SOP which does it all for you. Its pretty neat.

betty Posted July 12, 2002 Author Share Posted July 12, 2002 Hi Marc, Thanks for that, i'll give it a go when i get back to work ( just started the weekend! ), i'll let you know how it turns out. re: "Turn on point number display to see if there are still duplicate point numbers at the place where you're getting the seam. " *I did this and saw no duplicate points. re:Also, and this might be hard to spot. Turn on primitive numbers (turn of point numbers first ) and make sure there are no extra primitives lying around the seam area. I've had that before where I've been modeling and I'll leave a degenerate polygon lying about and won't see it. *I'll try this, but i recall i had an option in the fuseSOP checked regarding degenerate polygons???....mmmm...i'll check it in a couple of days. Good to hear that the mirrorSOP is on the way, i'm a huge fan of the mirrorOP - the more tbe better. Betty Quote Link to comment Share on other sites More sharing options...
TheUsualAlex Posted July 12, 2002 Share Posted July 12, 2002 Hiya, This is probably a repetition and everyone probably knows about it. If your seam is still there after you tried checking on the centroid stuff and that there are no accidental duplicates, please make sure that no one vertice is sticking out. what I generally did is go to the model's front view and move the point by hand so that it's close enough where it doesn't matter. After that is done, pop in a group SOP and use a bounding box to bound all the points on the outer edge only. Afterward in Fuse SOP, you can specify the group to be fused. I think this should be easier as well. Cheers, Alex Quote Link to comment Share on other sites More sharing options...
