maddle Posted October 11, 2009 Share Posted October 11, 2009 Hello A:Msters, Here is a my question, how canI avoid creases i have on my model, the flow seems ok but i still have some pinches.Does thes disappear after texturing, or do i have to adjust bias, or there is a function to smooth the splines ! any helps, tutos, advicse are welcome ! thank you.

largento Posted October 11, 2009 Share Posted October 11, 2009 I would take that spline that hooks in the space between eye and nose and run it across the nose. Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted October 11, 2009 Hash Fellow Share Posted October 11, 2009 First, use as few splines a possible. Generally, you try to mark the peaks and valleys of a shape with splines and have few in between. You're not doing too bad but I think that nose has more than it needs. Second, the little bumps you see where one patch meets another can be solved with bias adjustment http://www.hash.com/forums/index.php?s=&am...ost&p=43673 I find it easier to click and slide on the gamma bias property for a CP to adjust it rather than to use the bias handles. It usually only needs to change a few degrees. Quote Link to comment Share on other sites More sharing options...
*A:M User* Shelton Posted October 11, 2009 *A:M User* Share Posted October 11, 2009 You have got a really good start. I would run the splines across the nose to remove the deep angle of the 5 point patch beside the nose. Also pull the second spline under eye down. The closer each spline gets to each other the more like you will have a crease. Really good start! Steve Quote Link to comment Share on other sites More sharing options...
Eric2575 Posted October 11, 2009 Share Posted October 11, 2009 I would venture to guess that you have the bias manipulator button turned on during modeling? You might not want to do that at first since you can inadvertently tweak biases while modeling without really being aware of it. This can happen when you are in wireframe/shaded mode, you select a cp, nudge it, but see nothing happening. So you go on and don't worry about it. What could have happened is that you actually grabbed a bias handle, maybe on the other side of the mesh, and tweaked the heck out of it with that little nudge. You don't see the damage until you turn the model or inspect it as you are doing now. Just a thought. Quote Link to comment Share on other sites More sharing options...

Hash Fellow robcat2075 Posted October 12, 2009 Hash Fellow Share Posted October 12, 2009 Wait until you have your mesh done before you start worrying about bumps. Quote Link to comment Share on other sites More sharing options...
Xtaz Posted October 12, 2009 Share Posted October 12, 2009 there is a material called PORCELAIN that smooth splines .... you should try it... but the best way to smooth a model is to mantain an efficient splinage and a low count of the patches Quote Link to comment Share on other sites More sharing options...
maddle Posted October 14, 2009 Author Share Posted October 14, 2009 Does any guys around can give me a hand and explain or correct my mesh to have less creases, i m close to give it up ..no i won' t !! i really love to model with A:M but the journey will be long... here is my mesh and the background from lightwave. patch_apple14.mdl ps:Porcelain give me awfull results.

Eric2575 Posted October 14, 2009 Share Posted October 14, 2009 Maddle: You are very good with spline layout and keeping it simple - do not give up modeling. There were several discontinuous splines and other odds and ends. I only fiddled with the left side of your really nice looking model so you can compare with the unchanged right side. If you want to have both sides the same, just do a copy/flip/attach. I'll check back to see if you have any questions about what I did. Sorry, misspelled the mdl file. As Xtaz mentioned, porcelain will help out, but you should have your model really smooth to get the best results. creaes.mdl Quote Link to comment Share on other sites More sharing options...

Thank you Monsieur Eric to encouraging me ! , ok i see ...no shame to use the kung fu hook technique !!!around nostril for example ! Ho and by the way i don t know how to make a plugin shortkey !! the plugins do not appear anymore in tools/customize/keyboard ! or may be it s not the right place for these settings.

Eric i can t select the right side of the model to delete it ? it seems to be "frozen" but i can t access the lock cp s which stay gray ?

maddle Posted October 14, 2009 Author Share Posted October 14, 2009 ok me again first why sometime i ve two handles and some time only one ? is it because the patche is still not created yet ? and what Steve ? is the best approach here 5 ponts patches ,hooks ? patch_applev15.mdl Quote Link to comment Share on other sites More sharing options...
steve392 Posted October 14, 2009 Share Posted October 14, 2009 Heres what I did ,just a quick try .There is probably a better way but this should give you some alternative.You need to think for a time to get the best results Quote Link to comment Share on other sites More sharing options...
steve392 Posted October 14, 2009 Share Posted October 14, 2009 Maddle I would look at other models to see how others do it .There are plenty of good models to look at .Everyone find's there own way ,there is no right way ,just as long as it work's for you Quote Link to comment Share on other sites More sharing options...
Eric2575 Posted October 14, 2009 Share Posted October 14, 2009 There are two reasons why you sometimes get only one bias handle - 1. You have a discontinuous spline (two splines meet but do not join as one) 2. You have a peaked spline. A quick check would be to select one of these cps and hit "O". If it's a peaked spline, then it will smooth out. If it does nothing, then you have two splines meeting there. To make a discontinuous spline merge into a continuous spline, select one of the cps by clicking on the spline right next to it, hold down "shift" and at the same time hit "k". This action will release one spline from the other. Without moving anything, hit the same spot on the spline as you did before, only this time hold down the left mouse button while at the same time clicking the right mouse button once. This will join the two splines and make them one. Kinda long winded, but it's hard to put into words. Quote Link to comment Share on other sites More sharing options...
