Concave quads?

[thondal]

didn't quite understand your problem but i'm doing that tutorial too;)

first remember that when you are supposed to make faces in the corner, you mus select all three vertexces and then press f, then again, then just select the three in a row, and subdivide them, and then select all 4 of them and alt+j (triangles to quads) and then when it's doesn't allways work, but if you select all four of them and then select another random vertex and then do the triangles to quads, or ctrl+f if it doesnt work.....

not sure that helped u much, but i tried at least.....

from one noob to another;):P

Thanks, but the problem I'm having is the next step - when you scale or move the middle vertexes to make the eyes round. As you can see in the picture, the triangulation of the faces is making it impossible to make the quads concave. When I move the middle vertex past the midpoint of the quad, it makes a sort of phantom edge.

oh that one... eh... have you remembered to turn on the catmull clark thingy? its under subsurf and two, and don't apply... don't know why, but then u just screw it up for some reason... but anyhow... select all the vertexces no, not all but the four that are supposed to be scaled and "rounded" and then scale them with s... nevermind the eh... don't remember what u called it cuz i don't really know that word (:P) but that will fix itself when u get a bit further.... i think... did that with me anyhow... and if the mesh looks really weird when u turn on smooth... just move the light and render it for a test... my eyes looked really weird when i smoothet the mesh, but i looked in the render image (through cameras eyes) it was all okey...

good luck, i'm doing the body now, but i have a test tomorrow so i have to read that... good luck anyhow...

hope i answered u somehow correctly this time;)

yoou can make them triangles by selecting the quad and pressing ctrl-t. then with ctrl-e (edit->edge->rotate edge cw/ccw) you can rotate the edge to make the edge flow the right way. You can try to make it a quad again afterwards with alt-j. if this changes the edges again, just leave them as triangles

[Arvetis]

Freakydude - is that really the only way to retriangulate? It's beginning to look like it might be better for me to just wait until I have access to Max again. :(

Switch to face selection mode and select your funky quads, Ctrl T to convert them to tris. Ctrl E has options for turning edges CW or CCW...

[FreakyDude]

Not to sound like a doublepost, but turning edges in max, both emesh and eploy, are almost the same. don't get so confused, try it first.
if you think it is too much of a hassle to turn them, you could just select the quad, delete it, select 3 vertex that would form a quad with edges aligned the right way, and hit f to make a face. it's not slower or faster in max, just a little difference. The real trouble here is just flipping a switch in your head to try it and don't instantly call it a bleh!! method.
Trust me, I'm an ex max junkie.

I don't think that's really what I'm doing - deleting the face and re-making it that way just makes a new bent-over face, not a concave one. Believe me, I tried that before posting. Also, I really don't want to turn this into yet another "my app is better than yours" flamewar, but max does have a "retriangulate" button. I'm really looking for the Blender equivalent of that.

Edit: Also, alt-J never has worked for me. I select both of the triangles, hit alt-J (or select "make quads" from the edit menu) and nothing happens.

I know max has a "retriangulate" button, and I don't think blender has it.
But you can get the exact same result by either turning edges with rotating them or deleting quads/tris and recreating them with f. instead of one quad, make two tris, where you have two tris who look and behave as one concave quad. If you can't make the edges flow right (yes that can happen and i think it is a bug) just make two tris. So what if tris are sloppier than quads. it's minor and you may not or will probably not notice anyway.

The way i see it: blender is more limited than max. it simply is, but you can get the same results using a little more creativity and imagination. I got (still am) spoiled by a lot of the great tools in max cutting/welding/beveling/chamfering interactively etc. Whereas blender has a number of tools i at this point still find utterly useless (rip tool for instance). but with a little creativity you can make this app work for you.

blaah, that came out wrong. i just don't know a lot of the tools in blender yet, but i can use the ones i like in a similar way i used most polytools in max. it's basically just rip that i find really useless at this point. max has tons and tons of "added fat" modifiers that get you a result that can be done in a dozen other ways if you will.
Bwaah I'm very tired, i don't want a flamewar. I like both apps, thing is blender is free and can pack a punch... goodnight

ohkey..... may sound stupid but was is concave and what does it mean? :P sorry, but my english hasn't been very good lately...

Concave is how an object curves, and which side you are looking at (inside or outside).

Take a glass. If you look at a curve inside the glass, it will be concave (moving away from you). If you look the curve outside the glass, it is convex (moving towards you).


Hope this helps.
