View Full Version : adding edges to objects...

02 February 2003, 10:06 AM
ok, having some probs with the LW edge line facility, for some reason it's fine on the nearest demo pod, but on the two in the background it keeps marking the contour lines (see pic), i've tried all the various edge settings (unshared, sharp etc) but no joy, and whenever i try the Unreal toon tracer it crashes LW...anybod help?

p.s. don't knock the modelling, it's a sketch scheme, going to pitch on friday so i'm rushed off my feet :D

on the textures used on the back areas, did you set the texture to a different smoothing than the front one? Also check to see that you don't have any 2-point poly's or duplicate poly's where you're getting the unwanted lines. Hope this helps!

02 February 2003, 12:22 PM
textures are the same, is there a quick way of checking for 2-point and duplicate polys? Cheers for the help! :)

I would set the view to wireframe, then select what appears to be a single poly. look at the bottom left of the modeler window and it will tell you how many poly's you have selected. If it looks like you've only selected one and the display says you've got two then you can merge poly's to get rid of it. to find 2-point poly's just hit Ctrl-H to enter poly selection mode, make sure you don't have any poly's selected and hit 'w'. Then look under the area for 1 or two point poly's. hit the plus sign next to those to select them and then hit delete. Cheers!

ta for that, i'll give it a go! :)

Try increasing the 'Sub Patch Resolution' in the object Properties panel. Just a guess but worth a go. It looks like I can see Polys which may indicate a problem with the resolution of the mesh.

ok, i have a 'subpatch' level setting and a metaball 'resolution' level setting...which do i tweak? :)

02 February 2003, 04:11 PM
It's called 'Render Subpatch level'

02 February 2003, 04:33 PM
thanks, but no joy with that one :)

I see circles as being the main theme to a lot of your exposition designs... Don't forget the other shapes!

So, any luck yet with what I suggested? I know you probably can't do this, but if you want me to take a look at the scene file I may be able to help you fix the edge problem. Just let me know.

i'm not the only designer here, but i'm the only LW visualiser! :) i.e. they're not all my designs!! that pod i've shown here is a system we may buy in, so it's not any of our designs, ellipses are quite big at the moment, anyway...

personally, i'm a Mies Van Der Rohe man myself ;)

i don't have a prob sending you the file but i'm a tad snowed under at the moment...

Well, I'm on Eastern US standard time (GMT -5) and plan on being in front of the computer for the next 3 hours. If you get a chance to email me the files, I will definately try to help (It seems I'm doing lots of Not-for-profit work lately anyway). Don't work too late!

Maybe you need to physically increas the resolution of the mesh??

02 February 2003, 01:36 AM
have you tried merging points (m) and unifying polygons?

02 February 2003, 02:59 AM
yes, hit "m" and merge points, then hit Shift+i

02 February 2003, 04:31 AM
So theres no way to render shadows when rrendering like this?

02 February 2003, 09:44 AM
hmm...merging points makes it worse...thing i don't understand is the canopy's in the background are duplicates of the one in the foreground... :shrug:

02 February 2003, 11:50 AM
ok did you unite polygons by hitting shift+i after merging points?

02 February 2003, 11:51 AM
yeah, the front face polys i doing something blindingly, stupidly, wrong? :D

02 February 2003, 11:57 AM
woah! completely dissappeared? try flipping them (hope I'm not insulting you!)

02 February 2003, 11:59 AM
if i flip them then the back face disappears.... nope, not insulting... :)

02 February 2003, 12:03 PM
Ok try this... go to the Detail tab and hit "align polys". Hopefully that will work. Either that or make the surface double sided

02 February 2003, 12:08 PM
nope, not worked either....go on, i'll ask a silly do i make something double sided? up to now i've just been copying the polys and flipping them, never had a prob up till now...

02 February 2003, 12:14 PM
AHA!!!!! :bounce: That's the problem right there! I've found copying and flipping causes nothing but problems. To make a surface double sided just go into the surface editor and check "double sided" down the bottom :D. No more copying and flipping now, you hear? :shame: Besides, if you have a cylinder and all the polys are facing "out" then you shouldn't need to have them double sided because you can't seed inside it anyway.

02 February 2003, 12:25 PM
HUZZAH!! works perfectly! I've learnt my lesson! all is right in the world once more!!! :buttrock: :airguitar :buttrock:

cheers for that!! :beer:

02 February 2003, 12:30 PM
so the problem DID end up being caused by extra poly's... just as I suggested... too bad I didn't know you had no idea how to set the surface to double sided...

02 February 2003, 12:32 PM
hey, as i said, i've never had a problem with it before so didn't think 'that' would cause the problem, it's only with doing this sketch scheme that it's come to light...
