Selecting faces in X,Y or Z

[Levitateme]

turn on backface culling. i just go to display, custom polygon display then i turn it on there. last time i tried it using the view, backface it didnt work. i could still select, whati couldnt see. so try both.

Yeah but backface culling will still select stuff I dont want to select. Im basically trying to select faces of a building for planar mapping. and to save time I was wondering if there is a method of selecting faces per axis.

So basically I want to select the polys that face in the x axis and nothing else - not the polys facing Y or Z, then I'll have all the X facing polys ready for a planar projecection. I'd then repeat this with those facing in Y and Z...

oh, sorry i dont know that would be neat though.

[Elliotjnewman]

Does anyone know if there is a mel script that can do this? I have tried the paint selection tool in the orthographic view but this doesnt really work. Surely there is way to do this, so that only the faces that are pointing towards the camera get selected???

Help!!!

elliot i was thinking, if your in front view, you have backface culling on you select, that is only gonig to select the faces visible in the viewport anyway. so that would be doing the exact thing you need right?

i just tried real quick in the side view, it worked preferct

[Elliotjnewman]

Yeah that kind of worked but it still isnt what I want. All I need is a way of selecting faces quickly for applying planar maps. the backface culling will still select poly I dont want.

It seems this is impossible, or at least nobody has ever needed to this apart from me!

you can select using the front view...deselect using the top view....

Map the entire object with 1 planar map....then

I would recommend doing planar maps based on the camera view....and then select /deselect the faces via the Texture editor....change views and continue mapping. As you go along you end up isolating the faces...and because you can select/deselect directly in the Texture editor things progess pretty quickly.

You can even re -map a couple times this way once you have the things isolated ....its actually pretty fast. Also check on Highend for anything that sounds like Box mapping or 6 sided planare projections or whatever.

I know very rare people using this.

Your model is poly isn't.

Go to Edit Polygons>Selections>Selection Constraint

Switch on Constraint to Next Selection, open geometry tab, open Orientation tab, switch on Direction, set Min and Max to 0,
then set Vx, Vy or Vz to 1 according to your selection axis.

All faces on YZ plane - Vx = 1, Vy = 0, Vz = 0
All faces on XZ plane - Vx = 0, Vy = 1, Vz = 0

Hope this help,

forgot about the selection constraints....kewl

[Elliotjnewman]

Yeah I did look at the selection constraints before, but now I know where to look it has helped. This method is exactly what I wanted, selection constraints seem to be ideal for selecting faces for planar mapping!!

Thanks, Ell.

sorrry elliot. i would post on the mel forum here, and go to highend3d were i think the mel forum is much more focused on. ask someone tehre cause on highend everytime i look the weirdest requests seem to get replies. just tell them yuppies what you want.

[Elliotjnewman]

The selection constraint has worked for me so far just fine so I shouldnt have to use a mel.
