Granular lasso selection of objects/entities/props on decompiled maps

[glass osprey]

Hello! I'm trying to edit some valve maps for practice and am having issues selecting particular areas of the map. Any help is greatly appreciated.

When I selected this prop_static door(appears to be in some node format) for example it selects a whole wack more of map items, like this mirage cat door that extends over to "ticket booth" on CT/A-site area.

My main problem extends with wanting to "slice" the map around with precision but when I think I'm lassoing one particular section of the map, it's grabbing unexpected groups in other places (as shown in the top-down view screenshot

Again, any help in understanding and pointing me in the right direction would be very ground breaking for me and I would be super appreciative! 🙂

Thank you so much!! :):)

Edit: Just to add to this, I've tried deleting selection sets, converting to editable meshes on props, and looked for accessing many features that are greyed out.

this is just the nature of how worldnodes work

they are separated into different materials

so sometimes if u select a door it will select something somewhere else thats using the same texture

you could convert these to mesh though

Hey @leaden root

Thanks for the reply!

So I did try this earlier, and when I left-click the door on cat, and select convert to editable mesh, I still get selections of other things across the map.

If I select faces-mode, it seems I can't really easily lasso, or shift+mouse1 a bunch of things easily and hit DEL and have the items I think I'm selecting and deleting actually delete.

Any tips based off that info?

[leaden root]

Yeah you can try selecting connected faces

Like

well

assuming you're on US layout keyboard

select one face from the door on cat

then while holding shift

just spam 2 and 3 at the top of ur kb

til all the connected faces are selected

then u can do alt+n to separate it

maybe theres a smarter way to select connected faces but thats how i do it

if u arent on US layout keyboard u can just press edge mode and face mode (and repeat) at the top of the screen instead of pressing 2 and 3 on ur keyboard

So this works nice

There appears to be a few many other things grouped together from the world nodes(?) of the original "slice" of the map I had in mind

so I would have to go around and root out each stray object on the other side of the map and do the mouse1+shift(hold)+1&2&1&2& until I separate all of them?

[leaden root]

that would be how i do it but.. theres probably a better way

[glass osprey]

Well life has it's many starting points to breakthroughs, and this is solid information for me to start on. from overhead I can see for the most part the stray items it just gets nerve-racking when i do long compiles and make discoveries of walls and things missing

[leaden root]

Yeah i bet

What are you exactly tryna do anyway?

out of curiosity

[glass osprey]

End goal is a little bit of a secret but in a vague sense, I want to lasso/slice sectors of maps apart and be able to move them freely

[leaden root]

danger zone map that integrates official maps

[glass osprey]

(and not have to worry about deleting the wrong things, or moving things into areas where I miss them

[leaden root]

yeah fair

[glass osprey]

Last night my breakthrough was finding enable lasso select through and enable lasso select partial intersection which got me really close to "slicing" things.

It's just finding a way to separate these oddly grouped objects

[leaden root]

well if they are some considerable gap between each other

you could just use shift+x (slice tool)

if you do it while in mesh mode it wont create any extra faces or anything either

you can make one cut, press space then keep making more. learning that saved me a lot of time lol

i personally find using the slice tool is best on the 2d views fyi it can be pretty finnicky on 3d view

[glass osprey]

one sec lol

slice from top view appears to leave some things behind

[leaden root]

oh yeah it will only slice meshes

not props

so u would have to convert those worldnodes all to meshes. not sure how viable that is

[glass osprey]

I see

well

hmm

fuck

[leaden root]

i was assuming it was more for smaller chunks of the map not for half of the entire thing lol

[glass osprey]

it helps a little

at least it exposes props with the geometry around them completely gone

but god I hate how world nodes are all grouped there

[leaden root]

😄

what map is this ? mirage?

[glass osprey]

yep

[leaden root]

well..

one other thing u could try

[glass osprey]

and I just evaporated A side of the map

[leaden root]

port the csgo version to cs2, then delete the materials it comes with (since there are already mirage materials in the game, no need to port them)

[glass osprey]

I would like to use similar methods on other maps as well where there's more verticality

[leaden root]

then that would be a lot more easy to work with

[glass osprey]

vertigo-new for example

[leaden root]

ah right

vertigo wouldnt be too hard still tbf

[glass osprey]

🥲

[leaden root]

but something like inferno is impossible with what im suggesting yeah

[glass osprey]

yeah I don't think csgo port approach would be easier for what I have in mind

[leaden root]

yea maybe not

[glass osprey]

I honestly was using slice tool awhile back and complete forgot about it for some reason

I think it's going to help me a lot more than I think

I can really isolate the problemed props I think, they just might blend in with the darkness of 3D view sometimes

but I think ultimately I can just lasso select and we're laughing basically 🙂

just convert them to mesh and stop my whining and get'er done I think is the approach - yes?

[leaden root]

yeah pretty much

seems like your best bet

[glass osprey]

super. thanks again @leaden root you're a boss 😎
