I say just create the background in sketch up(your own original one), put the camera how you want it and then just trace the environment, seen too many comics using 3d models for 2d characters and it looks weird too me, it's easy to spot and takes me out of it
@GalacticPotato
as someone who has practice perspective a lot, it dose get easier just not quicker XD
Seconding Idiotwithapencil. It's a good tool but only when it's used as a tool and not a crutch. Don't use filters and just slap it into your comic because it looks incredibly jarring against hand drawn characters. It's really off-putting reading comics that do this. The most I've ever used it for is to just set up some basic horizon lines, take a simple rectangle outline and build my own environment from there.
if you wanna get up your webcomic production to official webtoons speed (40 panels a week) and get a better shot of being pro, better learn sketch up or get a partner who is a background specialist with prociency in sketch up.
the pros do it, why shouldnt you?
you dont have to be good at everything.
oh yeah trace the backgrounds obviously, mixed media is still far away from being acceptable.
I agree with what Spudfuzz and WednesdayAsh said.
Sketchup allows you to use the models for your comic, as long as you don't use it for commercial use (unless you purchased a license).
Aditionally, I've made 3D models before (although I don't post them online, since it's simply not my focus), so I'd be flattered if they were used in someone's comic to be honest.
And pros use Sketchup all the time. Yuumei169, Tsulala109, Feigap95, and many more!
If you learn how to use the program, it's a skill and not a crutch.
A lot of anime artists also use 3D programs to draw backgrounds, so use any programs available to your advantage. I'm not a big fan of those who don't trace the backgrounds (they just take the model and put it in their comic) because things just feel out of place. Of course, that's just my preference and some comics can make it work better than others, such as Killing Stalking.
However, I would also recommend learning perspective, since it will also be helpful to you when you want to add extra details to your buildings and such.
Or maybe you want to slightly exaggerate some buildings proportions just to match the atmosphere or a certain scene and such. So learning both would be good. \o/
hell yea go for it. if it saves you time then do it.
ive been thinking of building my own things using sketchup but the program has changed so much over the years i remember using it back in 2016 and it was so difficult to use. maybe ill use blender next time.
I'm not really into making a 3D modeling portfolio like what you said, so definitely not 
Also I wonder if it's okay to use a free model (like the interior of a room) then tinker it a bit here and there and claim it as your own ...? And I definitely do need some models, its great that SketchUp has a lot of furnitures. Since the both of you recommended Blender, I'll make sure to learn about that, same with Maya.
You make games? thats cool 
I'm a bit of a perfectionist, so definitely it'll take time. Welp, time to go to youtube for tutorials 
Uwah, I didn't really look through the Terms of Use so thanks for reading it for me, haha. I guess I could just trace the model and make it look a little bit different then credit the creator or... just seriously learn how to use SketchUp so I don't need to use existing models.
That is so true! I've seen some comics like that and looking like it was out of place 
but its just that there are also other ones that looks like it fits just right too (webtoons like untouchable, noblesse etc.) But yeah, I'm gonna go for tracing instead just in case -.-
Yep, definitely gonna learn it. And tracing is a really good strategy 'cause I could just add things i want and it wouldn't look out of place if it was with 3D. But thats kinda sad though that mix media still isnt accepted.
i don't know what program what this artist uses but she makes really good 3D backgrounds for her COMIC253. i've seen rough sketches but never the process
Thanks for the encouragement on using SketchUp 
and ooooh fellow Killing Stalking reader, nice to meet you 
And yes, I know how to draw in perspective (learned it from school) though its not exactly my forte. I'm also into exaggerating drawings like foreshortening (but have yet to learn 3rd point perspective tho)
Really? I read this webtoon from time to time 
Can you give me a link of where you've seen her rough sketches?
she doesn't post them and she only streams when drawing characters after all the backgrounds are complete. sometimes she hides the finished bg and switches to rough.
i've been asking her but she doesn't respond. can't blame her though. the bg is an important recipe of her masterpiece xD
Yaaaas. She wouldn't want anyone stealing her precious. I'd do the same if I we're her and where are you trying to contact her? From what I know god-level artists are really hard to get to talk to 
This artist also uses Sketchup.
Their backgrounds look exactly like Sketchup's style and I see them using some models I've found before on Sketchup. It seems a lot of people hide the fact that they use a program for their BGs (like this artist) probably because they might feel uncomfortable about letting people know. Especially since when you posted this, you felt that using 3D models was "not nice", until people started commenting that using the program is a skill and nothing to be ashamed about.
I do like 100-200 panels a week depending, and I don't use sketchup.
(Then again I don't have backgrounds in every panel because I feel like it would steal attention away from the dialogue.)
I have considered it tho because fuuuuuck backgrounds. But at the same time eh I dunno if I can be assed to learn to use sketchup.
Jk. But thanks for telling me anyway!
