Ok mates, for the next MGAC, I propose you to make a building of your town/country, that you particullary like. It could be a monument, a house (your house ?), a bridge, a castle, a church, a museum, a sky-scraper, etc... Make us travel !

Edit : by "your country", I mean your all state, like Canada, Brazil, China... Hope I haven't been misunderstood.

Then I'll integrate all your works in a little virtools scene. Nothing much, just to have all works together, and the possibility to turn around.

Specs :

Triangle budget : 500 (both sided triangle count as two)
Texture budget : maximum 512*512 of whatever you want (1*512 color map, 1*512 normal map...) Declensions are allowed (4*256, 8*128, etc...)


Guidelines :

You must provide a viewport shot with textures, a wireframe shot with the tris count, and the textures.

Then I'll need all the scenes/textures to integrate. If you don't want to post it on the forum, send me a pm.

Deadline :

Monday 19th Feb 2008 11.59pm GMT

Bon courage !

oeh... cool... I am sorry to say it's gonna be hard for me to make the deadline with stuff going on all over the place the coming few weeks.. but I'll definitely try!

And a big cool :thumbsup: and thanks for using the idea... as well as going for buildings... it is what I would have proposed.. but then just fronts.. like in movie sets :)

However I am afraid I don't live in that spectacular a town.. so I'll choose something that isn't that beautiful or spectacular but rather normalish ( I think that really will look better anyway :) )

those texture specs are something I don't look forward to by the way... nice going for pushing us :p
Now that I think about it... maybe I should aim a little lower with texture tiles I am gonna use and try to make something a little bigger then just one building... hmmm I'll get back at you about that!

Cheers mate!

well, the deadline could be changed...
No matter if the model isn't spectacular. Just show us some place you like with your modeling and texturing skills :p
I precise you could use 4*256, 8*128, etc...textures maps. So you could use tiling textures and a little lightmap.

Great!, I can't wait for Dominance War III, but this MGAC should hold me off.

Ill start later tonight, :)

This house uses one 512 sheet for the diffuse (and then one for the spec and one for the normal) so it's certainly possible to get some nice texturing going with good usage of tiling textures and some decals.

nice example :)
This is exactly the kind of thing I thought :thumbsup:

matsman
02-07-2008, 03:20 PM
yeah... I thought something along those lines as well... I do think the grunge looks very repeated throughout though... but my first problem is choosing a subject and making some good ref pictures.

Lets do the texturing later...

I think i will join this one, will be my first. very fun that you choose a collaborated project style. we have soem interesting buildings in my city so lets give it a try.

Clanker

Because there's a bit of work here, and it's not always easy to find time, I give you an extra weekend.
So the deadline is now Monday 19th Feb.

Dont know if im going to be able to join in but is the equivalent of 512 maps allowed? like a mixture of 128's and 256's that add up to the same? to allow for tiliong like the model Urg posted?

After a lot more work than I expected, I think im done the MGAC. It was great fun though, and I learned from some valuable mistakes.

Anyways, heres my little story. I decided to make the Vancouver Look Out Aka "Harbour Tower"
heres a lil reference.

http://media.expedia.com/tshops/media/van_trolley/tower_trolley.jpg
http://media.expedia.com/tshops/media/van_trolley/tower_trolley.jpg

Now I don't know what I was thinking, because im not really experianced at textureing/uvmapping. But I liked the building and thought it would be cool, so I gave it a go.

First I modeled and it was far over 500 polys, sitting more in the 1200 area, so I deleted the round thing at the top and modeled it with lower polys as well as the roof and that circular area on top. Still I was around 800 polys, and I realized that I was using way too many polygons at the antenna so I deleted that and replaced it with a X alpha map crossed poly type thing so I though I would just be able to use a alpha for the flag. Yay after a bit more tweaking I got the model down to 497 Polys.

Heres the Model:

http://img172.imageshack.us/img172/7940/polycountermodelsc9.jpg

Im pretty happy with it, for its poly count.

Next the hardest part that I had to experiance was the texturing as you can see in the above texture I used a lot of tiling as well as couple alphas. Heres the list of textures,

7 Textures: 126x56,128x102,32x32,16x96,22x128,96x96,126x78
- As I said im not too good at textures, so maybe ill add some more detail in throughout this week if I have time. = ) But right now they're pretty small textures and the result is decent.

Heres the textures on a single sheet:

Lol, not much really there.

Ill probably make a spec and bump soon.

Now for the actually finished product:

http://img511.imageshack.us/img511/9445/harbclipzc1.jpg

Well heres probably the last bit of work I will do on this building.
I now changed all my textures to proper sizes. I also made Specular, Normal, and Bump maps. As well as tweaked/changed some textures.

Textures Now Are:
Spec, Bump, Normal, Diffuse of: 128x32, 16x128, 64x64, 128x128, 128x128, 128x128, 128x64

Enjoy.
Good Luck everyone!

Hey Matthew. Nice work :thumbsup:

Nothing much to say on the modeling, it's pretty clean and optimized. Good job. Glad to see you lose your head to attain the poly count :p

Now the textures....
(I wont penalize you for that so don't panic, and don't make your textures again !)
You are using non-standard resolution for your textures. Always use textures with resolution in power of 2 (2,4,8,16,32,64,128,256,512,1024,2048,4096...). So instead of 126x78, use 128*64 (you can stretch a bit your uv's). Some operations like mipmaping, certain address mod (warp, mirror, ...), certain hlsl shaders, dxt1 and dxt5 formats, are not supported by graphic cards with texture resolution in non power of 2. Furthermore, I think the textures are interpreted slower.
But tiling is pretty cool =)

Thanks Clanker.

And yes, I do know they should be powers of two, I guess I got a bit disoriented after all that work in like 1 sitting almost. But yeah if I get a bit of time this week which I should Im gonna actually redo the textures, like just work on em a bit and change the textures to more acceptable sizes like you said. :)

Hello!
It`s very good idea to build the MGAC city, I love it! So I decided to take part in building.
Here is my current WIP - Khotyn fortress - http://forums.cgsociety.org/showthread.php?p=4947037#post4947037

Well i decided to try and enter this, but it seems like i wont have the time to do any more on this, so its time to post it ;)

As i said i wont have time to finnish it, so the textures isnt good at all. and it ended up with 464 tris, and it could be much more optimised there to.

Hi socius from Sweden !
Welcome aboard :)

So, your modeling is pretty simple, but it's clean, and you have all my respect for doing something with blender :p

You could have easyly removed some faces, like the floor that we'll never see...

You could have used tiled textures too (since patterns are often the same) or include a bit of lighting and shadows in it. Your UV layout isn't optimize but I think you know all that. So it's not perfect, but I thank you for passing a bit of your time on this subject. I know that's not always easy.

Glad to see some people post in this thread for the first time.

Hy, again!
Previous participants did good job! And I think I`ve finished my work. It was the real challenge for me. Thank all for help.
As I already said I have tried to create lowpoly copy of Khotyn fortress, Ukraine. See more about this fortress - http://en.wikipedia.org/wiki/Khotyn

And the winner is :

Yunga !!

I think your model/textures are the most detailled. Maybe the choice of the building was too ambitious, not really easy to do with those specs (not much tiling). So, details on texture are a bit blurry. But there are some really good things here. Maybe the fortress will have been more integrated with some dirt or grass down the wall. Try to think to all little things that make a thing looks more real.

MatthewNovak : You model is great too, perhaps a bit simple. You have smartly used tiled textures and alpha map. The model is really clean, but textures lack a bit of details.

socius : your model is a little less good. I know you did'nt have the time, but your UV layout isn't good. You've lost a lot of space here.

Anyway, "merci beaucoup" for your participation to this contest :)

(it's so hard to translate my judgement in english, hope I haven't hurt your feelings :D)

Yunga, it's up to you !

Yunga
02-19-2008, 11:42 PM
Wow!...
Well.... I didn`t expect for this result.
Congratulate all comprtitors.
Thanks all of you, guys, for help and advices, without that ones I couldn't do my enrty.
Clanker, I really like your idea about the MGAC city, and if you steel need scene and textures let me know. Unfortunately this MGAC wasn`t too crowded to make huge city.

I`ll think about idea of next MGAC. If you have ones give me a hint, couse I`m new here.

Best wishes, Yunga.

MatthewNovak
02-19-2008, 11:44 PM
Lol yunga, you deserve it. When I saw your refs I thought you were crazy. Like 500 Polys for that is not a easy job. For 500 polys you squeezed every bit of detail out of it, tiling would have helped on the walls, but I can see you put quite a bit of work on the texture too. You did a hell of a job = ) Gratz!

02-20-2008, 06:44 AM
Yeah it's not a huge city for sure :p But I'm still interested to integrate your works. I mean,
we do real time things, so IMHO, it's more interessant to have the possiblity to turn around than just have a flat image.
