help my houses!

Below is the stage I have got to with the houses I am trying to create. In the next post I'll show the picture I am working from/trying to replicate.

Can anyone point out ways i could improve what ive got, and anything else I could do to make a final image more closely resembling the one I'm trying to copy. Im really pretty embarassed of my image, i'd like to produce something that looks at least a little more half way professional. I dont know if my issues are in the texturing, or the lighting, or more the post production side of things? probably a little bit(alot) of each.

The thing that you need to learn more about is rendering.

hey Ben,

The image you are working from is 3d!

you could try switching to mental ray, and use physical sun and sky under the enviroment options at the bottom of the mental ray render options. if you do this you should dsable default lighting. (this is near the bottom of the common render settings),

...but before all that, do you have a bump map on the model? and have you beveled the edges of the buildings? they look kinda sharp. (maybe thats just the anti-aliasing)

*Bump maps
*Sky dome + lighting / physical sun and sky or something
*Texture the street
*Create glass material for windows (reflections + specularity)
*Improve texture for roofs
*Windows on roofs and on first floor aren't accurate. so is that thing above the doors(sorry, forgot how it's called)
*Model the gates
*Create grass (paint effects probably)

Nice start overall
Benny

this is good. Thanks guys. I havnt bevelled the edges and it hadnt occured to me to do so, so that'll be step one.

Ive wondered for a while how to add an image as a background, like a sky, or something, so i will look into all this. Every point sounds good.

thankyou

The first thing I noticed was the proportions, the houses in the ref are deeper, more space. And the bricks are too large, it makes your houses look even smaller. The image for the bricks in the ref looks like the same image they used for the roofing except with some color changes so you could try that as well. Its a great situation to use MR physical sun but you're going to have to plug gamma correct nodes into the textures to prevent them from getting washed out. And since you said you wanted to replicate, there are a few details that are missing.

Well pointed out Genny on the gamma front, like most things MR sun/sky aint the magic bullet and needs a tweek.

well, i just rendered out this in about 3 minutes. I was quite excited about looking at physical sun sky, so i jumped ahead to that. this is with just the default settings, all i did was raised the sun up in the sky. I can see how its given everything a softer look.

GecT, I wanted to get something that had more of a professional feel. In 'replicating' the picture, i mean more in the overall quality of the render, i see what you're saying about missing details in the brickwork, the depth of the houses e.t.c. The roofs are also taller in the picture im working from and the proportion of the window roofs to the rest of the roof is severely different. I will be trying to remodel some of the parts though, and ive hit some problem with my textures now so i'll be redoing some of them. gonna call it a day for today.

will post updates over the next few days. I feel up for it now, got some good issues to get to grips with..

It looks like you have multiple shadow sources. I don't think Physical sun and sky should do that user added image
Anyway, look for some more tweaking of that one - horizon height, blur etc. (stuff I've seen in Maya's help. take a look there...)
Also, the render quality is good enough for test renders but you're going to have to raise it later...

if you're rendering with multiple lights, you ARE allowed to turn off 'casts shadows' on some of them to get the idea of one light source with bouncing light...

also please do increase your anti-aliasing quality... seeing the jaggies on the roof and front fence are kinda distracting.

otherwise, in order to attempt to duplicate the image you saw you'll need a lower camera angle, a different background color, and brighter and warmer colored lighting. that should be enough for starters.
