Newbie runs amok with VizRender!

Cad Racer · November 20th, 2003

Ok we just got ADT 2004 in the office and I've already been asked to render something with it to justify the purchase. So with no training here I go!

I modelled the house the only way I know how right now and thats with solids.

I'm reasonably happy with the result so far. And as its a WIP I still have to add in the foliage and dress it up.

It was my first try at radiosity lighting with the sunlight system and I read as much as I could in the posts on this forum to get me a head start on settings but I still have much to learn!

Any ideas why my grass texture isn't showing up? I applied it the same way as the stone and siding so that one has me stumped. And I'm still trying to figure out the best way to get a sky in there.

Anyway, Comments and Critiques are more than wecome! I want to learn how to improve my work and I enjoy the community spirit here.

What type of exposure did you use? This can help improving the rendering.

Did you use meshing on the model (subdivide modifier or the global meshing in the radiosity settings)?

Did you use regathering?

For a WIP and a first one, it's certainly not bad. 5 minutes in Photoshop could do a miracle though and impress your boss

Here is an updated image. Its getting better. Still needs a bunch of work on the foliage. And my trees are really dark.

I set the exposure to like 50 brightness and 60 contrast. I did use regather and global meshing. I can post my exact settings later (I'm not at the office now).

Critique away!

Hi Cad Racer,

very good beginning!

I guess the first image had a good balance in the light and shadow areas. Raising the contrast(image 2) caused some areas to be too dark.(left side)
I would keep the firts settings and try to lower the sun angle to make it brighten the main facade without darkening the others.

I would search for a more uniform grass map.
And the grass color seems a bit yellowish to me.
You could put some mapping on the sidewalks.
(Maybe you are planning it already)

The trees are really dark so it´s difficult to say something. But even in the dark they seems a bit strange to me, like a kind of mesh involving them. they use some oppacit map material?

I would also keep the sky clean for this stage.
anyway I think this one is too dramatic and a bit oversaturated (besides overused !).

Try some bushes, mountains or fences to hide the horinzon. (behind the house)

Maybe some tree shadows or bushes could add something to the foreground. It´s a little bit overused but usually works!

The stones seems a little bit green to me, and
you could add some red to the roof to make the image more colorfull.

Keep working!!!

Well I'm pretty much out of time for this job but I'm happy with the result. I think I have progressed pretty good with the image. I used some of the basic Bionatics trees for the background and tried to fix up the grass in Photoshop. I went with a straight gradient for a sky as the bitmap skys seemed to real when the rest of my materials have a much more CG quality about them. Not that thats a bad thing.

I still welcome any comments or Critiques as I

Hi Mike,

This is pretty good. Here are some things you might want to consider for next time:

- It is usually better to show the grass level above the paving. Fillet the edge to make it look more natural.

- The stone facade could use some bump mapping - you could try copying the diffuse texture over to the bump slot.

- The sky is a deeper color at the zenith than it is at the horizon.

Fran,

Thanks those are all good suggestions. I wanted to do a bump map for the siding to give it a bevelled look too but couldn't get the material to work right in Vizrender. All my previous experience was with Viz2 so Now I've got a big lot of catching up to do with all this radiosity and stuff. And even the interface for the Vizrender is SO different from Viz 2.0 its not even funny! Lots of learning to do! But its fun.

Hey Mike,

Good progress! :winkgrin: :winkgrin:

I saw you add some light fixtures and water pipes.

I think what Fran said, is that you should keep the grass level above the paving, and fillet the edge of the grass near the siding.

I still think the shadow on the grass (left) is too dark.

Trimming part of the grass, gave more balance to the image, and the color seems much better now.
But a good tree shadow could help hide some grass problems!

Although what Fran said is right about the gradient sky,I have seen many drawings with this stylized sky, and seems very interesting.
Besides, it merges well with a blank paper.

If you still have time, keep working!
