Critique my rendering

Anonymous — Thu, 11 May 2023 10:35:08 GMT

I would like some constructive criticism on this rendering I produced with lightworks. I modelled this scene very quickly just to play around with lightworks (I have nothing better to do in my holiday). Any advice on how to make it better would be appreciated.
I feel like I'm starting to get better using lightworks, although its proving to be a pretty hard lion to tame. Perhaps when I get a job, I'll be able to buy Dwights book - but until then, all I have is the forum.

It's very nice

It is nice.
I'd like to say, if you need my opinion:
The Entranc area should be little bit light....in a moment the entrance are is dark area. It can show little bit negative image.

Beginner or intermediate this rendering is useful to any client. As a rendering I feel you should first fully explore the project with your OpenGL engine, a slightly different viewpoint might add excitement, try different lens values too. No need to include everything in the image, I feel you are reaching to include the distorted car bumper, lic. plate, etc. The entourage person is not convincing. We have the famous Girl in Red, you have given us the Girl in Black. Pops right out of the image. Great detail, perhaps play with post processing a little in PhotoShop.

First off, I agree that's it's a pretty decent rendering. A couple of things that are uncomfortable. One is the severe perspective. I would pull the eye point back with a more narrow field of vision to feel more like a standard 52mm camera lens, rather than the "wide angle" feel. The car really draws my attention and it shouldn't. That problem will be somewhat ameliorated by pulling the eye point back.

Is that round disk on the left entry wall a light fixture? If it is, put a lunimaire in there to provide some soft light on the wall and water (?) below. Keep the intensity down so you don't lose the nice shadow at the front door.

I would also suggest pulling some low plants around the corner to the front on the left side. It would soften that left corner a bit.

Maybe one last comment, and that is that the driveway and walkway are pretty strong and is maybe not so complimtary to the house color and grey car (Toyota?). I would go for a more natural finish like an exposed aggregate that has some color variation in it and has a much smaller texture scale.

The grass looks really good, you've got a good image map there.

We've used Lightworks in FormZ quite a bit and we really like it for exterior views. A lot of time we copy the sun and rotate the copy about 80 to 90 degrees from the primary sun, then turn the shadow casting off and reduce the intensity to create the feel of reflected light.

Thanks to everyone for your comments and great advice. My skills in producing decent renderings will benefit a lot from sharing this image. I'm going to make another version with everyones advice considered and I will post the results later.

Is there anything you had in mind that would make this rendering better? I am competent using photoshop, although I didn't do anything to this image as I felt there was not much of a need for 'post processing' in this case. Perhaps there is though?

I had a feeling this was the case. It seemed okay without the car, but now it does look pretty bad. I'm going to try again with a better view point and not such a wide angle.

Heres the texture I used. I like it because it's quite large, and it is hardly noticeable where the texture joins. Im not sure of where I downloaded it from.

Excellent work!

Suggestions:
1: Desaturate 50% in Photoshop
2: Crop for better focus - concurring with the distorted car and repeated foreground plants being a distraction.
3: Mid-level correction to 1.40 for better luminance
(all images have too much blackness) in Photoshop
4: Small amount of diffuse glow added in Photoshop

Note: excellent graduated light on shadowed wall!

Option to make softer shadows: increase sun divergence using the sun object with 10 light sources at 22 degrees divergence.

Not so much a critique of the rendering - others have covered that - but, what is going on with the roof here? It looks like the shell of the house is some kind of precast concrete box, or drainage structure. I would like to see a section detail of the roof/wall assembly. Right now, the thickness of the roof will not accommodate structural framing, insulation, roofing, flashing, gravel stop, interior finish, etc. etc.

Re: Critique my rendering

Dwight — Fri, 06 Jan 2006 04:05:56 GMT

That's why they call it "virtual building."

We know all about virtual building here in Vancouver where the condos all leak because they are built with full-scale foam board.

mate, one thing i've learnt whilst i've been here in NZ: flashing is what sleazy old guys do in the park, 'structural' framing will work if it looks like the roof isn't going to collapse, insulation's optional and 'falls' are just for water coming down off the mountains . . .

it'll work over here . . . trust me!

Nicely done. Nice ambient light, soft sun shadow edges, reflections (including context!). Nice water surface.

I agree with all of the previous posters' comments. The first impression was of the distortion. Discussed.

Second impression was that the sun angle did not match the illumination of the bitmapped vegetation (the dicey part of using photographic entourage) and that the sky is too dark for the sun position.

Very small nit-picking:

The concrete curb of the pool in the foreground meets the lawn at too clean of an intersection... suggest adding small bitmapped blades of grass, or the GDL grass part someone posted in recent months, or painting a bit of the edge with a grass-shaped brush in Photoshop.

Other minor nit is the pavers of the driveway ... use the Align Texture in 3D command to shift the tiles to show a full tile at the left edge where only 1/4 to 1/3 of a tile now shows... or perhaps add trim slab (concrete? brick?) at the edge of the driveway.

Did you use the sun-from-hades trick of Dwight's book (from a fellow ac-talker whose name I forget at the moment)? The ceiling above woman-with-cell phone seems a bit dark ... given the sun angle, the glare from the balcony would bounce and illuminate it better than shown.

Good work.

Karl

Now that you point it out, I realise that my image is far too saturated. My laptop LCD doesn't help either; everything appears less saturated. 50% does seem like a little too much, although its probably my screen. Thanks for the great advice!

Re: Critique my rendering

Dwight — Sun, 08 Jan 2006 01:24:28 GMT

These values are all over the place considering the lack of calibration we have.

My posting was of a 50% reduction of saturation - in line with the work I put in my book, so I know that my system is accurate.

This saturation and blackness issue just goes on and on. I get mail from people with no color sense challenging this approach occasionally.

Let them continue with bad taste.

The truth is in the print...... but ArchiCAD users with open minds should experiment with my ideas within their own systems.

Dwight,
one question, how do you know that the "sun object with 10 light sources at 22 degrees divergence"

Isn't it in your book that sun object should be 76 light sources and 90 degree?

I am so confuse. I am new with lightworks.

Re: Critique my rendering

Dwight — Sat, 14 Jan 2006 01:23:46 GMT

Thank you for buying my book. It was hard work and took a long time. Be sure to register to get the special files and materials. I hope that you will attend one of my seminars this spring.

There is no absolute approach to setting the Sun Object. I experimented with many setting before I arrived at what was reasonable, balancing light quality and rendering speed.

Considering that the sun object can have between 1 and 20 individual light sources contained within it, and those individual light sources are arrayed in the sky measured by divergent degrees, a number of factors matter:

-- the softness of shadow YOU want.
-- the size of the rendering measured in pixels.
-- whether or not bands of shadow are seen when a graduated shading is needed.

The larger the rendering, the more light sources are needed to make really soft shadows.

Once you set up the altitude and azimuth of the sun and establish your rendering size, to eliminate banding, increase the number of light sources or reduce the divergence angle.

ashley wrote:

You are certainly right when you say that you are confused.

Seventy-six is not the number of light sources I recommend, but rather, the number of trombones that led the big parade.

You are trying to trick me.

When, in the "LightWorks in ArchiCAD" Quick Start Guide (page 26) I recommend an "UnderSun," that object is placed at -90 degrees to shine upward, defeating black soffit disease.

Thre are still a handfull of ArchiCAD TALKERS who haven't bought my book. Don't miss out.
