Lighting and interior

[Sean Casey]

Hi Guys,

I’ve offered to help a friend of mine who is a young furniture designer maker. He has just had his first commission piece which is to design and make a bookcase. He has developed a design and has sketched it up. I have been mentoring him and while he was having discussions with his client, I measured up the corner where the bookcase is to go. In order for him to give a quotation, I have recommended that he improves his CAD skills as it can be a huge leap of faith for a potential customer to part with their money on the strength of a thumbnail sketch on the back of a cigarette packet! I have recommended AutoCAD together with AccuRender and have offered to model this project for him to show him what is possible. Although I am proficient in AutoCAD, I am still getting to grips with AccuRender. So I was hoping if I was to upload a model, complete with materials of the room interior where bookcase is to be situated then one of you could have a look at it and recommend improvements. The first problem I have come across is while modelling the room (I used Peter Milner’s template interior as a starting point, and copied his window into mine...thanks Pater) is I am getting a great effect with the light streaming in through window but was wondering should I use an interior light source as well?

I would welcome any feedback which would improve this set up as once perfect it can be used time and again. Thanks in advance..Sean

Here's my few suggestions for what they are worth.

1. Increase ambient light & skip the interior light fixtures. What do you have light bounce set on?

2. Take a look at the front corner of the hearth, something funny is happening there. It looks like it has an edge not meeting correctly.

3. Increase the scale of the stone pattern on the fireplace. This should help calm it, everything but the bookcase should be background.

4. Let it run longer and shadows should even out.

5. Use image in window where it is now black.

• Use interior daylight preset.
• remove the glossiness of ceiling.
• Increase indirect bounce to 2.
• use glossy shader for walls.
• Tag glass only in window as daylight portal.
• Add another window on the opposite side of the room to help remove the dark shade on the windowed wall.

Thanks guys,

I'm really humbled by your response - for taking the time out of your busy day to feedback. Will certainly apply your feedback to the scene and will give you a progress report with the bookcase in situ. I expect that too will need some work. Thanks again, to the rest of the forum members do keep the advise coming. Cheers Sean

Thanks to Wayne, Akinlolu and Jorge for your input which I have applied to my scene. I have outlined the steps I have taken below for the benefit of any other beginner who happens to read this discussion.

 

1. Increase ambient light & skip the interior light fixtures. What do you have light bounce set on?

I have increased the ambient light in the Lighting tab>Advanced>Ambient from low to medium. If you mean Reflective Bounces, these I have not touched and they are currently set at 3, as for the Refractive Bounces these are 8.

 

2. Take a look at the front corner of the hearth, something funny is happening there. It looks like it has an edge not meeting correctly.

The front edge of the real hearth is a wedge shape which would explain why it looks strange but in this instance I have modified it.

 

3. Increase the scale of the stone pattern on the fireplace. This should help calm it, everything but the bookcase should be background.

I’ve increased the size of the marble texture from a scale of 1000 to 2000

 

4. Let it run longer and shadows should even out.

I let it run all through the night for 7 hours making 334 passes

 

5. Use image in window where it is now black

Thanks, I’m really pleased with this effect which I found in the Walkabout window>Background tab>check Background Image

 

• Use interior daylight preset.

Changed to daylight preset which I found at the top of the lighting tab which by default was set at <custom>

 

• remove the glossiness of ceiling.

Under Material tab>New Material>created solid colour

 

• Increase indirect bounce to 2.

Under Lighting>Advanced>changed Indirect Bounces to 2

 

• use glossy shader for walls.

Wasn’t sure how to do this? Does that come under Template:Glossy??

 

• Tag glass only in window as daylight portal.

Not sure how to do this?

 

• Add another window on the opposite side of the room to help remove the dark shade on the windowed wall.

I quite like the effect that Jorge created and may experiment with adding another window at a later date.

 

Now this is probably where I run into conflicts what with trying to apply all of your recommendations. I am learning that everyone has their own personal preferences but having seen an actual rendering by Jorge which I quite like, I am going to try to use Path Tracer for the first time by applying Jorge’s setting to my scene (possibly over riding all the settings I made earlier!)

 

Well ran rendered scene all night and have attached the rendered image and drawing. I will withhold judgement as to the merits of using Path Tracer as the image still lacks clarity which would come if I was to let it  run longer? I will do the Pepsi challenge at the end with Path Tracer against standard method.

 

Will upload scene complete with bookcase for your review, many thanks Sean

Thanks Kingjin - I like your rendering which looks like you have also used Path Tracer. It does look more natural than my effort, I have light streaming in through the window which does look a little harsh however my only criticism is that it does look a little cold without light coming in. Could you be so kind as to upload your amended drawing so I can look at your settings. Ta Sean

Just keep increasing cloudiness until you get the right balance.

In the example below the best balance would be somewhere between 0.4 and 0.7.

Cloudiness 0.0

Cloudiness 0.4

Cloudiness 0.7
