Hi Scott - The big culprit on the exterior is the intensity of those post cap lights. I dropped them down to 4%.

 

- Changed the background colour to black 15% luminance

- Ambient Occlusion, min=0, max = 1

- Sun intensity=0

- Unchecked Environmental light

 

Image Properties

Contrast = 88

Intensity =31

Colour Correction =0

 

Brightness = 46

Contrast = 81

Saturation = 45

 

This is after 10 passes

Will now take a look at the interior.

Graham,

 

That was quick! You're the man! Now this is practical help I can use. Can't wait to see your comments on the interior.

 

i'll be on this first thing in the AM to try my hand at some of my own. 

 

Thank you so much!

Hey!

Me%20too_zpsf91dz4xd.gif

 

Here is a remodel project in progress for a neighbor up the road a piece.

Maybe not as impressive as Bob's lake house but it's always nice to see

your design taking shape in actual brick and mortar.

As always 100% Chief. In light of the fact that we have had 15" of rain in

the past 6 weeks, and with more on the way, the owners are reconsidering

their landscaping options so that's a blank canvas for now.

Hi Scott - As mentioned those cap lights were the reason for all of those speckles. When this happens it's best to turn off all of your lights and then turn them back on one light type at a time. Run a quick Ray Trace in between to find the light type that is causing the issue. Once you find the culprit reduce the intensity to eliminate the speckles, I usually do this in 50% reduction increments. Also, this is typically a point light issue, so best to focus on them first.

Anyone have an idea what the little marks are ... both are ran in pano  .... difference of the two views is the one without marks has three lights off two in living rm and one in hall and is done in 10 passes  and one with the marks is 20 p also  changed the backdrop from sky to forest ..but would not think that would effect anything ? I do have the three lights set at 25w ... Any ideas would be great ..maybe Chief has a bump map for dust

Suspect that the ceiling fixture in the hall by the stairs is too bright. Reduce it's intensity say 50% and run again to see if the speckles diminish or go away.

Thanks again

 

Just look at your cabinet details drawings .. nice ... I do somewhat similar and then send off to a custom cabinet maker but he is responsible for onsite measuring then adjusts my plans.

Scott - Had a chance to look at the interior. The main issue I found was that there is not enough lights to properly light the scene and their intensities needed to be adjusted.

 

Lighting

- Added some additional recessed lights and set them all to 30% intensity,cut-off angle 110.

- Reduced the intensity of the pendants to 25%.

- Only lights in the scene are turned on.

 

Materials

- Made counter top reflective 30%.

- Changed stool frame material to Aluminum Brushed.

- Changed ceiling color to Brite.

 

Ray Trace Settings

- Ambient Occlusion - min=1, max=5.

 

Image Properties

- Contrast=36, Intensity=36, Softness=0,Color Correction=50%

- Brightness=49, Contrast=83, Saturation=40

 

Before Changes (as per downloaded plan)

As Is.jpg

After Changes

Adjusted_116_107 min_PS.jpg

 

I'm certain there are a lot more things that could be done to improve this, but it gives you a good idea as to how big of a difference a few lighting changes can have.

That's a big improvement. I can not emphasize enough that the main key is to sufficiently light the scene and balance the lighting intensities. This is the number one thing to do and only after this is done can one then tweak the material properties if needed. If the lighting is not correct then changing material properties will most likely make things worse not better.

 

Happy Raytracing !!!

Scott - One last render from a different vantage point. The dining table chandelier lights (4) are set at 20%. Everything else is as per my last posts settings.

As you can see the materials are rendering quite well with good texture features and colour saturation. As it is night time there is are nice interior reflections in the back windows and some of the interior lighting is passing through the windows and lighting up some of the deck elements.

Graham,

 

Once again you have gone above and beyond. Another bonus point from me, my friend. Absolutely beautiful! I can take your lead, like the exterior, use your suggestions, and start adding additional tweaks. I've done a few and now beginning to understand the process. 

 

You are the master! Thank you, Thank you!

Graham,

 

You got me so excited I immediately started trying to reproduce your image. Questions:

1) What resolution are you using? Screen? General Tab

2) Did you adjust the Under cabinet lighting? I really like using the custom and % vs. wattage.

3) Ray Trace Options.

Lighting:

- Use Camera View Settings

- Use Ambient Occlusion 0.1 Min 5 Max

Use Environment Light? Yes /No? Does it matter?

Advanced:

- Use Photon ?

- Compute Caustics?

 

Thanks,

Graham,

I adjusted the ceiling in all rooms in the scene to BRITE, as directed, but still getting this line. I'm 5 passes into 25 and it isn't going away.

Hum! Thoughts?

Scott - I think you missed that section of the ceiling with the spray can.

 

The size I ran was 1200 x 587

Environment Lighting off

Photon on

Caustics on

Also, turn off all other lights that are not in the scene, including the exterior ones and those two 3D lights.

Scott - One other thing that slipped my mind. On those island pendants, open their  DBX and under lighting change the offset from base to 15 1/2". That will move the light source up into the glass lens, the light is currently outside of the lens.

I adjusted the pendants, Unchecked Environmental Lighting, It ran much faster. 10 passes in 6:30 min. (see attached).

 

I added an edge to the custom counter top but notice the edge near the closest stool. The first 18" or so on the radius is not taking the molding. Weird! 

 

Running again with new settings and 25 passes.

Here are mine. 100% X9

Jintu,

 

Without question your work is stunning, and I for one appreciate you sharing "What can be in Chief". Thank you for you contribution to our community. The purpose of this thread is to help others learn from Guru's like you so, if you would be so kind...would you please share with us how you achieved such stunning results? I have a number of questions on #3.

  1. How do you select and adjust a background so it fits the scene? In this case, what did you start with and what did you have to do to it make it work for this scene?
  2. Are the tall pines just behind the house part of the background or added trees in CA?

Michael,

 

Thanks for the Grass link, and Shadow board tips. Both are working great. I was wondering what level of success you are finding with Water textures? My limited experience with RT has shown a lot of works is needed to make  water look realistic. Your thoughts?

Scott - check that the ambient occlusion minimum is set at 1.0, the shaded regions seem on the dark side.

      HI All
      I am ray tracing a scene with a 3D plant (from sketchup) and the shadows are showing squares rather than the actual shadow of the plant (1 pass image shown below).  I have purposely moved the sun around to cast shadows to the back of the image as I have found manually manipulating the sun gives much better RTs than using natural sun angles (at least for me).  I attach the skp file and what the plant looks like in the object info window of CA.  Any ideas how to get rid of this square shadow?  I uncheck the ray casted shadows in camera tool pre-ray trace, and it looks better but still ray traces with the square shadow.
      Thanks in advance,
      melissa

      Hi All, I am trying to achieve a ray trace with a tree in the foreground that sort of frames the picture. Attached is an example of my goal- I did not create the attached jpg. I am getting close by placing a tree close to the camera but mostly out of view, but every tree I have tried is blurry. See the saved camera in the attached file. Then I place another big tree closer to the house to create a shadow on the house/driveway. I will crop that tree out of the final picture. Are there any trees CA has that you recommend for close-up high resolution (5500x3200 pixels) ray trace? I found a thread from the old Chief Talk where they had a similar problem and Larry Kumpost  suggested a high res tree, but I don't know where to find one. Here is the old thread http://www.chieftalk.com/showthread.php?34289-Exterior-Critique&highlight=trees+foreground. Thank you in advance!

      Can anybody tell me why I get ray traces that are really grainy?  I can't find a topic on this.  I am using X9 on a mac. 
    • By dJanzenINTERIORS
      When doing a Ray Trace the cabinets seem to be lit from the inside.
      There were no lights added to these cabinets and it seems to be happening every time.

    • By karenmbruns
      How do I get rid of halos/glare that is appearing at crown molding, around door ways, cabinets, etc. in ray trace view? Do I need to change the default for interior ambient light?
