I am after some help with the perfect settings for exterior renders - I don't know what a lot of the settings means and don't particulary have time to experiment with them more than I have. Can anyone suggest settings that have worked for them when creating raytraces of the exterior. - lighting, ambience, shadows, etc....

Try this set-up.

 

- Set the North pointer and Sun to your liking. Leave the suns light strength and colour as per the default. You can also use the generic sun if you wish.

 

All other settings are done in the Raytrace DBX only. If I do not mention an item then it is to be turned "off" (unchecked) or set to "0".

- General Tab - Set size to your liking, set number of passes to 50 max.

- Lighting Tab - Ambient Occlusion Min .5, Max 7. Direct Sunlight 2

- Advance Tab - Photon Mapping "On"

- Image Properties Tab - Brightness 46, Contrast 59, Saturation 38

 

Run your Raytrace

 

Here are three exterior views based on these settings. All models and materials are default Chief. They run 50 passes in about 7 minutes on my system, they are actually pretty well done after 10 passes.

 

exterior A 50 pass 6 min.jpg

exterior B 50 pass 8 min.jpg

exterior C 50 pass 6 min.jpg

 

Here is a late night scene.

 

These are the only changes I made to the above.

- Changed backdrop to a much darker version. Took Chief forested road backdrop and knocked down the highlights in Photoshop.

- Changed Direct Sunlight to .05. Wanted to simulate some moonlight contribution.

- Changed Ambient Occlusion to Min 0, Max 2

Does any of this help? Please note that there are likely many more ways to achieve this. My method does not necessarily produce Architectural Digest quality images, it does however produce high contrast, punchy pics very quickly right out of the box.

I'm sorry, but I think this thread is an exercise in futility.  There is no one size fits all settings that are going to work for every situation or for every user and especially not for both.  This has been discussed so many times over the years its ridiculous.  The end result is pretty much always a thread with 500 posts and in the end, the only people who really learn anything from it are the people willing and able to put in both the time and effort to really understand what all the various settings control and to both learn and test various ray trace settings, lighting settings, lighting placement configurations, material settings, material usage, north pointer settings, sun angle settings, etc. etc... and various combinations thereof.

[sarcasm]Thanks Graham but those settings aren't perfect - could you try again? And as I said I am much too busy to learn myself - thank you.[/sarcasm]

I did not say they were perfect, there is no such setting. Post a pic of what you got, maybe you have something turned on or turned off that should not be that way.

Hi Larry - Had a very strong sense that you were pulling my leg, especially when you reiterated that you were "too busy to learn yourself". Now that you have fessed up my plan for today's responses has been disrupted. I'm sure other members will be disappointed now, their envisioning of me working feverishly to find the elusive "Perfect Settings" has come to an end. :)

PS - Will be posting some more results shortly but need to work on finding the "Holy Grail", the "Treasure on oak island" and a few million "Fraudulent Voters" first.

Look in California B)

We have at least that many.  There are also some in Chicago.

Shouldn't there be a "perfect setting" button on the ray trace dbx?

:) Mine is located on the Chief startup menu right

below the "Auto-Build Entire Model" button.

 

Seriously Anthem, what you are asking for doesn't

really exist. I think Michael summed it up pretty well.

 

Just for an example here is the same camera shot

Ray Traced with 3 different simple 3D backgrounds

and different material properties. It all depends on the

effects you are trying to achieve.

Nighttime

Here are examples as to how lighting determines just about everything. The Raytrace settings are the default "Indoor High Quality", 1200 X 736 px.

 

1st pic - Sun "Off", Lights "Off"_ 50 passes, 1min

2nd pic - Sun "On", Lights "Off"_50 passes, 12min

3rd pic - Sun "On", Lights "On"_50 passes, 27min

 

No matter what settings or materials you play with, there is no way that I know of to make the 1st or 2nd pics look any good. Only once the lighting is properly set and balanced (3rd pic) should one even consider playing with a materials properties.

Perhaps I should have should have said "perfect" I am very clearly aware there is no such thing. I was simply after some settings that worked really well for someone else. And while I said 'I did not have time' I simply meant 'that day' as I had to produce some images as soon as possible and the settings I was playing with were not producing what I wanted. I just wanted a little guidance for an afternoons work, not my whole career. If those of you who had nothing nice to say why didn't you just say nothing? Rather than taking the mickey out of my question, you could have looked past it and moved on to the next person. The forum is there to help others, not make them uncomfortable. For those who provided some setting guidance thank you so much. I will play with these a little today to determine what does and doesn't work. Please don't reply to this message now as I don't want to continue this conversation.

Just another example based on the 3rd pic in my last posting.

 

The 1st pic has a yellowish color cast to it and lacks in clarity, here it is in 1200 x 582 size. For the 2nd pic I just adjusted the 1st pic by only using the "Image Properties" controls after Raytracing. Everything has been done within Chief and the Raytrace DBX.

50 passes look amazing (what you all have posted above). But what pc are you running ? 10 passes takes me 8 hours on high quality 2048 Pano.

I have i7-6700k 16GB ram, AMD rx 580 8GB

CPU maxed, ram 50%

GPU spikes here and there.

there are two threads running currently dealing with Ray traces..... but most are not  running Pano  or at 2048 .... ie try  1280x720 with no point lights  15 passes in 6-8 mins ....for interiors anyway is working well with settings from Graham Korbey in the 1st link

      I keep upgrading and all of a sudden I do not have any of the basic Lighting fixtures like a 4' Fluorescent surface mtd fixture.HELP

      A bit late in the day to be starting an old topic. What the heck is the deal with random wall lighting issues in PBR? I've tried every toggle and adjustment I can find but I can't get a couple of walls to display properly. It's clearly not a specific lighting issue because the problem is with a few walls. I recorded the PBR adjusting itself and somewhere along the way it gets it just right...but then just keeps on going. All I'd need is a slider tool so I could manually reverse / forward that process and then stop it where I'd like it.

      And while I was working on this I had an epiphany! I added a wallcovering to my offending walls, using the same material, and BOOM! They all play along now! This could possibly go in the 'tip and tricks' section.

      I've been an active user of Chief Architect for about 15 years now. I am currently using the X11 and have an SSA.  In all of these years using the software I have been frustrated with a couple things in the electrical area. First was the terrible placement of electrical connectors, they were never placed in a way that was visually appealing. I was always wasting time adjusting the lines after placement just to make them look nice on the plan.  Thank you Chief, in X11 the lines now, most of the time, place in a visually acceptable manner. A great time saver when doing the electrical! 
       
      The second, frustrating issue is the lack of programming to address the floor-to-floor light switching. I have over the years visited ChiefTalk hoping someone had a good solution to address this issue. I have never liked any of the proposed solutions, namely placing the correct 3-way or 4-way switch on each floor then placing cad arcs or splines to represent the electrical connector. I felt it to be a time waster and it just did not feel right using a cad line instead of an electrical connector. 
       
      So, in response to my frustration with floor-to-floor switching I came up with an idea and ran with it. I created two floor-to-floor connector symbols. The symbols are identical except that one is designated as being switched and the other is not switched.  Both are, in plan view, a 2" circle, defined as an electrical item, In 3D they are a 2" clear glass sphere and attach to the ceiling, being virtually invisible in a 3D rendering. When I am doing a floor-to-floor switch connection I place the switched symbol in the stair well then connect the switch to the symbol. The switch then automatically changes to a 3-way. I have a set of text labels that I then place over the switched symbol to indicate the usage of the switch, i.e. "To light above", etc. I have attached an X11 library containing the two floor-to-floor symbols, (switched and not switched), and the text labels I use.
       
      I hope these will save you a bit of time. Enjoy!

      Hi 
       
      When I render PB  the image always looks darker than in the standard view and in  ray trace  .
       
      When I look at the online videos for assistance there is mention of BLOOM and IMAGE .( Changing intensity, contrast etc).. I do not these options on my tool bars ,  Are these options only available in RAY  TRACE
       
      Thanks

      HI All
      I have either imported a sketchup light or created a new light in CA but always have to add a point light to this object separately.  And I don't know about you, but sometimes it is very difficult to click on the point light in a plan and move it around... even if I have only lighting displayed.
       
      But I though about adding in the light BEFORE I convert the object to a symbol.  But alas when I place this new object (assigned it to the electrical layer) the point light is not there.  
       
      Is this just a necessary evil of creating custom lights, you have to always put in a point/spotlight in with it?  I even tried to group the the point light and object and couldn't...
       
      Any tips?
       
      thanks
      melissa
