Interior

[pwharton]

An interior scene I put together, still working on it but would love some C & C at this point.

 

Thanks

[jafs00]

maybe some displacement on the rug, and even out the weird light bleeding on the ceiling, I say you're well on your way

[Spooner04]

a funky patch of light specs on the bottom right of the image. Looks good though. Would you mind telling us a little bit about it? How long did it take to render?

[Lazarus]

Looks nice overall, but there are some things that i don't like about the interior.The golden bars that are holding the curtains(doesn't go with the modern theme,inox,chrome maybe golden no), the position of the TV(neck pain if your sitting on the left) and the green and orange combination of the panel and wall.Maybe if the panel was something like wood/wenge material it would look better.

About the render:I'm just a Mental Ray amateur and would like to ask something: Did you use MR sky portals at the windows?The ceiling looks burned out.I get that also.Should you lower the intensity?I don't know.

About the critiques of the interior,that's just my opinion

Thank you all for your inputs, the image was something I put together yesterday to experiment with MR. the seating and side table were downloaded off the web the rest I either created or modified from other files I have to create this scene. There are sky portals in each of the window openings and an omni inside the space beside the camera. I tried adding a photometric light but no matter how high I set the intensity it did not seem to light the scene. I did have an sun system in the scene and it really washed out the wall and the ceiling at the window so I took the light out but the MR physical sky is still set up. I started out using the new pro materials but after a few test renders I changed back to the arch & design materials. The “light specks” are either from a pro material or I need to adjust the fast interloping (Something I just learned about in another of my threads). This is my second try with the sky portal and I get the blow out around the windows. I have played with the multiplier setting a little, I’ll try lowering it more.

Lazarus, Thanks those are things I like to hear about personal or not, right or wrong, It’s why I post these images. Sometime it’s hard to see everything when you are so close to it and it’s good to have some fresh eyes look at it and see what I am missing or did not see. So for me please keep it coming..its how I learn.

I’ll update and repost as soon as I can.

[Lazarus]

Yeah sure, i'm glad i was able to point out few things.I'm waiting for the update of your interior scene.

By the way, why are you using artificial lights on a day setup?To further illuminate the scene?I wouldnt do that...i think that the results are more realistic when you combine the MR sky portals with FG and GI.Then ofcourse you can always further illuminate the scene by tweaking the MR photographic exposure control settings in your environment tab.

I like it - here are some random observations:

* agree about the curtain rod

* I like how the throw rug is slightly askew - nice touch

* some noise in the shiny reflection of sunlight on the right-most side of the room

I suggest either increasing the samples of the material, or upping the antialias

* I'd add some secondary lighting - some downlights or a corner floor lamp

* floor looks good

* couch cushions look good

[pwharton]

Attached is an updated image. I have lowered the levels of sky portals and the ambient lighting. Lazarust the ambient is there to provide the extra lighting that would be coming from other opening (Door Way, Windows, etc.) that would be there normally. This image took about an hour, on a dual Pentium machine at my screen resolution of 1680 by 1050. I have reduced the image size for uploading to this site, I always put the exact time at the end of the file name (00h00m00s).

SandmanNinja, I have upped the antialias in this image but you lost me when you say “increasing the samples of the material” not sure what buttons I need to adjust to do this. I have been thinking of adding light fixtures to the image, so far I have not found one (for free) that I like enough to add, I may have to make my own, I am still looking.

I need to adjust the lighting some more, I think its lost its depth…

[SandmanNinja]

The lighting looks much better.

 

To get to the samples I was talking about, try this:

Press M (for material editor) -> Performance Tuning Parameters -> it generally defaults to 8 samples.

Try making it 16 or 24.

 

 

I always turn on my Ambient Occlusion as well:

Press M (for Material Editor) -> Special Effects -> Ambient Occlusion [x]

 

Just do a quick region render around the noisy area and see if the above settings help.

 

Cheers

What i find a bit strange is that it looks to me like the living room is facing towards North.I get the impression that there's a beautiful day out there but there's no sun light coming in.Can you position your sun so it would appear that the room id facing south wich is the best solution for living rooms.I think that you'll get a better contrast that way, the orange wall will be accented.

[Horhe]

I remember seeingsome past works of yours Philip, these are much much better, congratulations on taking a step ahead. Keep it up

 

Apples are a tad too green.

[pwharton]

Sorry I did not get to this yesterday, it was in the 80’s in Chicago, and I had to get out and enjoy the day while I can. It may be the last we see till next summer. Anyway attached is an updated image. I added an image to the outside of the window but I’m not sure that the sky portals are transparent, anybody know if they are and how you work with them?

I upped the material samples and the floor became more pronounced (due to the same image in the bump Slot?) I take it from the attached image that the areas I circled are the ones you where talking about.

I did have a sun system but from what I read in the help files the sun and sky portal should not shine directly into the interior or should be turned it off. In the first image I posted you can see it blowout the windows. I guess I need to experiment with the 2 systems more.

Horhe thanks for the complement. I would love to get good enough to get a job doing this for a living or for side work one day.

 

Ohh and the "apples" and just green balls that was originally there to bring some of the green back panel into the room.

The attached is an updated lighting render with sky portals in the windows, the only other lights in the scene are a mr Area Omni light for the background outside the window and another one behind the chairs at the rear of the room. My question is why are the areas circled rendering in black? The finish on the chairs should be the same all over, anybody have any idea what I am doing wrong?

[Kyle]

I think you are losing the sideboad unit in with the wall because of the colour. In my opinion your green looked better as far as visuals go. I would also reconsider the image you place outside the window. Looks a tad too close and a little flat.

I like the composition and your rug and sofas work well. Agree with too green apples.

Will be interesting when you add a light on the tv unit, if that is what you intend to do.

All in all a nice image.

[pwharton]

The tv will not glow in this one, I am working on another scene with a glow coming from the tv. The background is not the final one. I just ran into problems with the sofa that I cannot find the problem or a solution for it.

[pwharton]

I have figured out that because I turned off the mr sky the chair was reflecting black sky. But the reason I turned it off was because I am getting the light burn on the ceiling at the windows. If I turn the sky lights control down the black returns on the seating, if I turn off the reflect quality on the chairs same problem with the black happens. The room is a box with a shell modifier on it so it should not (in my mind) high light the area at the window like that. What am I missing here? How do I strike a balance with the light at the window and the backs of the chair? Why only the certain panels of the chair turn black?

[stefan89]

think the grey material on the coffee table base and the drawer packs is a bit flat maybe needs more texture, the tv screen could do with reflection, is the light patch on the roof caused by a specular level on the material or a omni light that has not got and decay? Its a lot better than what i can do at the moment, am doing something drastically wrong somewhere and i think its my units scale, because i import my objects from soildworks lol, any way keep up the hard work cause i know it can be hard work sometimes to get the results you want!

[Fran]

Does Exposure Control still work with mental ray or is there a physical camera now? Also, having a light source (large area light maybe?) opposite from the window might help to balance the lighting.

[Justin Hunt]

The primary exposure control for mental ray is MR Photographic exposure and works really well. It has two methodes of exposure, EV which is a simple value you dial up and down and mr calculates the rest or Photographic exposure where you can set the shutter speed, F-stop and ISO

 

Coupled with this is control over the curves, colour saturation, white point and Vignetting.

 

Very easy to use, much easier than the old Logarithmic (Which you can still use)

 

A Physical camera in mr would be nice, especially when doing multiple views.

Thanks guys,

 

With all that is going on with jobs and all I've been a little distracted lately. I have not worked on updating this image, in the last few weeks. I have been stuck trying to figured out why the material on the chairs keep rendering black on the faces facing the windows. solve one problem, run into another..
