Title says it all. Keyword here is “Simple” :). Will appreciate C & C. I’ve spent way too much time on this project, so I won’t be making anymore changes.
This has been a very good exercise for me in texturing with uv mapping and also bumpmapping. I figured out a quick and easy way to bumpmap is to use the same texture as the bumpmap with the RGB disabled.
Had a lot of trouble with the UV mapping in Lux, but the good people at the LuxRender forums helped me out with it. Here’re the renders in BI, Lux and Yafa in the order they were done. This is by no means an exhaustive test and it is not right to judge the engines based on these images. I include them all here because I feel each of them is interesting in its own way:
Yafaray, 3 light sources, Unsure about the weird spots on the painting frame, Photon Mapping, Render time: 7 hours on single core (effective 3.5 hours on dual core?)
By no means am I an interior decorator, but am willing to take crits to learn :).
Btw, on the table in the middle, the 3 books are blender mags if you look closely :).
Models look good. I like how you used the different renderers. To make it fair though should turn on AO (multiply) in the BI render. I’m also surprised by the grain in the Lux render (I love Lux, does an amazing job, 40 hours should have been enough easy). Your best result hands down is with Yaffa though. No crits on that (with maybe exception the spec on the picture frame), very nice render. Out of curiosity did you use 2.49b or 2.5?
@Quandtum: My initial thought was to do it in BI 2.55 completely to save time. So, I started modeling it in 2.55 and did the first render. But I was rather disappointed with the result and also quite confused with the various settings in BI. Also, on my laptop, if I enabled global lighting and some of the other options, the rendering slowed down to a crawl and that bummed me out. Can’t remember if I used AO or not, but I played around with quite a few and this was the only complete attempt I made with BI. So I decided to go with tried and tested LuxRender to get realistic rendering and loaded it up in 2.49b. I also wanted the ability to play with gains in a single render and change it to a night/late evening scene. In Lux I could identify mistakes within the first few minutes itself and the long wait for the complete render was worth the flexibility it offered. But after having it run continuously for 2-3 days, I gave it up and picked up Yafaray.
@Ace Dragon: I never had Lux take this long to get a decently noisefree render. I think it’s because of my obsessive bumpmapping, the sunlight and the 3 mesh lights (2 wall lights and the lamp). Here’re the settings in Lux:
@-[Killer]-: Like I said, I got carried away with bumpmapping :). I figured nothing in real life is ever actually smooth and since I’m applying textures, might as well give them a few bumps. Couch, carpet, blinders, curtain holder, lamp table, window frame are all bumpmapped.
But, the Yafaray render doesn’t have a hardwood floor. The settings between Yafa and Lux are almost identical (BI is an earlier version, so it’s significantly different). I guess it’s not very clear, but the floor is a carpet with bumpmap.
Btw, everything is done on my $500 laptop with AMD Athlon X2 and 3gig ram :). As for the weird specs on the painting frame, I looked in the file and couldn’t find anything to cause that. I’ll just leave it as it is.
Fine renders there. But you haven’t done justice to the BI render. There’s this awesome bathroom interior render done in BI. You could do far better than that, though it’d take some time.
I believe the lighting setup doesn’t do justice to your models though. I really can’t make out the sofa details in the renders.
@agentmilo: I completely agree. I saw the bathroom render a couple of days ago and it blew me away. But I’m a lot more familiar with Lux and Yafa and I can view the results much more quickly. I do intend to gain some familiarity with BI, but it will take some time since the options are quite confusing. Maybe watch a tutorial or two would help.
I believe the lighting setup doesn’t do justice to your models though. I really can’t make out the sofa details in the renders.
Hmm, I see your point. Not sure how to fix that though, maybe a low intensity spot or area light positioned to the right of the camera and outside the scene?
Good point. But again, not sure how to fix it. I did have a plane surface initially with a texture of fauna, and it worked fine in Blender Internal with a lamp outside the window (You can see it in the first image), but I couldn’t figure out how to do the same with the light coming through the window in Lux and Yafa. I did toy with the idea of opening another window to the right of the scene so that I can have sunlight fall on the plane and show the image, but then the effect of the light rays partially obstructed by the blinders wouldn’t have been possible.
Any suggestions to lose the darkness will be appreciated. I don’t think I’ll be going back to edit this project, but it will be very helpful for my next scene.
In LuxRender you haven’t enabled the sky component, that’s why the outside is black. Have you added a portal in front of the window to guide the light through? If not you should really do, it will greatly speed up the render.
Also check your materials, the bump value in LuxRender is the height of the bumps in meters, the specular color of glossy materials should also probably be below 0.2 to be realistic (looks higher on the table).
Ah thanks! I didn’t enable the sky component. I didn’t put a portal either. I hope that fixes the black region outside the window.
Yes, the exponent on the table was at 65. I reduced it to 1.2.
Thanks for your input. I just kicked off a render in Lux after incorporating your suggestions. I’ll post back with the image in a few days time after the rendering completes.
yafaray render looks better…
i think the light on the floor is little too much… also add some background image… it is black now.
that cone thing of the lamps looks flat(probably a different color will do)…also light(lamp) is not reaching the soffa much…
other than that scene looks good
Hey, welcome to the forum. I’m a noob myself, started 3d modeling about 4 months ago.
I would strongly recommend not coming to a conclusive decision about the quality of the rendering engines based on these images. It is not an exhaustive test and each engine has its merits and demerits. Having said that, yes the quality of the image is greatly affected by the engine. Between the Yafaray and Luxrender images, almost everything is identical. But the Blender Internal was done much earlier than those and hence, is a little different.
Thanks Sinosh. Do you know how we can do that with the the light entering in from the window?
