keys1969 Posted January 13, 2006 Share Posted January 13, 2006 Hi there, This is my first post and want your opinions about my first interior render! Since several years I became interested in computer graphics and specifically in the area of architecture. Browsing the internet I found this great site. I browsed the forums and saw some of the work you guys already done. I was very impressed so I registerd and became a member. I'm working with C4D 8.2 and Advanced Renderer. Below is my first attempt to model an interior. The first problem was the background picture. I placed the garden on a plane and put it in front of the window, pressed render, and... I saw the shadow of the plane on the floor of the room. How can I get this done better? An answer or any other feedback would be very helpful!

alfienoakes Posted January 13, 2006 Share Posted January 13, 2006 Don't know a thing about C4D, but the first thing I notice is the bright sun coming in thru the window, and then the dark external image. Needs to be brightened up some.. Also the shadows on the floor don't look right.. It shows up on the grey chair on the left front of the image.. Also, the picture on the wall needs some shadow around it.. The room needs a bit of "volume" to it.. the lighting is good, but just needs a tweak.. imho..! But nice image for a newbie..

Lhanh29 Posted January 14, 2006 Share Posted January 14, 2006 Good working! I don't know C4D too.But i think The Curtain,sofa were be unreal too much.Maybe you have some problem with lightings.Keep good your work.Just in my opinion.Don't mind if i'm wrong. :) Link to comment Share on other sites More sharing options...
arquiteck09 Posted January 14, 2006 Share Posted January 14, 2006 in 3ds max you have an opcion call output for the bitmaps, it makes the image brighter, maybe in C4D you can find something similar. Link to comment Share on other sites More sharing options...
phil Posted January 14, 2006 Share Posted January 14, 2006 CONCEPT Maybe I'm too used to seeing those sharp funky modern interiors, but it feels like it looks like a mookup-of too many stiles. You have the modern furniture chairs, a kind of post-modern light. I really don't like the lamp (sry). Maybe you could add some built-in spots, MODELLING It feels like the curtains touch the ceeling. Try making them a little smaller. This will generate a little more depth (shadows). Maybe you should add a plint (I mean the border between the floor and walls;how do you call it anyway in english). You could add a negative one. Like a U-typed alu-profile. It gives a sharp edge on the stucco. LIGHTING I agree with alfienoakes about the lighting. You also notice that the corners are really bright referred to the ambiant light. Is your render scanline ? Think so, but not sure. If you wish it to remain scanline use the imagemap, so the lights blends a little more. TEXTURES But you should some work in the textures too. The carpet looks quite flat. The stucco on the wall seems very articulated. I should add a little more glossiness and reduce the bumpmap. The soffa on the other hand requires some bumpingmap and specular. Is it supposed to be canvas, or leather ? I would make the curtains a little more white. This should result in less transparancy (dark curtains have much more see-through while white ones generate more glare). OVERALL It's a good start. Just some tweeking and I'm sure it will come out nicely. Don't be offended by the criticism it's already ok, just doesn't really have the 'wow'-yet. greets, p.

keys1969 Posted January 15, 2006 Author Share Posted January 15, 2006 Thanks for the feedback! Ok, the external image is too dark I'll try to get it more bright. Some shadows/lights don't look real... I placed some omni lights (low strength, no shadow) along the wall with the picture and the wall opposite of that. I realise now that they light not only the wall and ceiling but also the chairs more than I liked to. I removed the omnis and tried to get better lighting with only the direct sunlight. I made the curtains shorter (they no longer touch the ceiling). I've also modelled some "plint" (I'm dutch so I know what you mean ;-). I also made the window larger, I like it better that way. The render is Cinema 4D Radiosity but because of the omnis, the edges were probably well lit so not too many dark areas there. Furthermore, changed the properties of some textures. Tell me what you think of the new render. I didn't have time to set min/max optimally, so there are artifacts visible in the picture but I'm working on that.

STRAT Posted January 15, 2006 Share Posted January 15, 2006 looks much better, but things look like they're floating (ie, the chairs) also, there's horrible gi artifacts in there. you need to seriously jack up some of the radiosity settings.

phil Posted January 15, 2006 Share Posted January 15, 2006 great progress ! I join STRAT about the radiosity settings, but could it be that the walls have a reflection channel. This could also be to the radiosity setting but there are some strange spots on the windowbeam. Personnally I feel your lighting setup has improved, but the shadows look really raytrace-sharp (missing the corona). What troubles me about the lighting is that you don't feel the diffuse lighting. This 'could' be the reason for the floating furniture, like strats points out. Maybe it has something to do with the number of bounces or the cinema4d render-engine (personally use lightwave). May be someone with c4d could help you out here. I really like the feel about the far corner of the room, but the closer you get to the camera the less depth the image has. Anyway it looks much better. Keep it up. greets, p. Link to comment Share on other sites More sharing options...

NOOXY Posted January 16, 2006 Share Posted January 16, 2006 not a bad composition but a couple of factors - the lighting outside don't seem to mach that strong light coming in the room -plants in the room seem a bit too flat, no shadows cast on walls -need to add more quality to your textures seems a bit low in quality anyway not a bad start keep up the work man:D Link to comment Share on other sites More sharing options...
d.sign Posted January 16, 2006 Share Posted January 16, 2006 Nice render, I will just try to help you resolve your background problem. I do ti in Max like this: Just render image without any background, light like I want. Save image as .tga file. When you open .tga file with photoshop 7 you get separated alpha layer - that means places with transparent glass where background should be they are completely transparent. Than open your background image in Photoshop and drag it underneath your render layer. This way you can adjust the levels, coloro balace, position - everthing. If you use photoshop cs you need ro load selection for alpha and copy to new layer... Link to comment Share on other sites More sharing options...
keys1969 Posted January 17, 2006 Author Share Posted January 17, 2006 Thnx for the responses! Hmmm, floating chairs, I checked the model but the chairs are on the floor... it must be the shadow of the mug falling directly over the shadow where the chair hits the floor. I'll change the position of the sun a bit to see if that helps. About radiosity, you're all right but I made the render quite quick so with low radiosity settings. In the future I promise not to do that anymore. The shadow is indeed hard. I put a spotlight out there simulating the sun and used hard shadows. Should I use soft or area shadow? Phil, can you explain a bit more what you mean when you say "you don't feel the diffuse lighting"? What can I do to improve that point? How do I improve the depth of the image do you guys have any suggestion for that and I will try to implement it! Nooxy, the plant indeed looks flat, it just has a green color on it, any suggestions for a texture? Thanx for all your advice so far! With your hints I'm sure I'm going to be able to improve the picture a lot. d.sign, I will try your background solution and see if it works for me too!

keys1969 Posted January 20, 2006 Author Share Posted January 20, 2006 Hi guys, I made some changes: * in order to increase render speed I brought down diffuse depth to 1 and added two fill in omnis with low strength settings. * in order to decrease render artifacts I set the number of stochastic samples to 1000. * I changed the position of the sun light. Now the shadows of the table do not overlap with those of the red front chair. The "floating" of the chair is decreased. * I changed the sunlight shadow in soft * I changed the texture on the plants. Mentioned problems not yet addressed (but also no clue how to solve them ): * shadows of plant on the wall: the plant is standing in the shadow of the wall itself... how should it cast another shadow on the wall? That's it for now, let me know what you think! [ATTACH]10821[/ATTACH] Regards, Jack Link to comment Share on other sites More sharing options...
phil Posted January 20, 2006 Share Posted January 20, 2006 Great progress, It's looking much nicer. About the shadow of the plant, where is it ? I see some colourbleeding on the cieling, but that will were of when you render on in with high stats. Link to comment Share on other sites More sharing options...
Sindala Posted January 21, 2006 Share Posted January 21, 2006 Hi Jack, the progress is looking good, although i dont like the floor texture, it's the standard c4d one right? Have you tried turning the ambient occlusion on, it should make the corners of the walls and ceilings a little darker. succes. Link to comment Share on other sites More sharing options...
keys1969 Posted January 21, 2006 Author Share Posted January 21, 2006 Hi Sindala, Could you tell me some more about "Ambient Occlusion"? I found the plug-in but how do I apply it? Do I have to apply it to the color channel or some other channel. Please explain and I will try to get a better result. Thanx, J. Link to comment Share on other sites More sharing options...
Sindala Posted January 22, 2006 Share Posted January 22, 2006 I dont remember how it was in 8.2 but in 9.5 it's just a rendersetting. Ik hoop dat dat iets helpt. Als het met een plugin moet weet ik het ook niet. Link to comment Share on other sites More sharing options...
keys1969 Posted January 23, 2006 Author Share Posted January 23, 2006 Ok, I've acquired the demo version of 9.5 and indeed there is a ambient occlusion setting in the render settings. I'll give it a try and post an update in this forum (I know I can't save, but I can capture a screen ;-) Thanks for the c&c, Jack Link to comment Share on other sites More sharing options...
keys1969 Posted January 23, 2006 Author Share Posted January 23, 2006 Ok, I changed some material and added spots. I further managed to render with Ambient Occlusion using R9.5 demo. [ATTACH]10873[/ATTACH] Regards, Jack Link to comment Share on other sites More sharing options...
Sindala Posted January 23, 2006 Share Posted January 23, 2006 Hee Jack, that's looking real real good! did you use area shadows? the floor looks much better too, the other one had soo much colors in it. maybe, dare i comment?, there should be a 'gordijn rails' between the curtains. Als je nog eens vragen hebt kan je me altijd mailen, dat zie ik wat sneller. groet, Dick Link to comment Share on other sites More sharing options...
