christophercrocco Posted February 25, 2015 Share Posted February 25, 2015 I am using vray and my image seems to have a hue to it. My background needs to be crisper and my materials need to be better but it is slim finding good free materials. I think my sun, camera or render setting need to be adjusted. This is my first attempt so be gentle lol. So how can I enhance this image? Chris Link to comment Share on other sites More sharing options...
Francisco Penaloza Posted February 25, 2015 Share Posted February 25, 2015 Well you already named most of what's needs to be improved Other than that, materials are a hard part, sometimes you won't find exactly what you need to it is up to you to create it. CGtextures is a great source always. Sun location, try to play a little more with it. Now the whole front of the house seems a little flat because the lack of shadows, maybe your sun is too low that's why everything is soo orange. If you are doing a late day image rendering it would be fine, but your background does not match your lighting now. Try to eliminate sharp edges, they are very noticeable all over your house, and mostly on the roof, check photo of shingle roof and you'll see you need to model more part still. I think you can also push your camera a little back to give more air to your shot, now the house feels very tight. also try to fill the surrounding of your house with some elements such 3D trees or planes with tree, so your glass get better reflections. You could also fake reflections in post, but not there is non and that does not help your image. good job Link to comment Share on other sites More sharing options...
christophercrocco Posted February 26, 2015 Author Share Posted February 26, 2015 Why should sharp edges be kept to a minimum? Im using a spherical sky background, why doesnt that at least appear in my windows? Link to comment Share on other sites More sharing options...
Francisco Penaloza Posted February 26, 2015 Share Posted February 26, 2015 Well in real life is very strange to have a perfect straight 90 degree edges,mostly if you are working with wood, there are sharp edges but even those they have a little radius at the end, or chanfer. All those perfect corner, tell your eye that it is a "fake" or computer generated image. Also you roof seems to be on one mesh, with different textures for shingles and side wood. It would make it more realistic if you separate the face of the roof shingle and give some thickness. The wall shingles corner also show perfect in your house, when in reality there will be some sort of overlap of shingles in the corners. Google some photos of similar houses and look in all those details. If you want something that look real, it is a safe bet to model everything as it should be in real life and no use cheats, because they will look like cheats. It is also true that we always have to deal with how much time we can invest in modeling and rendering but if you are doing this for yourself to learn it is a good idea to go as far as you can. So you eye get trained to distinguish what is important and what really matters in the image to make it looks better. Your sky may not be giving much reflections to your glass, maybe because the bright intensity and the angle that reflect the glass.

Ernest Burden III Posted February 27, 2015 Share Posted February 27, 2015 Well you already named most of what's needs to be improved Yes, so do those things. Go backwards and build from a good base. Do a clay render to get the lighting the way you want. Then add one material at a time to make it the way you want. Link to comment Share on other sites More sharing options...
deborahkincannon Posted February 27, 2015 Share Posted February 27, 2015 I am just starting out and trying to learn as much as possible. I love 3 D drafting and design. There aren't a lot of opportunities in my area. Link to comment Share on other sites More sharing options...
frog_a_lot Posted February 27, 2015 Share Posted February 27, 2015 If you only use free materials then you aren't going to improve.. you need to learn to make your own materials. It is not terribly hard to make basic materials that will be a hundred times better than random free ones you download and just slap onto an object. Start with a straight gray/clay render to get your lighting right, then just go one material at a time.. To often you see people just download a model, download some materials and then wonder why their images suck.. its the equivalent of trying to make a artistic painting by cutting out pictures from magazines and sticking them to a canvas.

frog_a_lot Posted March 2, 2015 Share Posted March 2, 2015 what does everyone mean by gray/clay rendering? Video or tutorial on this? It is simply giving everything a straight gray material.. no texture, no colour etc.. some people use a lighter gray some use a darker gray, that's personal preference. Materials and textures affect lights in different ways, so it is best to start off by lighting your scene with none of that stuff. Link to comment Share on other sites More sharing options...
