willofmaine Posted December 21, 2012 Share Posted December 21, 2012 It looks to me like there's some kind of haze on the camera lens in the original photo; is that what you're trying to simulate? The rendering looks better than the original to me, for what it's worth... Quote Link to comment
barkest Posted December 26, 2012 Share Posted December 26, 2012 With area lights I find it best to make sure that the brightness is at least 5000 (default is 1000) and also make sure they are not right next to a surface (such as your ceiling) as it will become blotchy. Quote Link to comment
lchen Posted December 27, 2012 Author Share Posted December 27, 2012 thanks a lot barkest Quote Link to comment
lchen Posted December 27, 2012 Author Share Posted December 27, 2012 there are about thousand lamps in the model. the speed of render is very slow slow do you have any advise? Quote Link to comment
barkest Posted December 27, 2012 Share Posted December 27, 2012 Add a camera and create a viewport. In the sheet layer select the viewport and make sure the visualisation palette is open. Turn off the lights you do not need for that particular camera shot via the visualisation palette and just render the lights 'in shot' In the OIP click lighting options (this will show with the viewport selected) and push the ambient down (or turn it off maybe) and decide on the indirect lighting (probably none in your case). I believe in 2013 (I don't have this) that you can render a viewport and then return to the design layer to carry on working whilst it renders and it shows when it is finished via the navigation palette (others can confirm this). maybe others have a better or different idea to this but I would not be doing a render of the whole scene as a 1000 area lights (seems very high to me btw) is going to hurt. Also I have no idea what your render settings are so its pretty much guesswork (I would play around with custom) and also I have no idea what textures you have set up etc. Quote Link to comment
michaelk Posted December 27, 2012 Share Posted December 27, 2012 It might also help to make lights into symbols. Use class assignments to "turn of" lamps not in view. Perhaps changing the profile of the lamps from a circle to an octagon or hexadecagon... Curved surfaces take longer to render and in this case the curve may not be visible... mk Quote Link to comment
John Meunier Posted December 27, 2012 Share Posted December 27, 2012 I find that area lights take a longer time to render than using many spot lights or point lights. [img:left]http://techboard.vectorworks.net/ubbthreads.php?ubb=download&Number=8454&filename=Light.jpg[/img] Quote Link to comment
