Tommy L Posted January 27, 2007 Share Posted January 27, 2007 This is a frame from a night animation im working on. Time is limited so i have to keep render times to minimum. Currently its 4 mins (vray 1.46/max8). Anyone have any tips on lighting up the glass part without raising rendertimes too much? Link to comment Share on other sites More sharing options...
Tommy L Posted January 28, 2007 Author Share Posted January 28, 2007 Another shot. Render time up to 6.5 mins a frame. Anyone know if its possible to optimize lens effects? They seem to take a long time for a simple operation. Comments/advice welcome (but I do realize its Saturday night, so i wont hold my breath!)

F J Posted January 28, 2007 Share Posted January 28, 2007 wow! it looks kinky cant wait to see the final anime.. i hope those trees arent like those that stare at u as u move along good job, keep it up.. Link to comment Share on other sites More sharing options...
Tommy L Posted January 28, 2007 Author Share Posted January 28, 2007 the trees are modelled, not RPC, so they look pretty sweet in animation. Link to comment Share on other sites More sharing options...
neil poppleton Posted January 28, 2007 Share Posted January 28, 2007 Building above ground floor looks great Tom, although a lttle dark, with the lightish sky background i would expect the building overall to be lighter. Have you tried bitmaps for lighting apartments up ? mix all the glass on several random layers and have several random colours/lighting for each glass pane or apartment... just a thought......

saurus Posted January 28, 2007 Share Posted January 28, 2007 Very intrusting project Just a thug Make your lights half its intensity and rise your camera level to the to show the hole building Keep up the good work Link to comment Share on other sites More sharing options...
Tommy L Posted January 28, 2007 Author Share Posted January 28, 2007 Latest attached, render time 8mins. Link to comment Share on other sites More sharing options...
saurus Posted January 28, 2007 Share Posted January 28, 2007 Can you show the whole mass of the building? Because you're showing the lower part of the building. Link to comment Share on other sites More sharing options...
Tommy L Posted January 28, 2007 Author Share Posted January 28, 2007 Well these are just frames from the animation, so you will see the whole building in some parts and not in others. Ill post the frame rendering at the moment so you can see the whole building Link to comment Share on other sites More sharing options...

Justin Hunt Posted January 29, 2007 Share Posted January 29, 2007 The blue tinted amient light thats on the surrounding buildings would make a nice fill for the big building. JHV Link to comment Share on other sites More sharing options...
Guest sachinwalvekar Posted January 29, 2007 Share Posted January 29, 2007 hi, I have an animation project in hand & currently using p4, 2.3 ghz with 1 GB RAM. I am planning to upgrade. I think the render time that u r gettings are good. I would be grateful if u can share ur system configration. Thanks & regards, sachin. Link to comment Share on other sites More sharing options...
Tommy L Posted January 29, 2007 Author Share Posted January 29, 2007 sachin, i am running a dual dual xeon, not sure what spec, and 2 gig of ram. That said, my laptop is about the same speed for rendering and thats a duo 2 core dell with 2 gigs of ram (Inspiron E1705(?)). With only 2 processors it keeps up with the 4 processor xeon. Check out the technical forum tho, there are some very knowledgable people on there. I dont know much about hardware, just forcing work out of whats available. Justi, Youre right. The only washes at the moment are orange fill lights around the lower part of the building. The blueness comes from the map in the environment slot, but its a bit lost on the main building. Ill beef it up with some ambient only omnis. Cheers, Tom Link to comment Share on other sites More sharing options...

FlytE Posted January 29, 2007 Share Posted January 29, 2007 I find the screen layer style in photoshop is excellent for brightening night windows. Thats because anything when its on screen, anything thats black will not brighten up, but anything that is light tends to brighten up more - hence why it works well for night shots. Im sure you can apply the layer effect in premiere etc Link to comment Share on other sites More sharing options...
Tommy L Posted January 29, 2007 Author Share Posted January 29, 2007 Yes indeed the screen layer is handy, but difficult to apply in an animation when the footage is not rendered in seperate passes. This needs to be re-rendered, so ill run an id pass for the glass. Thanks, i hadnt really considered many post options. Link to comment Share on other sites More sharing options...
3D_IC Posted January 30, 2007 Share Posted January 30, 2007 Looking sweet Tom. Maybe render your lens effects out seperately on comp in afterwards. They add so much to the scene and it would be a shame to lose them Link to comment Share on other sites More sharing options...
Tommy L Posted February 8, 2007 Author Share Posted February 8, 2007 Well im back on this project after being on holiday, changed the lighting a bit and the render time is up to 18 minutes a frame! bummer. Link to comment Share on other sites More sharing options...
alfienoakes Posted February 9, 2007 Share Posted February 9, 2007 Night time images I find very tricky.. Looks good though. How many lights do you have in this one, and what type did you mainly use..? Link to comment Share on other sites More sharing options...
Claudio Branch Posted February 9, 2007 Share Posted February 9, 2007 Very nice...will you be posting a link to the final animation? Are those Speedtrees? I've been using SpeedTrees, but my render times are so looooong... Link to comment Share on other sites More sharing options...
FlytE Posted February 9, 2007 Share Posted February 9, 2007 A useful tip (which again may work well for a night animation) is to turn off generate GI (and also generate/recieve caustics) in the properties of as much geometry as you can, but especially for trees, cars, people, lampposts etc. Try it and see how much GI you can turn off before you get a noticable change in quality. On that subject, instead of having bright lights lighting your rooms, you could have weaker lights in rooms that have walls with 'recieve GI' set to like 3.0. This would hopefully brighten up your rooms without having rely on heavier calculations of lights with bigger multipliers.... worth a try? Link to comment Share on other sites More sharing options...
Tommy L Posted February 9, 2007 Author Share Posted February 9, 2007 Alfie: This scene has 781 lights and 1.3million faces. They are mainly target lights externally (for streetlights) omnis for 'ambient only fills. Internally; omnis only. All lights are attenuated and only light specific elements. All external lights have shadows on. internal lights only have shadows on if lighting through glass so they cast a shadow of the window frames. Claudio: I modelled the trees myself. Each has about 600 faces but is quite heavy due to the transparency maps. FlytE: Many thanks, I'd totally forgotten the turn off the generate GI option to control rendertimes. I was running out of optimizing options! I will try to post a link to the finished animation, not something ive done before. Wont be finished for a while. Just got some design changes thru and i need to run the cars in a seperate file too. Link to comment Share on other sites More sharing options...
Claudio Branch Posted February 9, 2007 Share Posted February 9, 2007 Goodness man! You did a really nice job on them. I have thought about modeling up some tree's myself, but I wanted to give myself more time with SpeedTree. I just haven't had great luck with it. I saw a really cool demonstration by a mental ray programmer of a "geometry shader" that could simulate a tree canopy rather convincingly. I would probably go about it using a particle system and opacity maps. Link to comment Share on other sites More sharing options...
Tommy L Posted February 9, 2007 Author Share Posted February 9, 2007 It was pretty easy really. I made the maps first, creating lower, mid-height and top parts of a tree that would be arrayed in a circle (in plan) then pushed and pulled vertices until they looked a bit more ramdom, then modelled the trunk. Do you want me to post the maps and stuff? Link to comment Share on other sites More sharing options...
Claudio Branch Posted February 9, 2007 Share Posted February 9, 2007 If you don't mind putting up something, I will use it and surely there are others who could benefit as well. Thanks. Link to comment Share on other sites More sharing options...
