jason1025 Posted November 12, 2009 Share Posted November 12, 2009 Hey folks How would you create a rail of light? Like say a florescent light bulb? Quote Link to comment Share on other sites More sharing options...
agep Posted November 12, 2009 Share Posted November 12, 2009 Like a fluorescent tube? How about animate the light from one end to the other end within a frame and render with multipass? Quote Link to comment Share on other sites More sharing options...
agep Posted November 12, 2009 Share Posted November 12, 2009 Hmm, that didn't work.. I have forgotten how u did this trick Quote Link to comment Share on other sites More sharing options...
agep Posted November 12, 2009 Share Posted November 12, 2009 Ah, yeah. create an action, animate the light within eg 16 frames. put the action on the model in the chor and set the cycle lenght to 1 frame. I'll do a test and see Quote Link to comment Share on other sites More sharing options...
Paul Forwood Posted November 12, 2009 Share Posted November 12, 2009 Interesting solution. You might be able to do that by just selecting all of the keys in the action and then dragging the right end of the selection bar to the left to scale it, forcing keys onto subframes. Same thing, different approach. Quote Link to comment Share on other sites More sharing options...

jason1025 Posted November 12, 2009 Author Share Posted November 12, 2009 Thanks for the RND. Although this is a great solution. Do you think we should make a feature request to be able add in addition to regular lights, neon or florescent style light bulbs? Quote Link to comment Share on other sites More sharing options...
jason1025 Posted November 12, 2009 Author Share Posted November 12, 2009 Agep In your example does this work for actual animation or just stills? Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted November 12, 2009 Hash Fellow Share Posted November 12, 2009 Do you think we should make a feature request to be able add in addition to regular lights, neon or florescent style light bulbs? agep's solution is the way A:M supports that need. "Any spline can be a light" True area lights are time consuming to render and probably wouldn't be any faster than the multipass solution.

Yes but I don't see the solution for animation just still frame. Remember we are using "Animation Master" Quote Link to comment Share on other sites More sharing options...
jason1025 Posted November 12, 2009 Author Share Posted November 12, 2009 I also dont understand how you can turn a spline or mesh into a light, please explain Quote Link to comment Share on other sites More sharing options...
Hash Fellow robcat2075 Posted November 12, 2009 Hash Fellow Share Posted November 12, 2009 you path constrain a light to a spline you set its ease to traverse that spline in less than one frame and repeat that every frame multipass renders the light at all the different points of the spline creating the effect of a non-point light. The same technique is used for spinning light rigs and works fine for animation. This is really a light "Array" but with the great convenience of not having to create numerous separate lights and the option to do quick tests with fewer passes. Here's a page from a book in which they discuss true area lights and their downside even in a vastly more expensive app. Quote Link to comment Share on other sites More sharing options...
jason1025 Posted November 12, 2009 Author Share Posted November 12, 2009 Thanks Robert. I dont suppose you want to do a quick video tutorial. The concept of steps in a frame is hard for me to grasp. Maybe I need to see the process. Quote Link to comment Share on other sites More sharing options...
NancyGormezano Posted November 12, 2009 Share Posted November 12, 2009 As Stian said: create an action, animate the light within eg 16 frames. put the action on the model in the chor and set the cycle lenght to 1 frame. Thats how you get the light to travel a path in 1 frame. Quote Link to comment Share on other sites More sharing options...
HomeSlice Posted November 13, 2009 Share Posted November 13, 2009 Thanks Robert. I dont suppose you want to do a quick video tutorial. The concept of steps in a frame is hard for me to grasp. Maybe I need to see the process. Just follow agep's instructions. Set the Action to "Repeat" however many times necessary for the length of your chor.

Hash Fellow robcat2075 Posted November 13, 2009 Hash Fellow Share Posted November 13, 2009 Here's the non-action method: After You got your light constrained to a path: then set the ease to 0% at 0 seconds 100% at 1 second 100% at 5 seconds grab it and squish it all down to 1 frame. Use CP settings to make the last one exactly at frame 1. Then select it all again and >Curve>PostExtrap Method>repeat render with multipass and motion blur set to 20% the guide spline has been set to render as line to make it visible. 5 passes shows obvious stepping but gives a quick approximation 36 passes looks smooth 81 passes is only slightly different than 36 Quote Link to comment Share on other sites More sharing options...

photoman Posted November 13, 2009 Share Posted November 13, 2009 OK here is my try. Ringlight_EXAMPLE.mov 16pass for 30 frames. The light rig is just a ring with a bulb light moving around it. I set the cycle length of the action to .1 and to repeat 300 times (1:00 long). I rendered with 100 % motion blur though... didnt work without that on...
