JeremyRamsay Posted January 14, 2014 Share Posted January 14, 2014 Hi, I'm trying to load an .avi of an LED display onto a Vray 1.5 material for a nightclub created in Max 2010, (I know I should upgrade but not possible yet), can anyone advise please as I can't find the procedure, the .avi has to be self illuminated as well. Thanks if you can. Oh, and if anyone can advise on how to make this .avi move around the room as well I'd also appreciate it. Imaging a room full of LED's and the graphic traveling across the floor, walls and ceiling. Thanks. Link to comment Share on other sites More sharing options...
Scott Schroeder Posted January 14, 2014 Share Posted January 14, 2014 Apply the avi as a vray light material? You should be able to load the avi into the diffuse slot, assuming max supports the codec. If not, you'll need to render out each frame as an image (say from After Effects) and load those images into an IFL file. To make the image move, simple use a 2nd (or 3rd) UV channel, set the movie to be that UV channel number, then animate that UV modifier across your surface.

JeremyRamsay Posted January 14, 2014 Author Share Posted January 14, 2014 Thanks for the quick reply, I've tried loading through VrayLight material through the bitmap channel but it won't load. I'll try the After Effects route. Are you saying once I have the IFL file, it should load through the bitmap channel into a Vray Light mat? As for making effect move, I'm afraid you lost me but thanks for the advice. Link to comment Share on other sites More sharing options...
Scott Schroeder Posted January 14, 2014 Share Posted January 14, 2014 If the avi won't load, then max probably won't support the codec. Once you get all of the individual frames from after effects, inside max you'll want to select the first image in the sequence, then look at the bottom of the choose image window and you'll see a checkbox for "sequence", check that and max will create the IFL file for you. You'll want your moving image on a UVW channel separate from your wall/floor texture images. For example, if you have a brick wall your brick texture coordinates would be on channel 1. You wouldn't want your movie on channel 1 as if you animate the UVW map modifier, you'll move your bricks as well. You want to move the movie file to channel 2 or higher so you can move it around and keep your base texture image still. Link to comment Share on other sites More sharing options...

Stephen Thomas Posted January 15, 2014 Share Posted January 15, 2014 Also if your led displays are behind glass you can do this by placing the light material into a vray blend material, then add a layer with reflection and black diffuse as a top coat. This will also help to retain the sense of 3-dimensionality in the room, otherwise with all surfaces being a light material you will lose any lighting and shading.

JeremyRamsay Posted January 15, 2014 Author Share Posted January 15, 2014 Thanks chaps, the movie of the LED display I'm considering using is only available in .avi format, so there are no individual frames available to create an .IFL file, or am I missing a trick in After Effects?

Stephen Thomas Posted January 15, 2014 Share Posted January 15, 2014 The IFL is created by 3ds max automatically when you load in an image sequence. Just output a jpeg sequence from After Effects and you're good to go. Link to comment Share on other sites More sharing options...
JeremyRamsay Posted January 15, 2014 Author Share Posted January 15, 2014 Right, got the .ifl and loaded it into a Vray light material, thank god for Youtube tuts, thanks Stephen. The last part, do you know how I could contain this effect to different parts of my nightclub. Think of a torch beam moving across a wall, then the ceiling. The effect needs to be localized. Problem is, once that LED material has been assigned to an object, say the ballustrade, that material will effect the balustrade all of the time and not just for a second or two. The effect need to move from the balustrade to a wall then to the ceiling. How do I get it off the balustrade once it's on? Link to comment Share on other sites More sharing options...
Nic H Posted January 15, 2014 Share Posted January 15, 2014 sounds like you may actually may want to use a projector light. or are all the surfaces LED? what can also sell a LED look is having a fine dot pattern in the blend amount slot of your blend material - this gives it a bit of texture and looks a little like pixels. the gloss base layer that stephen suggests will also help a lot.

JeremyRamsay Posted January 15, 2014 Author Share Posted January 15, 2014 Yeah, I was considering a projector light though I was trying to get it to look spot on. If you can be bothered, type in Smack Lemmington Spa into YouTube. 'Smack' is the name of a club by the way. There's a bar that has the effect I'm looking for.

Crazy Homeless Guy Posted January 16, 2014 Share Posted January 16, 2014 I would tackle this with an custom built animated HDR sequence using Aftereffects where the LED lights in the HDR files are intense enough to generate a glow for the surrounding geometry. The intensity should also be strong enough to generate glare in post. Then apply that sequence in the diffuse slot of a Vray material and map it to the walls. The idea is not to illuminate the room this way, but to generate a convincing effect. It will look quite elegant if done right. Link to comment Share on other sites More sharing options...
JeremyRamsay Posted January 16, 2014 Author Share Posted January 16, 2014 Thanks for a solution Travis but I feel that's a little beyond me. I simply don't have the time to learn the process then put it into practice before my deadline's up. It would be quite a thing to see though.
