    My bad Sevrin, you are right. Link is below. I got the motion file from MMD so obviously the video source will usually be MMD also. I could not find a live real person version of the song.

    Here's my 2.5-cents' worth (and it doesn't go nearly as far these days as it once did).

    1. That "set" (if it even is one; stay tuned) has massive upstairs winddows surrounding it, from the available views, which would allow in a LOT of light from an external HDRI, but ...
    2. It doesn't look like that character is actually lit by the surrounding "set" (stay tuned) or environment, and ...
    3. I think the "set" (stay tuned) may well have been rendered separtely, then the same camera(s) was used with the exact same motions to render the girl separately (green-screened or just no background to have transparency), then those renders, plus the swirling particles (probably stock film footage), were all overlaid in movie editing software—OR...
    4. The "set" itself is simply a big HDRI, like the "Movie Maker Iray" ones done by Dreamlight, so she is being lit by it, plus all kind of other lighting as needed or wanted.

    The little bit (very little) of shadow/reflection she is throwing on the "floor" could very easily be accomplished with either methods above.

    So you may be going about it from the other end of the telescope.

    I guess by torch, Imean the old style retro night club act. You are right this is a bit more peppy, but I don't know if I would think of it as JPOP.  in the MMD vein, they do a lot of take offs on the old styling, Like Boooo!! for example, it has kind of a "Big Band" sound track. Also if you can find it there is the Koi Song with a definate 1950's flair. This is why I love MMD,there are motions available for almost any genre you can imagine from sports to dance, martial arts, hip hop, rock and roll, ball room................... and of course they can all be converted into a DAZ usable format. Anyway I do have many different moods of motions, I don't know what type of anims you like doing, if you are generally into animation at all, but let me know if there is a particular genre you would like to try. Not all of them are over 40000 frames.

    Rats, I was hoping you meant the Tainaka Sachi song.

    Which song do you mean Gordig? Did she do one called Lipstick?

    Mavante, the "Set" in the video is not what we are talking about for lighting here. The video was just a reference for the song that goes with the BVH that I posted. I was originally talking about different lighting ideas for a night club scene and shared the BVH because it was the animation for the scene I was working on.

    Hey Gordig if you can find an MMD motion for that song I can convert it to BVH for you! I did a search but turned up no MMD.

    Oh. Oops. Sorry. I guess I dropped my compass and wandered astray because I can't find anywhere any specs on the stage set you a-r-e trying to light that you cobbled together. How many walls does it have? Is it fully enclosed? Does it have to have a ceiling? Could any of my points 1 through 4 in my post above apply anyway? I think they very well could apply, but maybe not.

    Did you ever look at the Parmy video I linked to on page one? You didn't say, but it directly addresses the issue you put in your first post about "maybe some abient light but still have the sharp spotlght effects." Or did you look at the info on stage lighting angles I linked to?

    I think it's very fortunate that you have someone like Sevrin trying to help you, given his background in stagecraft. I wouldn't care to try to match it, but I did spend six years on the other side of the lights as a traveling music performer, then later was the director of a small live theater in L.A. for several years, including sometimes single handing to run the light booth. I'm just trying to pitch in with any tips I think might help you achieve what you're tryint to achieve.

    I'll go find my compass and look for the exit ...

    So I made an HDRI of Charlie's Nightclub and rendered a couple of seconds.  The set comes with stage lights, and I removed them from the set before making the HDRI and added them back to render the animation, so those effects are "live".  Here's one frame in HD and a link to the 360p animation

    LOL........Mavante, your input as well as Sevrin's is extremely welcome and I would not say you are without a compass at all. Yes, your points are very helpful. Thank you. You are right though I am eating up all the advice that Sevrin is offering. To that point Sevrin this new render really capyures a club stage ambience.

    Thank you, Thank you Sevrin!!! OK so since I am not well versed in HDRI's The walls, catwalk ceilinf light fixtures even the bar counter in the back are all part of the HDRI and the God Rays werre added back in for the render? So to create an HDRI you can't use something like Gimp can you?  Oh, so also did you apply emissives to the the catwalk and light disks prior to creating the HDRI?

    I'm also dying to know where you got the character. I think I have purchased almost every Asian character they have here.

    By the way Mavante, The set I put together only has the stage components but I am planning on adding tables and a few select walls, vinette style becaus the main focus will be the stage. Trying to acheive like an old style Jazz Club setting. Trying to figure out how to get some of Sevrins fantastic lighting effects into that, and maintain a sultry feel, like the Jessica Rabbit bar scene in Roger Rabbit. But I mean look at the atmosphere in Sevrin's last render...............................Nice!!!!! The biggest problem is I don't think I have the right tools to make HDRI's or do any post effects. So it is pretty much DAZ built in light for me and a render as is approach. I'm learning a lot here though.

    Thank you again for

    So, the HDRI.  That's the easy part, and you have the tools.  It might take one or two tries to get exactly what you need, but it's not complicated at all.  Once you get a good result, you will know how to do it for all your scenes, and it's especially good for animations.  You can do all kinds of tricks with HDRIs.

    There are a couple of ways to make them.  The basic stuff about the camera, and one method of rendering is very well described in this video by Thundorn.  What I do is similar, but I use the Advanced > Canvas in Iray render settings to render a beauty canvas which gives use an EXR image, in this case 8k x 4k and you convert that to HDR.  EXR and HDR images are both 32 bit, and HDRs are what you need.  The Nightclub is a nice set and already has all those emissive lights, and all I did with this set is remove the 6 stage lights I wanted to put back in the live render.  Rendering a big image with good quality is slow, but setting up the render only took a few minutes.  You choose where to put the camera, zero all rotations and set it to spherical lens distortion.  In tone mapping set burn highlights to 1 and crush blacks to 0.  I haven't used The Gimp for a while, but here's a tutorial that will help if you choose Thundorn's method.  The Gimp can import EXR images and export HDR images, though, so I'd go that way, since you only need to render once.

    Once the HDR was made, I just used changed my HDRI in Daz, got rid of the tables and rendered.  I also changed the outfit for something more dressy.  Ren Yao is a model by DaYin at CGBytes.  He has a bunch of nice affordable characters, but this is the first one I bought from this vendor.  I put an Altern8 skin on her though.  I noticed a seam on the legs after I did the previous renders, so I will have to see what happened there.

    Oh, and since the scene was heavier because of the volumetric spots with the gobos, I increased render time to 25 seconds a frame.

    I don't know if I will finish this, but it was interesting to experiment with.   If you can find the animations for Namie Amuro's Hide & Seek, I might just render a full clip.  It's an older song though, so there might not be anything out there.

    I don’t actually care, to be honest. I only barely know what MMD even is, and it’s not something I’m in a hurry to get involved in. I just really like that song, and Tainaka Sachi generally.

    Here's the whole thing, sort of, at one frame per second, just to show the rest of the scene.

    Sevrin, Thank you for all your support! You really giving me a feast of information that I can finally get DAZ to work for me. You got me really wanting to explore the possibilities with HDRI's

    So I am wondering how it would be possible to incorporate animated lights, I know that we have animated texture products but can it work the same way as an HDRI.

    Take a look at this video, and look at all of the animated lights which can be done with animated textures or even the script from Mcasual that allows key framing of any surface. I have these stage models from MMD which I can export as an OBJ. and import into DAZ. I could even set up all the flashy animated lights with key frames but is it possible to turn that into an HDRI to save on rendering time?

    An HDR image is static. You would have to change it for each blink.

  • kwanniekwannie Posts: 870

    I forgot to mention,I did a search for  Namie Amuro's Hide & Seek in an MMD format, but no such luck. If you do want a particular song, just search for the title and add MMD motion dl to your search and you may be able to find some songs you like. If so let me know where to download the motion and I can convert it for you. Granted most are Jpop or Kpop but there are many classic American songs to. Deviant Art is chock full of people who created motions.

    I am, too. Sevrin is an ace, and if he published a video tutorial on all his steps and tricks to create that HDRI, I'd be lined up, credit card in hand! Can't wait to see what you come up with.
