    Playing around with Unity

    I've been fooling around with Unity again, off and on over the past week, and here's what I managed to come up with using the Indie/free version and Vray; an old elementary school classroom model. My coding skills are rusty at best, but I'm hoping to get in more interactivity, possible room layout variations and an interface.

    I'd like to have access to some of the Unity Pro features but I'm not sure it's worth it at this point.

    31.64MB

    I've also installed Shiva3D but I haven't made it past the interface or exporting to Collada; any opinions on Shiva3D?

    Sweet! Unity has some cool capabilities/potential. I've taking a look at some of the tutorials over at 3dbuzz.com they're starting a tutorial on creating an MMO game. Great how the programming technology is becoming 'higher level' and more accessible.
    Nice example. Bit big... From a user-friendliness point of view i think it would be good to have a pallete of swatches as well as the slider. I was trying to get a yellow colour for brick, but couldn't quite get there with red and green.
    What method did you use to bake maps?

      I'm working on having each editable surface highlighted when moused over, and an editor window fade in when clicked. I'd like to use the HSV color space for the sliders, but I'm still working on getting that code to work.

      I've been using the RTTGroup plugin to do my lightmaps. They looked like crap at first, washed out, until it dawned on me I needed to change the Color Mapping in Vray.

      I definitely need to optimize the model and lightmaps; 76MB is too much for one room.

        Can you post some links to the stuff you are talking about?

          Here's the link to RTTGroup. I'm using it with Max Design 2009 and I'm not sure if the creator plans to update it for Max 2011.

          What other links did you have in mind?

          Most of the scripts I'm working on are either a mess or just basic frameworks and I've already saved over the old lightmaps.

          Using Linear multiply for the color mapping ended up with burnt out areas in the lightmap; switching to HSV exponential improved things. It helped to RTFM.

            Been using unity for a while myself, i'm finding it quite awesome, Couldn't view your mediafire link due to works proxy restrictions though

            I've got the pro version, and its pretty nice, the main advantage for us would be the built in baking, but its hard to beat baking lightmaps with vray once you get the importing/building of the materials automated. there are a lot of workflow 'kinks' that need to be worked out to be really useful for architecture, but someone with some coding or determination can build up some nice work pretty quickly.

              Here are some links to some links to some of the 3d Buzz Unity tutorials http://forum.unity3d.com/threads/370...nload-them-now!
              I haven't watched these yet, but i like the informal style on their videos. I learnt character modelling with their Alien modelling tutorial and the poly modelling techniques have helped me a lot with furniture modelling.
              I like the informal style of their training videos.

              ...and some more info on 3d buzz training and MMO they're developing.

                Yeah, fine for a disc, but a bit on the big size for web. If the camera is static i'm pretty sure that a similar thing (changing wall colours) could be done in flash, with a smaller size, but i imagine the coding/scripting would be quite different.
                Have you done any 'walktrhoughs' with it? I'm looking forward to that!

                  theres something odd going on there with that size, I've got a 7 story office building (with furnishings on 4 of the floors so far) baked thats weighing in at 45mb when exported to the web player, split across a few scenes that load as needed so that there isn't a huge delay in startup time.

                  when exported out for the standalone player its somewhere closer to 250mb though, mostly due to not compressing the textures when saving out to standalone.

                  Also for baking, i was using Flatiron for a while with good results before they added in the pro light mapping. Igor and his crew are a pleasure to work with in terms of reachability and response time. (Chaos-like in customer service.) there are a few quirks with outside light mapping nowadays, and I've got a few things worked up to speed that up, that i may post up someday when i get some time to write them up.

                    Yeah.. That's the standalone version at 76MB; the web player version would be much smaller.

                    The scene was originally just a basic walk through. I'm not a fan of the prefab walkthrough camera script that comes with Unity, and haven't gotten around to working out something better.

                    The last walk through I did using Unity was for a basic police processing area.

                    Thanks for the links!
