BAdler Posted May 28, 2014 Share Posted May 28, 2014 Update by Adam Brennecke, Lead Programmer and Executive Producer Over a year ago, in Update #49, we showed you the first movie of Pillars of Eternity. The movie showcased a beautiful scene in the Dyrwood complete with dynamic lighting, per-pixel occlusion, dynamic water and waterfall, and a day-night cycle. In this update I would like to give you an inside look on how these images are put together and rendered in the game, and I will cover new rendering features that we've added over the past year to address feedback from our backers about how our characters look in the scene. Warning: things might get technical! E3 We are going to be going on update hiatus for the next three weeks as we prepare for E3 in Los Angeles. After E3, the next update will feature the final classes covering The Front Line (fighters and barbarians). At E3, the team will be showing Pillars of Eternity at the Paradox booth behind closed doors. To avoid spoiling what we will be showing, we will be saving these moments until you get to play it. Because we want to include you in the experience, we will be taking photos at the booth, and in a future update we will be sharing more screenshots from the demo. To give you a small taste, here's a sneak peek at a scene that will be shown at E3: Rendering TimeBackgrounds As we mentioned previously, our beautiful backgrounds are rendered out of Maya as a 2D image. They are very large images, sometimes over several gigabytes of raw data, and before the images get into the game we run a program that compresses the data. Maya renders out the backgrounds in four layers or "passes": final, depth, normal, and albedo. These passes are combined together in Unity for per-pixel occlusion of 3D objects, and for real-time dynamic lighting. When we bring the backgrounds into the game, they look like a flat 2D plane, and when viewed in Unity's editor the whole world has an awkward skewed look to it. The illusion comes together only when an orthographic camera is placed at the perfect angle. Characters Next we overlay the 3D world on top of the 2D rendered image. The characters are dynamic 3D skinned meshes that are animated and then rendered into the scene with a variety of shaders and materials. Our default material that we use on most characters includes a normal map (adds tiny variations in surface detail), specular map (adds shininess), and an albedo map (adds the base color). The default material also supports a tint map, which allows our designers and you to customize the colors of armor, hair, and skin. We have other shaders that can change the look and feel of characters. For example, we have a metal shader for armor that adds an extra level of shininess and can reflect the environment via an environment map. A Cloth shader removes the shininess, and allows the character artists to make outfits made up of cotton, wool, and satin. We have special materials, like an emissive shader that isn't affected by light, used for the fire-godlike, ghosts, spectres, and the windows seen in the screenshots and video. Because the characters are 3D, they need to be lit differently than the background image. We use a system with two directional lights. The first directional light is the key light and typically matches the sun color and intensity in outdoor scenes, and this light can be modified by the day-night cycle to cast moonlight at night. The second directional light is used as a fill light to make sure the "back side" of a character isn't in total darkness. The two lights are adjusted per scene depending on the pre-rendered light settings to match the sun direction, mood, and desired atmosphere. In addition to the directional lights, we use dynamic deferred lights that can affect the background and characters. For example, if a torch is placed in a scene, the torch can illuminate both the 2D environment and a 3D character standing nearby. In addition, deferred lights are used for spell effects; a fireball explosion emits a burst of light, brightening up a dark dungeon room. Bringing it all together We noticed, and so did many of you, after releasing our first few screenshots, the 3D characters were not matching the 2D rendered scene as much as we would have hoped. So we put our thinking caps on, and we came up with new features since our first batch of screenshots, including dynamic ambient and a shadow control system. To really make sure the characters fit in the scene, we came up with an ambient system that samples color from the 2D background, simulating a quick and dirty global illumination model. Characters pick up subtle color variations depending on where they are standing and what type of environment they are in. If a character is standing in a lush green jungle, it will pick up a subtle green hue from the light reflected off the environment. Game programmers love fast and cheap methods, and the ambient system gives us great results with little impact on rendering performance. Ambient before and after: Another feature that we've added recently to solve the issue of grounding characters into the scene is a system to shadow 3D characters when traversing into dark shadowy areas in the 2D image. The new system samples a low resolution image map which controls the contribution of the directional sunlight on the character, and to avoid double shadows, the same image controls the value of the dynamic shadow map. Lastly, to better match the 2D and 3D shadows, we color the dynamic shadow to match the 2D rendered shadow color (which often has a blue hue to it). Shadow Blending before and after: To tie everything together, we can optionally add post process effects. In this scene, we've added a very subtle bloom effect that effects both the environment and characters. I hope you didn't get lost in all the technical talk! The important thing is that we hope you like the end result. We are satisfied with where we are at, but we always have a few ideas on how to improve the look and quality of the graphics. Improving the look of the game will be an ongoing process until we ship... and beyond. If you have any questions, please ask in our forums! Thanks for reading. 34 Link to comment Share on other sites More sharing options...

Sensuki Posted May 28, 2014 Share Posted May 28, 2014 (edited) Real cheeky inclusion of dynamic cloth at the end, hahaha. Great update I noticed there's no more specular or diffuse map image, why the change from those and the inclusion of albedo (just curious). One obviously is size I guess.

Great update I noticed there's no more specular or diffuse map image, why the change from those and the inclusion of albedo (just curious). One obviously is size I guess. We still have a specular contribution in the alpha channel of the albedo map. It's very subtle and difficult to see in the video and screenshots, so I decided not to include it. 1 Follow me on twitter - @adam_brennecke Link to comment Share on other sites More sharing options...
IndiraLightfoot Posted May 28, 2014 Share Posted May 28, 2014 (edited) Thank you for the "sneak peak", Adam! Perhaps it's a building that's part of a complex like an acropolis, situated on top of a hill or a mountain! That screenshot is absolutely amazing. It's definitely a place worthy of exploration and adventure over and over again!

Amentep Posted May 28, 2014 Share Posted May 28, 2014 I like the way the video looked. Good stuff. I cannot - yet I must. How do you calculate that?

Darth_Gandalf Posted May 28, 2014 Share Posted May 28, 2014 Superb update. I can really tell that you guys have been putting in a lot of hard work on this. By the way, with that surprising ending, does this mean that Aloth is a confirmed companion now? "You shall not pass!" Link to comment Share on other sites More sharing options...
Nonek Posted May 28, 2014 Share Posted May 28, 2014 The Dyrford theme really grows on you, excellent update thank you ladies and gentlemen. 1 Quite an experience to live in misery isn't it? That's what it is to be married with children.I've seen things you people can't even imagine. Pearly Kings glittering on the Elephant and Castle, Morris Men dancing 'til the last light of midsummer. I watched Druid fires burning in the ruins of Stonehenge, and Yorkshiremen gurning for prizes. All these things will be lost in time, like alopecia on a skinhead. Time for tiffin. Tea for the teapot!

IndiraLightfoot Posted May 28, 2014 Share Posted May 28, 2014 (edited) I must commend you for that brilliant running animation on that Aloth?-figure with a fluttering cape in the last seconds of the video. I always thought my characters looked akward when they were running in NWN2, but this running animation is simply brilliant - one of the best ones I've seen. Kudos to the animator! :D Edited May 28, 2014 by IndiraLightfoot *** "The words of someone who feels ever more the ent among saplings when playing CRPGs" *** Link to comment Share on other sites More sharing options...

Quadrone Posted May 28, 2014 Share Posted May 28, 2014 Yes, very nice update. Game just looks fantastic now, moreso then before. Spiffy winged helmet on that guard there. Btw. indirect confirmation of fire godlike as playable race? Only one point of grievance: Do I understand that right? You'll be at E3 show of footage and talk to the press but all behind closed doors? Meaning we (the fans) will get nothing out of it, neither directly or indirectly via the media? Except for some pics of the event several weeks later? 1 Link to comment Share on other sites More sharing options...

All we were promised as backers is a game and a chance to get a much deeper look at the development process, no one ever said we would get unlimited access. 2 Link to comment Share on other sites More sharing options...

The press has already seen a lot of the game that we haven't, in the production spreadsheet there were three press demos planned (none of which we have seen). This is nothing different. The team decided back in 2012 that they would keep the story under NDA, which the press will be subject to as well. Hopefully we do eventually get a gameplay video though like Shadowrun Returns and Wasteland 2. 1 Link to comment Share on other sites More sharing options...

I don't know, but what I do know, since I'm a bit savvy when it comes to meteorites, that what we see here is in all likelihood a temple built around a huge meteorite! It's a huge meteorite body, mainly composed of metal, and it's characteristically thumbprinted (so most likely, it's having iron as its main component). Any ideas what kind of cult this may be? And what are the implications for the clash between science, magic and superstition? Compare, for instance, this to the largest meteorite in the world - the Hoba meteorite: 2 *** "The words of someone who feels ever more the ent among saplings when playing CRPGs" *** Link to comment Share on other sites More sharing options...
Jotra Posted May 28, 2014 Share Posted May 28, 2014 I just love how this game looks. It's exactly like IE games brought to modern day. If I had one request though it would be the show some areas that really embrace the high fantasy aspect of the game like eg. Temple of Talos in BG2.

All we were promised as backers is a game and a chance to get a much deeper look at the development process, no one ever said we would get unlimited access. Did I say anything about unlimited access? Did I demand anything? If there is any kind of coverage during or shortly after E3 that is all I'm hoping for. But to me it sounded like any kind of coverage made at E3 would not be released at all until Obsidian chose to do it themselves. Knew someone would bring this up.

Hopefully we do eventually get a gameplay video though like Shadowrun Returns and Wasteland 2. Well, like I just said now, I don't demand to have any and all info revealed to me but this is E3 after all. And considering how much further along Eternity is now and how big a media spectacle E3 usually is, I wouldn't have been surprised if there were some extra scraps to pick up for us.

Gumbercules Posted May 28, 2014 Share Posted May 28, 2014 Great update! Everything definitely seems to fit together much better than before, and it'll look even better once the 2D details are painted on. The dynamic cloth at the end also looks really good. Do hoods always stay up, or can they be raised and lowered? I agree with those saying the music grew on them since it was first revealed. As with pretty much every other aspect of the game, I'm still hoping for some more unusual stuff, but what's been shown so far is a good baseline. I don't know, but what I do know, since I'm a bit savvy when it comes to meteorites, that what we see here is in all likelihood a temple built around a huge meteorite! It's a huge meteorite body, mainly composed of metal, and it's characteristically thumbprinted (so most likely, it's having iron as its main component). Any ideas what kind of cult this may be? And what are the implications for the clash between science, magic and superstition? If I had to guess I would say that it's an ancient Engwithan ruin with a giant chunk of adra, not a meteorite, in the middle. The architecture definitely looks more interesting than before; I like the scaly decorations on the columns. 3 Link to comment Share on other sites More sharing options...
Valorian Posted May 28, 2014 Share Posted May 28, 2014 Beautiful as usual. I'm trying to avoid looking at all the maps, models and other visual stuff too much, but it's not easy. I'd like everything to be a surprise when I finally play this game (well, except the systems and combat mechanics). Link to comment Share on other sites More sharing options...
