New Yak-9T screenshots, 4.006 news marks 250th developer update

There have been 250 developer diary updates for the IL-2: Great Battle Series since the first diary in December of 2012. That’s how long the 1CGS team has been keeping this diary going! This week brings some news on the development of the next patch, 4.006, which may be out sooner than you expect. We also get some drop dead gorgeous screenshots for the Yak-9T and a new pilot model. Let’s have a look!

Patch 4.006 is just around the corner

IL-2’s next patch is just around the corner with Han’s update today indicating that the patch is just 2-3 weeks out. It will likely have several updates but it will also have some notable new pieces of content including the Su-152 tank, the Yak-9 and the Yak-9T!

It will also feature the new deferred shading system that has been detailed in recent weeks.

The new deferred shader will make bare metal aircraft like the P-51D have a slightly more matte appearance while maintaining that characteristic metallic sheen. It also enables cockpit gauges to have realistic light reflection and for cockpit canopies to have realistic reflections of the cockpits interiors.

First images of the Yak-9T in-engine

We’ve seen a few development images but these are the first of the Yak-9T in the IL-2: Great Battles engine and it looks superb.

I’m not sure if its the texture work, the deferred shading system, or some combination of the two but the exterior texture detail here is outstanding.

The Yak-9T (Series 1) is a modification of earlier Yak-9 fighters with the biggest differences being the NS-37 cannon, a rapid firing 37mm cannon, and the cockpit that has been moved back to accommodate the cannon. The Yak-9T, despite the increase in firepower, saw only a small increase in weight and essentially performed essentially the same as the Yak-9.

The NS-37mm gave the Yak-9T a powerful anti-bomber weapon and the high fire rate made it suitable for attacking fighters as well. It was also flexible enough to be used against ships and even some tanks – although the primary purpose of putting the larger cannon in was to destroy enemy aircraft more quickly.

2,748 Yak-9T’s were produced making it one of the most produced Yak-9 sub types and the fighter saw service from middle-late 1943 through to the end of the war. After I got into IL-2: 1946, the Yak series become one of my favourites and it was often a toss-up between the Yak-1B, Yak-9 and Yak-9T in the mid war time period. I’m glad that we’re getting those in the Great Battles Series and I’m thrilled that it looks so good!

New German pilot

1CGS also also taken the wraps off of a new German pilot model for the series. This pilot model will be used for 1941-1943 on the eastern front. It’s not slated for 4.006 but it will be coming soon after according to the dev diary.

This pilot model joins the other examples we saw a couple of weeks ago with a new Soviet pilot model also in the works. These are both going to help upgrade the look of the earlier IL-2 series… and once again reminds us that 1CGS not only updates the latest content but they also do a pretty good job of updating older content too which keeps them current.

For the rest of the updates check out the latest IL-2 Developer Diary and go to the 250th update. Quite an achievement!

    Is it deferred shading that make the mountains in DCS look a bit out of focus and far away or have I got it all wrong?

    I’d like to see that in IL2.


    1. ShamrockOneFive says:

      Hrmm the out of focus effect could be one of the cinematic controls for DCS – in photography terms that’s out of focus effect is called bokeh.

      It’s not explicitly related to deferred shading.

      The new shading effect will have an impact on shadows, bright spots, reflections and anything else to do with lighting.


  2. CanadaOne says:

    Ahh, thanks. I know very little about this kind of thing. IL2 is doing great with the eye candy, so I’m sure this will be another plus.

    I’ll look into the bokeh thing. Maybe that is what gives the mountains in DCS that far away hazy look.

      It could also be atmospheric scattering but I don’t think they have that yet. There is some haze which IL-2 also sort of simulates.


  3. CanadaOne says:

    Neither here nor there, but did you see someone posted a mod that apparently makes IL2 run on Vulkan?

    Pretty neat if it works.


    1. ShamrockOneFive says:

      I had to look that one up. Very interesting but also kind of a novelty. The real power behind Vulkan is the more direct communication between game engine and hardware and this mod is using a wrapper to translate calls between one to the other. I can’t see it really being anything beyond a very cool tech demo – and let’s not understate how impressive that is for a moment either! That is cool!
