The developers abandoned Unreal Engine 5.1 in favor of version 5.5.4. The changes in the engine turned out to be so large-scale that the transfer process itself turned out to be far from simple.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This is <a href=\"https:\/\/dev.ua\/news\/slozy-rozrobnykiv-stalker-2-1788419655\" type=\"link\" id=\"https:\/\/dev.ua\/news\/slozy-rozrobnykiv-stalker-2-1788419655\">reported<\/a> by dev.ua.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The problem was that during the development of S.T.A.L.K.E.R. 2, <strong>the Unreal Engine 5.1 engine underwent significant changes and significantly differed from the initial version<\/strong>. During the development, <strong>the GSC team seriously reworked it<\/strong>, <strong>adding a lot of its own developments and code<\/strong>. Therefore, a regular update of the engine actually turned into a complex technical work of adapting the engine that had already been modified for the game.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The scale of the difficulties was succinctly conveyed by the COO and head of creative direction of GSC Maria Grygorovych. When asked about the transition, she replied:<\/p>\n\n\n\n<blockquote class=\"wp-block-quote td_pull_quote td_pull_center is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">&#8220;Can I cry?&#8221;<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">What were the difficulties<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Maria Grygorovych explained that <strong>the main problem was the deep adaptation of Unreal Engine 5.1 to the needs of S.T.A.L.K.E.R. 2<\/strong>. The team added a large amount of its own code to the engine, which made its update much more time-consuming. According to her, it is much easier for projects with a minimally modified, \u201cvanilla\u201d version of the engine to switch to the newer Unreal Engine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Yevhen Grygorovych called the transition process \u201ccrazy.\u201d<\/strong> The game was initially developed on Unreal Engine 4, and later the studio switched to an early version of Unreal Engine 5. At that time, <strong>the engine did not yet have all the necessary tools for working with a large-scale open world<\/strong>, so <strong>GSC had to independently refine it<\/strong> and create its own systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Later, Epic Games added solutions with similar functions to new versions of Unreal Engine. However, to switch to them, GSC had to actually redo a significant part of the work already done. Because of <strong>this update<\/strong>, <strong>S.T.A.L.K.E.R. 2 required much more time and effort from the team<\/strong> than a similar process in other projects.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Despite the complexity of the work, <strong>GSC believes that switching to a newer version of the engine was the right decision<\/strong>. According to studio executives, after the update, S.T.A.L.K.E.R. 2 became more stable and demonstrated better performance.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>GSC Game World owner Maksym Krippa has previously repeatedly spoken about the importance of long-term support for the game and the further development of the S.T.A.L.K.E.R. franchise<\/strong>. Even after the release, the studio continues to invest resources in the project, which, in particular, allowed for such a large-scale engine update.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why GSC has no plans to return to X-Ray<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>The studio is not even considering a return to X-Ray<\/strong>, which was used in the previous parts of S.T.A.L.K.E.R.. The studio has not even considered it. Maria and Yevhen Grygorovych noted that <strong>the main problem with such a decision is the lack of specialists who have sufficient experience working with this engine<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There is another reason to stay on the Unreal Engine. <strong>Maria believes that working with a standardized engine gives GSC developers broader opportunities for their future careers<\/strong>. It would be much more difficult for specialists to find a new job if their experience was limited only to the studio&#8217;s own engine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the same time, GSC does not believe that Unreal Engine is a universally correct choice for everyone. Maria emphasized that each company must independently determine which tool best meets its needs. For GSC, Unreal became such a solution.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote td_pull_quote td_pull_center is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\">\u201cAn engine is a tool,\u201d Yevhen Grygorovych concluded. \u201cYou choose the right tool for the right project.\u201d<\/p>\n<\/blockquote>\n\n\n\n<p
