Unreal Engine 4.27.2 Source Code modification

Seeking a C++ developer experienced with Unreal Engine 4.27.2 and DirectX to modify the engine's material system, enabling cooked materials to load and render correctly in the editor without upgrading to UE 5.3. The project involves fixing a bug in Unreal Engine 4.27.2 that prevents cooked materials from loading properly in the editor, specifically for modding SDK purposes. The fix must maintain compatibility with existing UE 4.27.2-built games and avoid breaking legacy assets. The goal is to enable cooked materials (.uasset and .uexp) to load and render correctly in the UE 4.27.2 editor, despite the existing shader size mismatch error. Tasks and Deliverables: - Analyze the UE 4.27.2 material system and shader deserialization process to identify the cause of the size mismatch error. - Develop a fix that allows loading of cooked materials into the UE 4.27.2 editor, ensuring they render properly without altering the core material graph, which is not recoverable from cooked assets. - Ensure the solution maintains backward compatibility with existing projects and assets built with unmodified UE 4.27.2. - Test the fix thoroughly to verify that cooked materials load, compile, and render correctly within the editor environment. Required Experience: - Required: Proficiency in C++ programming, especially with Unreal Engine source code (version 4.27.2). - Required: Experience with DirectX 11 & 12, 3D graphics, and shader implementation within UE's C++ engine code. - Required: Deep understanding of Unreal Engine's material system, shader deserialization, and cooked content handling. - Nice to have: Background in engine source modification, shader compilation, and maintaining compatibility with legacy engine versions.

Automation: Google Workspace

Overview: We set tasks and assign them on spaces and so they are filtered over to everyones own Google Tasks section on their google workspace. From this google tasks list we need to use Google Task API to populate these onto a google sheets document, one for each user. From this, they will populate onto a master tracker, there will be a tab for each user.   Furthermore, on the staff's own google sheets document, there is a tab for a timesheet requiring manual data input.   What we need regarding this is the google tasks populated onto the individual staffs google sheets. We then need from this individual staffs google sheets, the timesheet to populate onto a master tracker on the staff members tab, along with all of the staffs tasks, labelled as completed and outstanding.   The other aspect of automation is regarding sending of stock and invoicing. We have a request tracker that is manually filled out per requests from our various shops. We also have an item log of all items/parcels that have been sent out from head office/warehouse.   We need automation to exist from the request tracker when the status of a request has been updated to "sent", for that particular requested item to be populated into the item log as this has now been sent out and is ready for invoicing.

Expert for DHTMLX Scheduler

Hello, We use DHTMLX Scheduler in our SaaS solution and need an expert with good experience with DHTMLX Scheduler. We've noticed that the scheduler has a problem loading recurring appointments. According to our observations, this only affects recurring appointments created with weekly recurrence. If, for example, the scheduler is opened and there is a weekly recurring appointment scheduled for the current day of the week, it is not initially displayed. This only affects weekly recurring appointments that are scheduled for the first time on the current day; further recurrences of a corresponding series do not cause any problems. If you scroll forward and backward one day in the calendar, the appointment appears. Example: We enter an appointment that repeats weekly on Sundays and that occurs for the first time today. This means that the appointment in the database has a start time of 2025-10-05 17:00:00, an end time of 9999-02-01 00:00:00, and a repetition interval of "week_1___0#no." When the calendar is called for the first time, a GET request is made with the following parameters: [from] => 2025-09-29 [to] => 2025-10-06 However, the attached SchedulerHelper.php script does not return this appointment. The script originates from DHTMLX and has already been modified by us in some areas. Can you adapt the script so that the described situation works perfectly? Please keep in mind that the script must be very resource-efficient and must not generate excessive server load. It would be very beneficial if you did not need access to our test system and could solve the task based on the provided script.
