Why are plant shadows discontinuous in specific resolutions' outputs while preview is normal?

If the ↓ output effect occurs, use the D5 client version after 2.5.2 and modify the relevant parameters to solve this phenomenon. (If you are not sure whether you can use this solution, please contact us for specific confirmation or operation.)

Phenomenon

Preview is normal, but output of a specific resolution image or a specific video clip appears to have plant shadows truncated.

Output specific (resolution) clips, plant shadows not linked

2k resolution image preview/output is normal, 4k/8k resolution image output, tree shadow is cut off.

Operating procedure

1. Save a backup of the current abnormal scene and exit D5.

2. Find the Engine.ini file under the corresponding Config path. Config path: %localappdata% d5_immerse/Saved/Config/

• The "Administrator" in the screenshot is the window system user name, which may be different for each user;

• AppData is a hidden folder, you need to tick the hidden items in [View/Hide].

• The Config path generally shows only the folder named Windows (but may show both Windows & WindowsNoEditor folders).

Note: If only the folder named Windows is displayed, only the Engine.ini file under the Windows folder needs to be modified; if both Windows & WindowsNoEditor folders are displayed, the Engine.ini file under both folders need to be modified.

If only the folder named Windows is displayed, only the Engine.ini file under the Windows folder needs to be modified; if both Windows & WindowsNoEditor folders are displayed, the Engine.ini file under both folders need to be modified.

3. Add the corresponding fields in the Engine.ini file, modify the parameters and save the changes. Field： [/Script/Engine.RendererSettings] r.RayTracing.Geometry.InstancedStaticMeshes.LowScaleCullRadius=15000.0f

• The default initial value of the parameter is 15000.0f

• When modifying this parameter, you need to close D5. After modifying the parameter, reopen D5 and test the output with a specific resolution to see if the output is normal, in order to verify whether the modified parameter is sufficient.

• If the output with the specific resolution is still abnormal, modify the parameter to a higher volume. For example: If the parameter is 20000, and the output of a specific resolution image/specific clip is still abnormal, then modify the parameter to a higher value (20000→30000) and save the Engine.ini file. Then restart D5 and render the specific resolution image/clip again for verification.
