Streaming
This section contains settings related to resource streaming.Этот раздел содержит настройки, связанные с потоковой передачей ресурсов.
Streaming SettingsНастройки стриминга| First Frames Force | number of frames to load immediately after the first frame. It will make the scene appear right at the application start-up. Диапазон значений: [0, INT_MAX]. Значение по умолчанию : 60. Консольная команда: render_streaming_first_frames_force (API) |
|---|---|
| Max Threads | maximum number of threads used for streaming. Higher number of threads results in faster streaming, but may cause spikes in case of excessive consumption of GPU resources. Диапазон значений: [1, 256]. Значение по умолчанию : 1. Консольная команда: render_streaming_max_threads (API) |
| Particles Memory Limit | cache memory limit for vertices of particle systems, in percentage of the total GPU memory. Примечание Setting a too low limit for a huge number of particle systems in the scene may lead to rendering only some of them.Диапазон значений: [0, 100]. Значение по умолчанию : 3. Консольная команда: render_streaming_particles_memory_limit (API) |
Preload at World Loading#
| Shaders | Консольная команда: render_shaders_preload (API) |

BudgetsBudgets#
| Loading | time limit for loading graphics resources, in milliseconds per frame. Increasing the limit leads to increasing the streaming performance. However, memory consumption also increases due to a decrease in the resource loading speed. Диапазон значений: [0.0f, inf]. Значение по умолчанию : 1.0f. Консольная команда: render_streaming_budget_loading (API) |
|---|---|
| Textures Destroy | time limit for deleting textures, in milliseconds per frame. The Engine will distribute the textures cleanup process by the required number frames in order to not exceed the time limit. The number of frames will also depend on the amount of content in the scene and the computing capacity. Increasing the limit leads to increasing the streaming performance. However, memory consumption also increases due to a decrease in the texture unloading speed. Диапазон значений: [0.0f, inf]. Значение по умолчанию : 0.1f. Консольная команда: render_streaming_budget_destroy_textures (API) |
| Meshes Destroy | time limit for deleting meshes, in milliseconds per frame. The Engine will distribute the meshes cleanup process by the required number frames in order to not exceed the time limit. The number of frames will also depend on the amount of content in the scene and the computing capacity. Increasing the limit leads to increasing the streaming performance. However, memory consumption also increases due to a decrease in the mesh unloading speed. Диапазон значений: [0.0f, inf]. Значение по умолчанию : 0.1f. Консольная команда: render_streaming_budget_destroy_meshes (API) |
ПримечаниеThe graphic resources are regularly checked for being modified in order to be reloaded or deleted.Графические ресурсы регулярно проверяются на предмет их изменения, для обеспечения их своевременной перезагрузки или удаления.

| Streaming Mode | streaming mode for textures. The following modes are available:
Консольная команда: render_streaming_textures_mode (API) |
|---|---|
| Cache Resolution | resolution for texture cache elements. These minimized copies of textures are used instead of the originals while the latter are loaded. Одно из следующих значений:
Консольная команда: render_streaming_textures_cache_resolution (API) |
| Memory Limit | cache memory limit used for textures streaming. This is a recommended value to aim for. So, it can be exceeded if textures are required to render the current frame. The memory limit is associated with the lifetime: textures are deleted from video memory only when both values are exceeded. Диапазон значений: [0, 100]. Значение по умолчанию : 65. Консольная команда: render_streaming_textures_memory_limit (API) |
| Life Time | lifetime of GPU cache used for textures rendering. The engine deletes textures after this time only if the specified memory limit for textures streaming is also exceeded. Диапазон значений: [1, 60]. Значение по умолчанию : 4. Консольная команда: render_streaming_textures_life_time (API) |
Meshes GPUMeshes GPU#
| Streaming Mode | streaming mode for loading meshes to video memory (VRAM). The following modes are available:
Консольная команда: render_streaming_meshes_mode_vram (API) |
|---|---|
| Memory Limit | memory limit used for loading meshes to video memory (VRAM). This is a recommended value to aim for. So, it can be exceeded if meshes are required to render the current frame. The memory limit is associated with the lifetime: meshes are deleted from VRAM only when both values are exceeded. Диапазон значений: [0, 100]. Значение по умолчанию : 4. Консольная команда: render_streaming_meshes_limit_vram (API) |
| Life Time | lifetime of meshes in video memory since the last time they were accessed. The engine deletes meshes after this time only if the specified VRAM limit is also exceeded. Диапазон значений: [0, 60]. Значение по умолчанию : 4. Консольная команда: render_streaming_meshes_life_time_vram (API) |
Meshes CPUMeshes CPU#
| Streaming Mode | streaming mode for loading meshes to memory (RAM). The following modes are available:
Консольная команда: render_streaming_meshes_mode_ram (API) |
|---|---|
| Memory Limit | memory limit used for loading meshes to memory (RAM). This is a recommended value to aim for. So, it can be exceeded if meshes are required for the current frame. The memory limit is associated with the lifetime: meshes are deleted from RAM only when both values are exceeded. Диапазон значений: [1, 100]. Значение по умолчанию : 5. Консольная команда: render_streaming_meshes_limit_ram (API) |
| Life Time | lifetime of meshes in memory since the last time they were accessed. The engine deletes meshes after this time only if the RAM limit is also exceeded. Диапазон значений: [1, 60]. Значение по умолчанию : 20. Консольная команда: render_streaming_meshes_life_time_ram (API) |
Prefetch CPUPrefetch CPU#
| Collision Mode | mode of asynchronous pre-loading of meshes to memory before they are used. Pre-loading is available only for meshes, which have at least one surface with the Collision flag set. There are 3 modes of loading such meshes to RAM:

|---|---|
| Intersection Mode | mode of asynchronous pre-loading of meshes into memory before they are used. Pre-loading is available only for meshes, which have at least one surface with the Intersection flag set. There are 3 modes of loading such meshes to RAM:
Консольная команда: render_streaming_meshes_prefetch_intersection (API) |
| Radius | radius within which meshes are pre-loaded into memory. The value should exceed the physics radius (for collisions) and/or the radius within which intersections are calculated. Диапазон значений: [0.0f, inf]. Значение по умолчанию : 0.0f. Консольная команда: render_streaming_meshes_prefetch_radius (API) |
For OpenGL OnlyFor OpenGL Only#
The settings below are available for OpenGL API only.Приведенные ниже настройки доступны только для OpenGL API.
ПримечаниеThese parameters should be carefully adjusted for each particular case and configuration as they are heavily dependent on hardware and driver used.Эти параметры следует тщательно настраивать для каждого конкретного случая и конфигурации, поскольку они сильно зависят от используемого оборудования и драйверов.

| Async Buffer Synchronization |
Примечание
Sometimes (depending on the hardware/driver used, e.g. when the main thread is affected by sychronization primitives in other threads) memory allocation may be faster than synchronizations, in such cases, when streaming becomes unacceptably slow, it is recommended to disable buffer synchronization.Иногда (в зависимости от используемого оборудования / драйвера, например, когда на основной поток влияют примитивы синхронизации в других потоках) распределение памяти может быть быстрее, чем при синхронизации, в таких случаях, когда потоковая передача становится неприемлемо медленной, рекомендуется отключить синхронизацию буфера. |
