Syntax
struct FMeshDrawCommandPrimitiveIdInfo
Remarks
Container for primtive ID info that needs to be passed around, in the future will likely be condensed to just the instance ID.
Variables
| Type | Name | Description | |
|---|---|---|---|
 |
uint32: 1 | bIsDynamicPrimitive | Set to true if the primitive ID and instance data offset is a dynamic ID, which means it needs to be translated before use. |
 |
int32 | DrawPrimitiveId | Draw PrimitiveId this draw command is associated with - used by the shader to fetch primitive data from the PrimitiveSceneData SRV. |
 |
int32: 31 | InstanceSceneDataOffset | Offset to the first instance belonging to the primitive in GPU scene. |
 |
int32 | ScenePrimitiveId | Scene PrimitiveId that generated this draw command, or -1 if no FPrimitiveSceneInfo. Can be used to backtrack to the FPrimitiveSceneInfo. |

FMeshDrawCommandPrimitiveIdInfo
(
int32 InScenePrimitiveId, |
Use this ctor when DrawPrimitiveId == ScenePrimitiveId (i.e., for scene primitives) | |
 |
FMeshDrawCommandPrimitiveIdInfo
(
int32 InDrawPrimitiveId, |
Use this ctor when DrawPrimitiveId may be != ScenePrimitiveId (i.e., for dynamic primitives like editor widgets) |
