Render Queues

[!NOTE] Render queues work exactly as implied: The lower the queue value, the sooner it is rendered in the pipeline.

EntropyPortal does not enforce rigid queue definitions. However, for consistency, we recommend following conventions common in other engines:

Common Engine Examples

Range (Approx)	Common Usage	Sorting Strategy
0 - 999	Background (Skyboxes, distant environments)	Order of submission
1000 - 2499	Geometry (Opaque objects, terrain, characters)	Front-to-Back (Minimize Overdraw)
2450 - 2499	AlphaTest (Foliage, fences)	Front-to-Back
2500 - 3999	Transparent (Glass, water, VFX)	Back-to-Front (Compositing)
4000+	Overlay (UI, debug primitives)	Order of submission

Implementation

The InstanceBatcher uses the render queue value provided in InstanceSubmission.

struct InstanceSubmission
{
    // ...
    int32_t renderQueue = 2000;  // Default: Geometry
    bool depthWrite = true;      // Affects sorting direction
};

• Geometry (queue < 2500): Sorted by renderQueue ASC, then depth ASC (Front-to-Back).
• Transparent (queue >= 2500): Sorted by renderQueue ASC, then depth DESC (Back-to-Front).
