Lightweight buffer rendering without node overhead in game engines
A simplified, lightweight API for rendering entire scenes to buffers for use in successive custom postprocessing effects, without requiring the overhead of managing scene nodes and full node-based infrastructure.
SOURCE TRANSMISSION
Not everything in Godot is all that robust/well-baked but two very nice things are 1. how easy it is to render things to a separate buffer and then use that buffer as a texture/frag shader input 2. it having a native conception of "are you mousing over this 3d collision box"
“Regarding your first point, I think subviewports are really nice when I want render a whole scene to a buffer, but I wish there was a more lightweight way to do this without needing nodes and stuff, for successive custom postprocessing effects for example”
CLASSIFIER RATIONALE
The post expresses a genuine technical need: a lightweight API or mechanism for rendering scenes to buffers for custom postprocessing without the overhead of scene nodes. This is a specific gap in game engine tooling. The reply adds technical context (successive custom postprocessing effects) that clarifies the use case. While technical and niche, it represents an unmet demand for a category of tool/feature that would benefit game developers.
