Tweaking render variables

Render variables are numeric r_* cvars managed by RenderVars.

List and change

developer 1
render list
r_wireframe 1
r_wireframe 0
r_lightmap 1.5
r_normalmap 1.25
r_bloom 1.0
r_exposure 1.1

Changes with live callbacks apply immediately; there is no separate commit step.

Some variables, including material-path switches such as r_deluxe, r_bsp_pbr, and static BSP freezing, apply on the next map/material build. Read the description printed by render list.

Reset and export

render reset
render export
cvarexport

render reset resets render variables only. cvarexport exports the broader cvar set.

Persistence

Render values persist in browser local storage under engine.renderVars. Debug-category variables are intentionally not treated as durable user settings.

Performance tuning

Change one setting at a time and measure with the browser profiler. Common cost controls include post-processing gates, god-ray samples, SSR, area-light limits, and texture settings. Do not copy a fixed preset without testing the target map and device.

The exact current list and defaults are in Render variables.
