GLightmapStreamingFactor

float GLightmapStreamingFactor

extern

Smaller value will stream out lightmaps more aggressively.

GNeverStreamOutRenderAssets

bool GNeverStreamOutRenderAssets

extern

For testing, finding useless textures or special demo purposes. If true, textures will never be streamed out (but they can be GC'd). Caution: this only applies to unlimited texture pools (i.e. not consoles)

GShadowmapStreamingFactor

float GShadowmapStreamingFactor

extern

Smaller value will stream out shadowmaps more aggressively.
