TY to the guy who finished up the entity options for me. was about 4AM in the morning so i figured i needed to go to sleep.

Default

says 0 - default what is the default value?

I think at the moment every game defaults to 128x128. --TomEdwards 01:31, 5 Jan 2007 (PST)

BSP Size Variation

I tried to compile and buildcubemap (in both LDR and HDR) a map with 11 cubemaps configured with the different sizes above the default one, and here are the results so far (the bsp size is 2.4 MB by default) :

  • 64x64 (means 256x256) - BSP: 5.3 MB (0.26 MB per cubemap)
  • 128x128 (means 512x512) - BSP: 15.2 MB (1.16 MB per cubemap)
  • 256x256 (means 1024x1024) - BSP: 58.6 MB (5.11 MB per cubemap)

It almost follows the "double the size, quadruple the weight" rule. The 1024x1024 is really beautiful, but multiplying the weight by 23 is a bit exaggerated for good reflections.
