Talk:Env cubemap

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.

Each cubemap texture contains six different images. Use a zip application to look inside the BSP files. --TomEdwards 12:44, 21 Sep 2008 (PDT)

Yes, I know that. But doubling the resolution of the cubemap is supposed to quadrule its weight. And that's not really the case, it's a bit more greedy. I made this test to try to estimate the size of a BSP without having to compile it each time in full quality with each different resolution of cubemaps. --NykO18 05:06, 22 Sep 2008 (PDT)

Thanks for that test mate, saved me a hell of alot of time :D.

EDIT: Oh and the size depends on the amount of color information in the screenshot taken, just like pressing F5 --Jenkins08 01:39, 28 Oct 2008 (PDT)

HDR cubemaps created even though map doesn't use HDR?

I noticed my map generated HDR cubemaps even though the map is not using HDR. Can I remove those with pakrat, or will that mess anything up? --Pandaboy 02:09, 6 December 2011 (PST)
