View Full Version : What build do you use?

Hey, guys!

I was just browsing through all those different available blender builds, downloaded one (dark themed (http://www.graphicall.org/builds/builds/showbuild.php?action=show&id=782)) and ran a very basic test: simple cube sitting on a plane, raytraced shadows, AO turned on, 720x512 resolution. With approximate AO the render went 2--3 seconds faster, raytraced AO 5--6 seconds. (Okay, thats on an older 1.86GHz dual core machine with only 2GB ram; on a faster machine this could almost be realtime, I guess ;))

Anyway, I'd like to know, how many of you are using alternative builds, instead of the official one? Oh, and while you're at it: why -- speed advantages, special features, etc.?

P.S. I actually was looking for a build that uses both of my threads for baking fluid sims. Anybody got one for 2.48? :D

Mainly just the official build, but if i have a large scene to render i'll use an SSE3 optimised build as it can speed things up quite a bit.

I just use the official build unless there is some specific tool I need from a different branch, in which case I download the source and build it myself.

mostly official, unless theres something too cool to be ignored in a custom build.

Used to use the monster build by bebraw,
but I don't think he kept it up to date much,
so moved away from it in time, bit sad though,
it included matt's(brkn on these boards) custom rounded theme. :(

That's what I also noticed. Been testing for the last couple of hours with such a build.
Official blender wouldn't even let me bake a fluid sim with 300 resolution without crashing (only 2gigs of ram :shrug: ), SSE, LLE, etc. did.
Tried to render a single frame, with transparency and raytraced AO: official build took about 1m10s, while the optimized one ran 20secs faster. I'd say, it's about 1.3times faster, which, in a very complex scene, would indeed be very notable!

The official 2.48 release is compiled with OpenMP enabled, so it already supports threading for fluid and cloth simulation. I just tested it to make sure ... a sim at a resolution of 100 utilized up to 80%+ of my quad core.

That's strange. I only get about 50%, on a dual core with 32bit XP, that is.

I have the latest 2.48a (i think is "a")

A simulation at a resolution of 200 is using 75% of my 2 xeon 5345 (8 cores)

Cheers.
