Was wondering if anyone knew of any renderers i can use with 2.59 on ubuntu 11.04.
i got povray through the addons menu in blender ( i just checked the box dont if thats the right way to get it) but it just give me a black render.
all the other renderers ive looked at just dont seem to a version that will work on ubuntu
go to graphicall.org they have build that have yafaray… ask a someone if they could do a lux build. <br>
edit… not sure if lux has a linux version…(i guess they do have a linux version) also, you can use cycles, yafaray… etc. maybe mitsuba. not sure.
cycles
Simply checking the box doesn’t allow POV-Ray usage, you also have to download the program executable. Not sure how active development is on POV these days, but definitely check out Yafaray and Mitsuba.
im rendering a picture with Yafaray right now… its looking pretty nice… <br>
i set it to “pathtracing”, Ray Depth 2, Path Samples 50, Depth 8, Anti-Alias setting, 1 pass, 4 samples. (gauss)<p>
its rendering slow as heck(on my 6 year old computer) but its looking pretty nice… 
yafaray can use Adaptive Sampling to reduce render time, and pathtracer recently was optimized to use less path samples than previous versions. The minimum number of samples per pass is 2; lower than that will not use adaptive sampling and the final render will look jaggy
the basic sampling strategy for pathtracing is :
pathsamples= 16
AA samples = 2
AA inc = 2
Threshold = 0.008 or lower values (this determine how much noise will be reduced every pass. for dark/low contrast images, threshod must be even lower)
AA passes: try several passes and stop the render when the image looks ok
But pathtracing is only one of the alternatives. You can try Photon mapping with Final Gather or the last Stochastic Progressive Photon Mapping algorithm… this 2 algorithms are faster than pathtracing
ok so i’ve tried most of them now, yafray does’nt have any for ubuntu 11.04
i dont know where i download the povray executable.
mitsuba doesnt work at all
i have aqsis but cant open my blends in it
tried luxblend, i cant render internally into blender but i can render the added test file, so i tried exporting my blend as a lux file, no joy
getting really fed up to be honest
im on ubuntu 11.04 natty wharhal 64bit
using blend 2.59
someone must have a renderer working for them on the same? care to tell me what and how
Blender/Yafaray for 64 bit 11.04 - http://graphicall.org/linux//64bit/?keywords=yafaray
Download it, unzip it, launch Blender. Yafaray is bundled with it and there is no need to install. At most you would have to enable the Yafaray exporter in User Preferences. Also, contributers at graphicall generally update regularly, so you can keep going back for more. 
Enjoy.
LuxBlend should work perfectly well on your OS and hardware with Blender 2.59. If you start Blender from the command line and post any error messages that you get over here or on the LuxRender forum getting you started shouldn’t take too long. Some things to check right away are if your scene has a light source, if the “run renderer” checkbox is ticked and if so, if you’ve set the correct path to LuxRender in LuxBlend.
