I want to try Luxrender but I don't know what I'm doing :/

Hi, I’d like to play with luxrender in Blender, but I don’t know what to do, I downloaded the standalone renderer but I have no idea how to use it. I thought you just opened a blend file in it it doesn’t seem to open .blends.

I would prefer to use it directly in Blender though, rather than the standalaone version.

Could someone give a quick rundown on what I do to get Luxrender in my Blender?


you have to go to blender and in pref… find the place called addone and instal luxrender addon.

Read the manual.




Moved from “General Forums > Blender and CG Discussions” to “Support > Lighting and Rendering”

Try getting it to render in blender is a good start, and lower the sample vales to 4 to start and work up, most of the vales are max out.

To get LuxRender working you have to install a “exporter plug-in for Blender”.
This link maybe help full. http://www.luxrender.net/wiki/LuxBlend_2.5_installation_instructions
Myself I find the beta versions of Luxrender come with the add-on in the zip folders and your up and running in a few seconds.

Also check if your PC is 64bit or 32bit and download the correct LuxRender, and if you are using a GPU to do the rendering then chose the OpenCL version.

Here is the weekly builds link which I like to download from as it has everything you need to start or start your renderfarm lol. http://www.luxrender.net/forum/viewtopic.php?f=30&t=9537

Luxrender does a better job then cycles as in a finished image but for speed it can be slower as your exporting every object in the scene including the light meshs and then loading into luxrender.
However soon you will be able to use Luxrender in viewport just like cycles watch the end of this link and see for your self :wink: http://www.youtube.com/watch?v=jk-N4f9ze4k&feature=youtu.be

Thanks for the help, I now have Blender configured to use Luxrender.

Is it already configured to use the GPU to render or do I need to manually specify it?

You have to set it to “hybrid” and chose a integrator which has GPU support for example set it to “Path”.
Don’t forget in-order to get the best performance for Luxrender it is CPU+GPU+Network, and its netrwork is easy to set up and works together better on a wired network.

It is best to search the LuxRender fourms and ask question there as you will find a lot more help from Lux Render User’s ;).

This maybe this link below will be helpful but I warn you it is very out dated and Luxrender has more support these days.

Try this one instead: http://www.luxrender.net/wiki/GPU

Thanks for the links, it’s all sorted now.

anyone made this work under Linux?

I’m using Windows, sorry, can’t help.
