It seems to talk about volumetric data: http://paulbourke.net/dataformats/cube/

How is this related to camera response :?:
Oh, my bad, that's unrelated. Sorry to waste your time.
I think it is related, it is just quite strange to use a volumetric format for a camera response.
Oh... Well i don't know much about science behind, but from what i've gathered from the quick look, it seems to be something about data in cubic form (i've also stumbled on cases used for chemical, atomic structures). In case of LUTs i think it's about 3d color space transformations (3 curves RGB/XYZ) using similar or same rules. But really IDK.

BlendLuxCore now contains an option to automatically calculate the best step size and max. steps for smoke simulations:

Nice one, you keep surprising 8-)

One other thing i've been wanting to ask about BiDir settings.
Since by using BiDir engine, there's no clamping option available and fireflies are quite problematic to resolve, is it possible to have SuperSampling exposed (assuming that it hasn't been removed)?

The addon now shows an error message if the old LuxBlend addon was enabled and explains the next steps you have to take to make everything work.
Unfortunately I can't hide the traceback on top.

The min. epsilon setting is now exposed (should be used only by advanced users or when a developer tells you to change it due to a bug report).

Do you have an old LuxBlend installation? Disable it in the user prefs, save user prefs, restart and try again.
By the way 2.79b is out (but it does not matter for this problem).

Hi, I don´t had an old Luxblend installed.
Tested again with Blender 2.79b but same error. :/
No idea how I got it to work before.

Cheers, mib
