<!-- note to self/anybody:
The instructions below explain what I did to enable motion blur in luxblend internal rendering in Blender for luxrender 1.7(?). That is, not blendluxcore.
Absolute Exposure worked fine. The other two (Degrees and Normalized) made some blur but it looked strange. With Absolute, motion blur was possible to go above 1.0, pushing the blur beyond the location where the object is in the second frame.
For blendluxcore, could this setting be made simpler to the user? One setting, called for instance Range, with a Start and End with values 0 and 1 respectively (and not possible to set it above 1). Range would be just another name for Absolute Exposure but clearer to the user. 0 to 1 to get the motion blur the user might expect. Tweak the values to get a shorter blur.
 
Instructions for luxblend:


Insert a key frame for the objects that will be moving. Move forward one frame. Move/rotate your objects and insert another key frame. Go back to the previous frame. Select the camera and enable motion blur in your exporter. Set exposure to 'Absolute', Shutter open time: 0 and Shutter close time: 1. Render like a normal still image.

Motion blur doesn't support mesh deformations (modifications to the mesh shape), but only object transformations (moving, scaling, and rotating). However, there is a workaround for these limitations which is described in "Alternate method" section down below.

With this approach you can workaround all current LuxRender limitations like no motion blur for emitters. However fast moving objects may require quite a lot of subframes and even then some discreteness (individual frames) will be visible.
