The issue here is not shadows or reflections. It is shading. More ambient
light and less diffuse light should reduce the shading effect. I'm not at LPub
right now, so I can't tell you if/how to change this.

Any time you see this kind of problem, use the "Erase Part Image Cache" menu and
rebuild things (disable assembly and PLI generation if you want).
On the topic of scale......
I modified LPub so that the rendering of an assembly image and rendering of part
images for PLI and BOM use the same sized window. This way, if you set the
minimum camera distance the same for assembly and PLI rendering, the bricks
actually come out the same scale. LEGO does not use the same scale for part
images and assembly images, but if you did want to use the same scale, you will
be able to in the future.
I also modified LPub to figure out when PLI rendering parameters have changed,
so it can automatically erase the cache when things change.

| Thanks guys I tweaked ambient up to 0.6 from 0.4 and its definately better I shall see what effect taking difused down has later (and the interaction of the two), but at least I know I can get an acceptable result now. Thanks again William PS - and (...) (20 years ago, 28-Sep-04, to lugnet.cad)
