Sadly doesn't fix it for me. What I've found is that if I render a scene with the default LIGHT1 it produces a shadow, and THEN I can load extra files (or delete the light and import a new LIGHT1 from the library - one I prepared earlier) which will render shadows... BUT if I don't render first then any light from the library, regardless of internal name, will not render depth-map shadows. Nor will any .pz3-contained lights. This strongly suggests that for SR4 even with "tweaks" like the above I'm limited to 3 shadow-casting lights :( There does seem to be a link to light name with this problem, but it also looks to me like there's an issue with shadow map creation too? Cheers, Cliff (who wishes CL would acknowledge the problem and pledge to do something about it - silence is not the best source of information)
