Lighting, Please Help!
I have a very large scene and I just recently discovered the envMapLight (formerly sky.mll) script and I love the renders it produces – except my textures all look flat. The problem is bump maps. Obviously – since there are no lights physically placed in my scene there’s no light for a bump map to calculate results from.
I’ve tried including point or directional lights at low intensities with raytracing on in addition to envMapLight, but no dice. I get either too bright a scene or not bright enough, and still no bump maps. I really want to continue using envMapLight – but does rayDiffuse have better options for my problem? I’m at a loss, and pulling my hair out with trying to get good GI (without MR) on this scene.
Any suggestions? Thanks!

The problem of course, is how to get my bumps back, since ambient lighting doesn't show bump maps.

One thing that is occuring to me though is to make sure that "use default" light is turned off in the render globals as that adds a flat ambient light to everything in your scene...

You might try toning the GI down if possible and using some strong, main lights in addition to them in order to... "bump" your bump.

I've tried several, several methods from depth to raytrace to GI_Joe (which won't work right in a command line render) to domeGI to rayDiffuse (couldn't get the rayLight working) to combinations of them to everything else.
I notice on many of those "soft" looking renders you see out and about, they also don't have any bump in them, so I'm not sure what's up. I also don't know how to tone down the GI, since I'm using envMapSky (formerly sky.mll) and it's poorly documented for my n00bhood.
