Questions about converting to T3D

Had a license for T3D for a while but only just starting to play with it and we're looking to upgrade our game (Z-Day) from TGEA to T3D. There's a few queries I've got and thought I'd ask here and hope for some quick answers than hunt around for everything.

Advanced Lighting looks stunning but unfortunately given the size and complexity (it's a city) of our map I'm doubtful it'll perform.

1. Switching between AL and BL is done in the World Editor - any reason this can't be added to users options so people with high-end cards can use AL and others use BL? (side note: T3D crashes every time I switch between AL and BL in some maps - works ok in the blank mission, anyone know if this is a known bug?)

2. Shadows in BL are odd, the sun casts shadow on a building (it's a DIF) but not on the terrain itself - is there something I need to do to get shadows on terrain in BL?

3. Tried converting DIFs to Collada using the world Editor but:
- Using "Export Interiors to Collada" pops up the Gui, lets me select which Interiors but then doesn't seem to do anything
- Using "Export to Collada" saves the object but with no materials, LODs or the inside of the building

Am I missing something here?

4. Any idea how to enable SSAO? tried to use SSAOpostfx.enable(); but it didn't seem to do anything.

5. pureLIGHT - is it really as good as it seems? also I couldn't find any info on the process i.e. does it integrate with T3D to import your mission directly? load it from file or do you manually have to reconstruct the level manually in pureLIGHT?

6. Seem to remember someone saying (think it may have been Steve Acaster as I follow his blogs) that BL with Purelight is similar to AL but you don't get normal maps -- does that mean normal maps don't work in BL? (don't worry if this doesn't make sense I'll go hunt for the blog/post and see what it actually said).

7. I'm getting a lot of errors saying when porting the mission from TGEA with "Zone Overflow! Object will NOT render correctly. Copying out as many as possible" --- any ideas what this means? or what the problem is?

8. Flashlights - I saw the screenshot someone posted about them working, if I remember it was as easy as adding a spotlight to the weapon image, does this work in BL? or do you need the dynamic lighting in AL?

9. Web PLugin - How does this work, is all the content downloaded to the clients pc for their machine to process like a normal install or does the webserver handle all the processing (rendering, physics,etc) and just stream the video to the clients browser?

Edit: Thought of a number 10

10. Mesh Road Editor is great but doesn't seem to like Junctions either T-junctions or crossroads - any tricks for creating these or is it just a case of modelling junctions seperately and linking them up with the mesh road for the rest?



Thanks to anyone that takes the time to answer any of these.
