Today's Nightly build includes a new version of the F3 lab.
The biggest change in there is that this new lab allows you to preview mission backgrounds through the "Backgrounds" rider that has been added next to the "Ships" and "Weapons" riders. Clicking on it will open a window listing all available missions, sorted by the vp or directory they're in; if you then click on a mission name, that mission's background will be loaded.
It is important to note that, similar to FRED, nebula backgrounds are (at the moment, anyway) not displayed correctly; furthermore, if no ship or weapon has been selected, backgrounds will not be rendered.
This also changes the camera controls, the new controls are:
- Hold LMB + Mouse movement rotates the ship
- Hold RMB + Mouse movement rotates the camera
- Hold Shift + Hold LMB + Mouse movement up/down moves the camera towards/away from the ship
The "Render Options" window has been updated as well: It now includes sliders to directly adjust the -bloom_intensity, -spec_static and -ambient_factor commandline options (spec_point and spec_tube only affect point and tube lights respectively, i.e. lights off of lasers, explosions and beams; they cannot be previewed in the lab) and a checkbox to switch -no_emissive_light on or off.
A few things have been removed: It is no longer possible to switch to different LODs on models or display a ship's debris; the former is something you can simulate by moving the camera far away so that the LOD switch happens "naturally". Debris has been disabled for the moment until I can figure out how to actually make it work within the context of the new lab, this will come back. For similar reasons, you cannot preview the techroom models of weapons; this too will find its way back in, but not for now.
