So I thought adding a searchlight to the PT Boat was going to be a walk in the park....yeah right! First using the .GR2 Searchlight didn't work because 3D model was rendered solid black. So I had to revert to the SH3 searchlights. But then that didn't work because the beam was all screwed up. I ended up extracting the beam from the SH5 .GR2 file and importing it into the SH3 searchlight .dat file (after tweaking it in Wings3D to match the SH3 searchlight). It's not perfect yet as the searchlight beam has some visual problems depending on camera location to the beam but it's a start.
and I finally have the wake the way I want it (this guy is moving at 40 knots)
