The "on rails" effect i believe is solved for the most part. Very rarely do you notice it now. The fix for that is a combination of factors, from draft and CG_height in any given boat's sim file, to enviormental adjustments in the scene.dat, but also what i think more importantly, is offsetting the boats parent nodel in the dat file.
When working on Nine Delta Two, i noticed that by offsetting the parent node backward or forward, AND to one side or the other, it helped create a rolling effect. At least i think it did. I recall seeing a marked improvement after doing that. Originally, the parent node was sitting at 0 on all axis's in the 3d rendering. That puppy rolls nicely i thought. Though it could be made better through one more avenue of approach that is a can of worms i just don't want to open (wave attunation settings in the sim.cfg file). Major domino effect by doing that.
