More testing, on other mechs this time. My results is that some other mechs have a simplified hit box causing very small areas to be "invisibly larger". Typically around leg/hips that angle out. They tend to angle out visually, but remain squared hit box.
My finds:
My finds on where hit boxes actually are (on some mechs): (Red line is where there is roughly a hit box line, blue line is where the hit box should be by visual graphics.)
And then the Spider
So, from what I can discover (I did not see a Raven to test the hit box location on in the testing grounds, but out of the mechs on Crimson Straight) these were the only ones I could really see much of a problem with. The Spider now has a halo of invisible hit box around the top of the mech, it's hunches, it's waist and most of it's legs. The arms are correct and have hit boxes that hug next to the graphics of them.
The Victor I think was a victim of over simplified hit boxes on that one piece of hip/leg. The hit box doesn't cut in like it should, and instead just forms a simple box. The extra space gained by this hit box seems minor, but probably should be looked into.
I also saw what might have been a hit box simplification with the elbow joint of the weapon arm of the Centurion, and the Jagermech seemed to have one bump in it's CT that bumped out more than visually indicated when viewed from the side... and from a very short mech (Locust).
I still have not done live action testing on the Spider, so these hit box changes may not even make any effect on how it plays (for me at least), but I am still not overly impressed with the halo of free hit box placed on the mech. When HSR and HR are fixed, I suspect that the Spider will become worse than a Locust for survivability, which doesn't seem right. However, we can not tell till those larger issues are fixed as to if it really will be a problem or not.
(Can anyone else replicate these issues, or is it just happening to me? This is 3 out of 3 times I have tested it and came to the same problems.)
