Update: Nov 13, 2021. I discovered a bad Java error that resulted in the generation of a googleplex of repeated Java errors that would bloat log.lst to Brobdignagian dimensions.

The full archive has been updated.
Update: Sep 28, 2021. Added expanded 6dof range limits in the cockpit class. Aside from minor touches to a couple of textures, the updated four classfiles are all that's needed if you've downloaded this already.
The Ki-44 II Hei's office has had a bit of a facelift! Note that for some reason the reticle is always on, which is the stock state in B.A.T., even. I've tried to determine how to get it to toggle on/off and vary in brightness, but no joy. I think this derives from the use of base code for the earlier Shokis and their tube sights.
The two toggleable PoVs have been moved a bit farther forward. This screenie is taken from the farthest rearward position afforded by a head tracking system when the 'normal' PoV is selected. If you're not using a head tracker, the viewpoint will be a bit farther forward than this, which provides an improved sight picture compared to the stock PoV.

A closeup of the gun sight. The sun shade is cleanly transparent, and not somewhat milky like the stock shades tend to be. On the far left, note the iron sight's post (flipped upside down here). In particular, the two squat cylinders and the bead will be seen to be 'glowing' a bit too brightly (this gets even worse when the plane is pointing directly at the Sun). This is the stock condition, resulting from the bad surface normals, which are now fixed. The crash pad had been built anew.
Here the PoV is still tied to the 'normal' view, but from a vantage at the farthest forward position a head tracker provides. For those not using a head tracker, the 'gun sight view' will be a bit farther aft of this, but not by much. The expanded 6dof range limits--added after this image was taken--will afford an even larger range of virtual head position. Now you can get right up there and 'smell' the sight's crash pad!

WxTech's gun sight and other cockpit tweaks for the Ki-44 II Hei.
Original release Sep 23, 2021.
Update: Sep 28, 2021, for addition of expanded 6dof range limits in the cockpit class.
Gun sight changes:
- Added a collimator lens reflection.
- Improved the reflector plate and sun shade glass.
- Fitted the reflector plate more exactly to its support; there were obvious gaps.
- Reduced the size of the reticle mask.
- Improved the reticle texture (for one thing, the outer ring gaps are correctly wider).
- Fixed a number of bad surface normals on the iron sight fixture.
- Added some polygons to the sun shade support, to bulk it out.
- Lowered an edge that protruded a little into the bottom edge of the reflector plate.
- Fixed the gun sight mount, to remove the odd transparency cut-out on the right side (due to the instrument panel texture originally being used).
- Re-built the crash pad, and supplied a new, separate texture.
Other changes:
- Repaired bad texture mapping for the panel coaming (instrument panel shade).
- Reversed the canopy perspex surface normals.
- Made some improvements to instrument textures, mostly in the form of better bezels.
- Tidied up the gauge needles.
- Moved the slip ball behind the turn rate needle, and tweaked the ball texture size and tone.
- Cleaned the compass card (rotating drum) texture a bit, and made the top surface dead black.
- Made invisible the tiny triangular texture that is the compass drum reference.
- Adopted some better cockpit textures from the Ki-44 II Ko.
- Evened out the tone on the crank handle for the cowl flaps.
- Moved both the CAMERA and CAMERAAIM view hooks a bit farther forward (located in Body.msh).
Cockpit class file changes:
- Added hysteresis to the VSI (it was formerly FAR too crisp in its response).
- Added code to expand the range of translation of the PoV in the fore-aft, left-right and up-down axes.
The cockpit class is from B.A.T., but should work fine for 4.12. I added lag in the response of the VSI (vertical speed indicator), because the stock response was virtually instantaneous. If you prefer the stock behaviour, delete or disable these four classfiles (but then you would also lose the expanded 6dof functionality). If you use these classes, make sure this folder lies above any other folder that might contain the same classes (such as #WAW3\Classes-ObjectsAir\, in B.A.T.).

NOT undertaken to improve yet:
- Damaged gun sight.
- Damaged gauges.
- Gauge night textures.
- The fact of this cockpit/plane not supporting the reticle brightness feature, and so the reticle is always on, and at a fixed brightness.
As always with my mods, this work is made available for use by any and all, for any purpose, without restriction.
