This is an important patch with loads of fixes to the K4s. Originally this patch was going to be included with the streamlined variants but was pushed out early due to a bug that needed immediate attention. The streamlined K4s will begin development once the T1 is released, which will be before the end of the month. I haven't forgotten about the streamlined K4s, I know a lot of you are excited for them, but please remember that I can only work on one thing at a time so please be patient!

• Added Headlight
  
• Added Firebox glow, currently uses the cab light controls

  These additions to the K4 are to make them more inline with other models like the L1, feedback on things like the headlight brightness/radius is greatly appreciated.

• Added custom non-looping whistle

  The audio for the K4s and for all models in the Keystone Project is a topic we are actively researching, nothing here is finalized and open to community feedback and suggestions. Over the next few months we would like to start rolling out patches for each of our models to test different audio samples and to get community feedback.

• Side Panels and Main meshes are now combined into one mesh

• Now supports livery creation

• Fixed a bug with the Locomotive and Tender offsets, couplers, wheels, and lengths causing them to clip inside other wagons.
  
• Removed an accidental floating bit of the valve gear
  
• Tweaked the position of the smoke effects due to a side effect from fixing the Locomotive offsets
  
• Moved the player spawn offset to be more inside the cab

  After receiving various reports, the issue with the tender and locomotive clipping or uncoupling themselves has hopefully been fixed. Sorry for the late patch and not releasing a quick hot-fix for them. The reason this patch is so late is because I was in the middle of fixing the offsets for the locomotives and I couldn't release an update to the tender without updating the rest of the pack at once. Feedback on this patch is greatly appreciated.

• Fixed a bug causing the light meshes on the Elephant Ears to appear red, a side effect of this fix is that the light mesh now has a different texture sheet
