Hi Slayer1918z
1. If your textures look blurry/low-res you need to enable anisotropic filtering on your video card. I recommend a minimum of 4x AF. If you are referring to the greenish hue in some textures the update will include some textures being replaced as 24bit rather than DTX5 compression.
2. This was purposefully done so that you only see the run anim when the gun can not be fired. The SAW is set to only be shootable when walking or idle and so you see the run animation whenever you are running regardless of having ammo or not. You have the option of editing the gunspecs to allow run animations to play when the gun has ammo by uncommenting the ;//run=x,y setting.
You can also restore run and shoot for the SAW, or automatic reloads in gunspec by editing the expanded settings.
3. Project Blue and other mods will require an update to the new source after 1.18 is out of beta if the authors wish to support all functionality.
4. PB handles transparency of crosshairs differently. Open the crosshair and add an alpha channel that's all black and re-save with alpha channels. That should fix it.
No problem, if you have further bugs to report for MP53, please do so
here.
