Some character's parts are not affected by the Shadow Weave invisibility

[alexhrosts]

When under the Shadow Weave invisibility effect, the characters become semi-transparent when close to enemies, and to the player themselves. However, following character parts are still visible:

• Pocket's gun
• Dynamo's head
• Viscous' gun
• Internal parts of the Warden's gun

The other 2 I noticed but they seemed somewhat different then the rest:

• Fire aura effect on Infernus' gun hand is visible, the hand itself is invisible
• Magical aura effect on Wraith's left hand is visible, the hand itself is invisible

This is still true at least for Dynamo, but even stranger: you can see Dynamo's head THROUGH WALLS if he is invisible with Shadow Weave but within the detection radius. Although his head will also not be visible through walls sometimes which coincides with his footsteps no longer being audible, even though he is within the detection radius.

Does the game stop rendering invisible people (including their footsteps) within the detection radius under certain conditions? If he's near a corner (instead of more deeply on the other side of a wall) then I am more likely to be able to see his head (through the wall) and hear his footsteps.
