Environments Bathroom Tiny

• Added a new enviro prefab called bathroom_tiny_enviro_small.prefab as @Nayris requested. It is around 10 to 15% smaller. Disclaimer : it's really really tiny and will be hard to create a scene at this size.

• Updated the enviro with NGSS2 shadows.

Thank you ( a frikkin' lot ) to @FCG who dropped by and told me about NGSS2 include for Unity. This is a big update, most of my enviros are receiving the update tonight. You won't have to use VAMifier anymore if you do, and you'll get an overall really better aspect of your shadows in the scene for almost the same performances.

Below is a screenshot of Stasis Lab with the update.

Following a suggestion and a discussion with @Damarmau (thank you mate!)...

• New improved PBR shader for reflective materials (which is also made to be ignored by vamifier to keep the GI on highly reflective objects)
• Disabled shadow casting on the shower doors to improve light propagation and make it more realistic

These modifications are especially made for people who wants to use vamifier with the enviro.

• Updated the hierarchy of the asset
• Updated the script with a checkbox enabling wall transparency. This option is not saved with the scene and only exists to ease the creation process.
  
  Collision are kept, only the rendering is disabled. So you can disable walls even if your characters are using them as a support.
