While i was building, i noticed that the shadow of players wasn't renderring when standing on a chiseled block :

I also tested it with other entities, a pig for example, and the shadow also didnt show up:

(This happens on both full chiseled block (16x16x16) and partually chiseled blocks (example: 14x10x6). The partual chiseled blocks i can understand, but not for the full blocks)

• MC Version: 1.10.2 (Forge-12.18.3.2254)
• C&B Version: chiselsandbits-12.12
• Do You have Optifine: No

Shadows can only render on block states marked as "isFullCube" so this only will work with full blocks, but it will work.
