The bug
Some entities are rendered black if there is no light near them. This can be easily reproduced in the End.
Affected entities (1.11)
Minecarts with
DisplayTile
, such as hopper minecartsWet wolves
Primed TNT
Code analysis
Based on 1.11 decompiled using MCP 9.35 rc1
The renderer of all affected entities call the method net.minecraft.client.renderer.BlockRendererDispatcher.renderBlockBrightness(IBlockState, float)
.
Can confirm (see screenshot), and in case anyone else wants to confirm it, you'll need this code for spawner minecarts (note: /give will not work):
