I have a resorce pack that I created.
I resently updated to the Minecraft version 1.9.3 Pre-Release 1.
The texture is working exept for some blocks:
Wood logs (put on the side)
Hay Bale (put on the side)
End Brick Pillar (put on the side)
The texture of these placks are not showed. I don't have a texture for these blocks in my resorce pack so I tried to add. It didn't fix it.
I attached my resorce pack and two pictures, one with my resorce pack and one without it.
EDIT:
Problem solved.
This is an issue within the resource pack itself, update/correct the blockstate files.
My resource pack doesn't have them included, and it works fine.
