change block model of full opaque block cause render error

With the new models, you can't (shouldn't) make solid opaque blocks not full or not opaque.

Implments in this way makes model useless,
since most of blocks in mc are full opaque.
even we make new model bigger than original.
it will still not work.
since the mc clip the face by direction.
the face exposed outside will still be clipped.

And

bug report is
a feature didn't work as it intends to, though the doc didn't say we can't do that.

feature request is
a feature tends to work in this way, but we want to change it.

as mojang didn't say that limit.
I think it is a bug.

Could you please rewrite your answer and look for spelling errors.
And you shouldn't use models for making a full opaque a not full opaque block.

Still in 14w17a. But I agree with Samuel.

This is quite intended, because Mojang doesn't support non block shaped models.
Round tree logs in Minecraft ? That's not Minecraft.

It's actually created by blocks.
Just with some rotating

Well don't do that, then.

Seems like it would work better with something that starts out smaller, like a modified cobblestone wall (the single version).
