Mostly unrelated: Don't implement ITileEntityProvider, the Block class already has the methods hasTileEntity() and createTileEntity(), please use those as they have IBlockState as parameter instead of the metadata.

To be more specific

createTileEntity(IBlockAccess world, IBlockState state)
hasTileEntitity(IBlockState state)

I'm trying to create a jar of sorts with one section being translucent and another part being opaque. The translucent part works fine, but from some angles the opaque section disappears.  Any tips?

I noticed you have getBlockLayer(...) set to translucent, what are the other options there as i do not remember (no IDE or code ATM).

I didn't see that detail but I would always return cutout mipped as not the complete block is translucent. That may even fix the problem.

Hi

 

Translucent rendering is always a problem because the appearance of your model will change depending on which order the faces are drawn in (and which angle you're looking at the model from).  I think that's probably what is happening to you.  Usually, you should draw the opaque faces first, then the translucent faces second, and I don't think the block model guarantees that. But the same problem applies to translucent faces as well, i.e. if you look through one translucent face and see a second translucent face.  In order to get it right you usually have to depth-sort the faces.

This link explains it a bit better

https://www.opengl.org/wiki/Transparency_Sorting

 

I've implemented a jar similar to yours before (admittedly before 1.10.2), and I used a TileEntity to do it.  The opaque parts I drew with a block model, then in the TileEntitySpecialRenderer, I draw the transparent faces in depth-sorted order.  It worked but was pretty complicated and you would have to understand quite a bit about how depth buffering, culling, and depth-sorting work.

 

Cutout_mipped is something different and will make your translucent panes go non-translucent.  BlockRenderLayer.TRANSLUCENT is correct but is not enough.

 

If you find a simpler way please let me know..!
