Making Slabs?

@Kreator your welcome, I also got a working slab model using MrCrafish.

@Theepicshark, I have noticed in the previous comments that you used MrCrafish and still was looking for answers. I had a problem with it too, until I saw in the program that the scale was in pixels. Amending to what @Charlie said in the previous comments, the scale in the MrCrayfish program should be x=16 y=8 z=16. The Block Dimensions in MCreator should be x=1 y=0.5 z=1. Even though the inventory image looks weird, this is the closest I got to an actual slab if your still looking for an answer. Also, I think the version of MCreator plays a huge role on how things are done. I'm currently using the latest version (1.8.1) if that also helps.

mcreator should have slab and stair options, if you ask me

I figured Out A simple Solution to this problem:

#1 Create A .json model of a slab and import it into mcreator 

#2 Create Two Blocks For Your Slabs, the Half Slab Using The .json model and the double slab.

#3 When Creating The Double Slab make it not drop itself but drop to half slabs instead

#4 on the half slabs procedure page create a procedure from "on block right click"

#5 in this procedure you want it to look like this.

Event trigger - triggered by external call 

or when (global trigger):    No additional trigger

        if     -     Has provided entity     'your slab'    in inventory

do     -      if - Has provided entity     'item in entity's main hand'    in inventory

         do      -     Swing main hand of entity

                         place     'Your Double Slab'    at x:   x   -   y    -   z

                         play at x:   x  -   y   -   z   level:   1   pitch:   1    sound:    block.wooden.place

The Only Problem With This Method Is That You Can't Place an upper slab down :(

WARNING! When creating the half slab make sure to set Max Y Cord. to 0.5

I heard a YouTube user going by the name User of Bricks explain and discussed this topic on his channel but sadly he only made the slabs for his own mod for Minecraft called travelers Adventure, travelers tales? is some mod names like that so i believe the only possible way to create slabs + double sided blocks aka double slabs is to extract from his modification and creating them that way i'm stumped at too how slabs just can't be created using MCreator because i was making a dirt slab from my Mod Mo' things (Which in the Minecraft itself is titled More things mod don't ask why the r and e isn't off the title) and i was very confused as to how you can make the model for the mod object i may have found the fix though you may need have the block based base off the slab model thts how this can eb fixed
