i am using blockprops to make my portal block id 100 a messageblock, but when i type /mb i cant see my newly added block

You can make a block work as a portal or a message block, but not both.

i know i know, thats what i did, i have a block that has a TEXTURE of a nether portal, you get it?

Can you show me the exact command arguments you used?

It looks like you got it working:

i see no Portalblock sorry

i used:

/blockprops global 100 messageblock

/mb

Solution: i used the scope 'level' for blockprops and it works now
