Please add a button to add a new blueprint parameter variable

[undermark5]

Another +1 from me. Fortunately there is a out of game solution for this and that is manually editing the blueprint string and reimporting it. The strings are base64 encoded gzip of a json string... Using this it's possible to add an extra parameter to the blueprint regardless of whether or not it's got a corresponding value in the blueprint itself. I'm not exactly sure how this plays with selecting new contents, but it is useful and seems to already be supported by the engine, just no way to access in game.

There was a bug causing two parameters with the same default value to collapse and use input value of the later one, not sure if this is fixed. (Edit: 117127)

Not sure what the bug you're referencing has to do with way I pointed out to add extra parameters to the blueprint via editing the string...

If you add parameters via editing string, and those parameters would have the same default value, strange things may happen.

+1 Support from me as well.

I support this proposal.
My use case is that, in a book full of parameterized blueprints where you select the result of a recipe (e.g. to turn iron plates into gears, you click on the gear recipe), I want to add a blueprint that uses a furnace to turn e.g. iron plates into steel, but the "iron plate to steel recipe" isn't available. I'd have to parameterize my blueprint around the input instead, and then click on iron plates when placing the blueprint, which is less intuitive, and confusing in the context of the other blueprints in the library.

It's sad that many proposals don't get a response by the devs and that most proposals aren't even implemented.

Edit: (This post was merged from the duplicate thread.)

Note that you can safely delete dummy entities with the extra parameters if your blueprint is stored in your library when you do it (inventory does not work). See 124439.

But I agree that there should be a button in the UI to add a dummy parameter.
