Hello @ all guys,i’m making some blueprints and i need to change the blueprints option in the left menu,and i can’t see option,can you tell me why or how can i see option?
I need to know for going farward!
I got ue 4.3 so it’s all updated!
Thanks you. <3
Do you mean “Blueprint Options”? If so in the toolbar there is a button to called “Edit Blueprint Options” that will open up the options in the details panel.
Or do you mean an option is grayed out and not editable? If so try compiling the blueprint. If that doesn’t help (for example you are trying to change a variable type), you will need to delete all instances of that node from your blueprint before you are allowed to switch the variable type.
Or if none of helps, can you provide a screenshot showing what you are looking for?
ps. thread will likely be moved by a mod for you into the appropriate forum topic, but if you have any questions regarding blueprints in the future, please post them into the into the Blueprint Visual Scripting forum topic, the Work In Progress forum is meant for showing off your work, in progress. 
Welcome to the forums! 
If I am understanding correctly, you’re trying to find the ‘Spacing’ setting shown in the example at the bottom in your example at the top?
The Spacing option you see in the bottom example is based on settings added to that specific blueprint and then made to be editable. Just guessing here, but it looks like is a BP that aligns a bunch static meshes along a spline. What is shown in the Default section of the options is a variable (apparently a float) called ‘Spacing’ that drives some sort of functionality in the event graph (likely the construction script which allows the in-editor settings to be adjusted). When you create a variable, you can click the little eyeball icon next to the variable name. will reveal it in the options section when you select a placed version of that blueprint in a level.
Just creating a variable and making it editable will do nothing other than letting you see and adjust the variable number in the options. To make it doe something you need to create the nodes to do something with that number. From looking at your second screenshot, I imagine that the construction script of blueprint is set to look at the number set in the spacing variable and uses that to decide how much space is between each spawned mesh on the spline. You can dig through the content examples to see how exposed variables like are used. I would also recommend checking out the great ‘Intro to Blueprints’](Introduction to Blueprints (pre. v4.7) - YouTube) videos Epic has on their YouTube channel for more in-depth examples.
Hope that helps.
Ah ok, I see what you mean now. When following the Spline Road Tool tutorial by (I have done the same in the past), you need to go into your spline blueprint graph, and on the left panel make sure the “Spacing” variable is set to “Editable”, as shown in the image attached below. After setting it to editable it becomes visible in the details panel after you compile/save the blueprint. After that it should be there for you.
Hey bros you saved my life so i can go on with tutorial!
Thank you so much!
