Change model overtime

I’ve got a model of a sapling and a tree i want to change from the sapling to the tree over a certain time to simulate growth. Any help would be appreciated

just do a BP like the one in the ss, add a static mesh componnent, drag it to the event and it will ask if you want to get or set, click set, add it on begin play, then add a delay (time to grow) and another set, right click on the static mesh pin and click on “promote to variable” the first one will be the sappling and the one after the delay will be the tree, add the desired meshes in the “default value”

after you put it in the map you

thankyou very much for the help it all makes sense now the only issue i have is it wont let me chose any meshes in the default value ?

Seriously? Usually blueprints ask you to compile the blueprint before choosing the default value, if it still dont work, click on the variable and upload a screenshot to show me what happens
