architectural doubts clarification

hi friends i am new to unreal engine and i love the architectural works . my doubts are

1- is it possible to create a architectural walkthrough without coding .
2- is coding necessary to create an intractive walkthrough which can be viewed in tab ,mobile ,otherdevices .

pls help me friends since i am new to the software !

Hello

1 - Yes
2 - No

Its answer to your question, but if you want interactivity like opening doors, turning on/off lights, changing materials, it also could be done with little or no at all of coding…

thankyou so much ! can u help me with a link on how to creat a walkthrough and how to create intractive walkthrough .

Just watch the hundred/thousands of tutorials on YouTube on interactivity and you’ll find what you need there, since is explained quite well.

For developing on different platforms the docs are your best friends, take your time and read the technical stuff there and you’ll see what you can and can’t do.

If you just want to do a walkthrough just create a project using the 3rd person template as a starting point.
