# 3D Editor User's Guide ### ### Introduction We have released a much waited feature - Web Editor for 3D Models in Marvin XR. This will help the creators to build WebAR campaigns faster. If you are going to use 3D Editor for the first time, the following guide will help you to make it a useful tool. ### How to use 3D Editor Open any AR campaign and go to 3D Model menu. This is where you can manage your 3D asset for your AR campaign.

At this point, the 3D model is still non-editable. You need to follow a simple step to make it editable. Go to the right panel of 3D Editor and click on **Scene** option (under **Camera**). Scroll down to **UUID** menu and click to adjacent button **NEW**.

You can see the object layers appearing under **Scene**.Click on the first top level layer and start editing. You can move, rotate, increase/decrease model size, add objects, slide, separate layers and many more functions using the 3D editor.

This will render the real looking view of the 3D objects.

Sometimes, due to browser caching issue, you can see the earlier 3D object getting loaded to the new 3D model editor. If you see this, please close the browser and open again (opening in incognito mode will help). If you are using Google Chrome, cleaing the browser cache with Shift + F5 will definitely help.
