Hi,

Red traffic light in the top right corner indicates that there were some errors while loading your scene. You can check these errors by opening the browser console with F12.

I isolated the object that does this error on scale when display it on viewplayer of b4w sdk
Here is my updated image, first is the blender 3dview


And second is the viewplayer when I click the fast preview button


The traffic light show that have some warning, and see that there are 1 warning that say: B4W WARN: non-uniform scale for object BezierCurve

Here is my .blend file link

Please let me know how to fix it

Please let me know how to fix it

You need to Apply scale of the book or set Apply Scale and Rotation on the object, so the engine will do it on export for you. It's a common user misunderstood, you can read about it in our FAQ.

I will fix it, thank b4w team
