Hi,
I guess that is a but, but after changing the animation curve from the default to “Linear”, it messes the animation completely.
In Blender looks great, after exporting it is just doing random stuff! if i keep it in “Bezier” it looks as it looks inside Blender.
tried also older versions of Blender, not a fix. Is anyone having this issue?
regards

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.

webenart.com2023-04-30 at 8:16 pm #63372xeonCustomerI actually had the same issue and sent it to S8S and got the following response.
“Unfortunately this is not a bug, but a limitation of glTF format which can’t store Euler angles (only quaternions). Basically, the 0 and 360 rotation is the same, so the cube is motionless. To make it work you need to supply a couple of intermediate keyframes in-between.
In the future we might consider developing some non-standard extension to glTF to support such cases.”
I tried adding additional key frames and it just doesn’t work. So just have to manually adjust Bézier curves.

In fact it’s a working solution. With four keyframes (0°, 120°, 240° and 360°) rotation works as expected with the linear interpolation.

With three keyframes it also works but in the opposite direction…P.S. In one of my old apps, exported somewhere between 3.5.0 and 3.9.0, cyclic linear rotation works properly with just two keyframes Now, if re-exported in 4.2.0-4.3.0 it doesn’t work )))

2023-05-01 at 5:59 pm #63379xeonCustomerUsing Blender 3.4.1 and Verge3d 4.3.1 you may find that after deleting the linear rotation keys that are causing a problem, the object still will not animate properly preventing even translational animation from working correctly in Verge3d 4.3.1. More testing needs to be done to see if replacing the keys, effectively over-writing the keys with new info will work but deleting them will not.
Like KDV has mentioned older files created with older version of Blender and Verge3d are working without issue and do fail when brought into 4.2 or 4.3.

2023-07-18 at 10:11 pm #65325xeonCustomerits an option for some but for those that dont want to add additional keyframes there are alternatives.
