Verge3D 3.6 pre1 available!

Hi, we have 3ds Max instancing in our TODO list. However I can recommend another method to reduce the size of your scene – asset compression. It works very well for instanced objects, reducing the binary size a lot!

Thank you, Verge3D team. These enhancements are great! I had not even considered using puzzles to create geometry from scratch.
Also, the “on error” callback slot on the loader puzzles will make much more robust solutions.
Thanks again.

Got one error exporting in a pretty simple scene. Got the same error with version 3.5:

Could fix the first issue, with copying the objects to a new scene. Dont know what the issue with the old scene. Even with all objects deleted from the scene I got the above error.

But now I got a new one, which seems to be related to 3.6 pre1. I can no longer export with compression enabled. As soon as I’m trying to export I get this error:

Max restart worked.

Is it possible that 3dsMax constrains arent working anymore in 3.6pre1? I got a simple scene with a group constrained with a lookat to a dummy object. In max when I move that dummy object, the group is rotating based on the dummy position. But in verge nothing is happening, no matter if I move the dummy via verge or I export the glft with keyframe animation to the dummy.
Never mind, seems I got some issues with the scene I’m working with. In a new one its working as expected.

Hi
Yuri

Does the area light affect on loading of the scene?
