关于在Forge Viewer中显示3ds Max动画的技术问询

Hey there! Great question about bringing 3ds Max animations into Forge Viewer, especially since you're familiar with how Fusion animations work. Let's break down the current state and what's available now:

Current Capabilities & Recent Updates #

Good news—Forge Viewer does support displaying 3ds Max animations, and recent improvements have brought it closer to the smooth experience you get with Fusion animations. The key is getting your 3ds Max content prepared correctly and using the right workflow.

Step-by-Step Workflow #

• Export from 3ds Max Properly: When exporting your animated scene, stick to formats like FBX or USD (USDZ works too) and make sure to enable animation-related export options—this includes checking boxes for keyframe animations, skeletal animations, and any object transforms you want to preserve. Skip overly complex non-standard animations if you can, as they might not translate perfectly.
• Convert with Model Derivative: Use the Forge Model Derivative service to convert your exported file to the SVF2 format—this format has far better animation support than the older SVF, so it's essential for smooth playback.
• Load & Control Animations in Viewer: Once your model is converted, load it into the Viewer just like any other model. You can then use the viewer.loadAnimation() method to load the animation data, and use the built-in animation controls (play, pause, scrub through timelines) just as you would with Fusion animations. The Viewer's animation API works consistently across supported formats now, so the experience should feel familiar.

Limitations to Keep in Mind #

• Complex 3ds Max-specific animations like particle systems, advanced dynamics simulations, or custom scripted animations might not fully translate to the Viewer. It's always a good idea to test a small sample first to see how your animation holds up.
• Make sure you're using the latest version of the Forge Viewer SDK—updates regularly add better support for edge cases and improve animation performance.
