3DGS models exported from Momentum-GS are missing attributes when rendered in SuperSplat, how to fix it?

[KAI6603]

Hello, I have some problems with the 3DGS model obtained using Momentum-GS. The exported model shows the following attributes are missing when rendered using SuperSplat (you can list the specific missing attributes). In addition, I tried to download and render the model file you provided, and encountered similar problems. How should these missing attributes be supplemented? Or are there specific settings or tools that can handle these files correctly? Thank you very much for your help!

Hi @KAI6603,
Our model is not a standard GS model. We use a hybrid representation, similar to Scaffold-GS. The stored model point_cloud.ply contains anchor points, and the Gaussians are decoded on-the-fly based on anchor features and view position, which might not be compatible with SuperSplat. For visualization, you can refer to Scaffold-GS's SIBR viewer.

Regarding this:

In addition, I tried to download and render the model file you provided, and encountered similar problems.

Could you provide more information, such as a specific error screenshot? Using our code to render images should not result in missing model properties.
