Gsplats and meshes with transparency

Help & Support Gaussian Splatting
1

Hey there, Im experimeting with gaussian splattings using the playcanvas engine and I want to use transparent meshes above the gsplats to highlight certain areas.

I found out that meshes and gsplats dont play nice together with meshes becasue of sorting and transparency.

An idea would be to create a invisible mesh volume that has a simplified shape as the gsplats and have this to occlude the meshes.

Is this a normal practice with gsplats? Are there examples about this?

Would love to hear anything related to this and how to solve it.

One options is to convert your transparent meshes to splats and use those. We have some scripts and also two examples - all you see in those are generated from splats:

to fake transparent meshes, you could also use dithered transparency that writes to depth buffer and so works fine with splats: PlayCanvas Examples
