There's a bit of transparency in the lion head, is that an artifact of the splat itself or the renderer?

It is an artifact of the model I believe. I did notice that as well.

Gaussian splat models are fairly imperfect on average.

I don't know if the splat is exactly the same, but the playcanvas engine has no false transparency on this one: https://superspl.at/scene/7e4e9bcb that splat is actually of fairly high quality, so unless this is a materially different splat (with some of the gaussians dropped out maybe?) I'm inclined to blame the engine.

If you turn off performance mode this is way higher quality than either of the other two versions of this model linked by bhouston in this thread, although with a much lower frame rate on my phone of course:

I took it from here and I do see false transparency:

There is even a link in the ThreeJS example preamble to this scene. I didn’t realize there was multiple lion splats of the same scene flying around.

Tnx!
