Changing spherical harmonics degree on gaussian mesh

Questions
1

Hi, is there a way to change the shDegree on a gaussian splatting mesh after is loaded? In some cases, a processed gs model with level 3 may have some visual artifacts and it’s better to display it with level 2. Also on some old devices it seems to perform better a model with 2 levels of sh instead of 3.

I’ve seen the gs mesh has shDegree porperty but it’s only a getter.

Thanks

Yes, it’s only a getter. There is no way to change the SH degree for now.

My favorite LLM tells me it “just” needs to discard SH coefficients for high degree SH. So, it should be possible to do it at runtime. Let me check that.
