Celestia Forums

Hi,

on ubuntu 22.04 celestia 1.7 work for a while but systematicaly crash with a:

celestia: ./src/vcacheoptimizer.cpp:173: void meshopt_optimizeVertexCacheTable(unsigned int*, const unsigned int*, size_t, size_t, const meshopt::VertexScoreTable*): Assertion `index_count % 3 == 0' failed.
Aborted (core dumped)

Any idea?

Thanks

Build without meshoptimizer.

Hi,

I will try.
I see that it is linked to the fact that I add by hand orbit and attitude of a spacecraft. (.xyz and .q files)
If I remove this spacecraft this problem disapear.
My orbit and attitude were working on celestia some years ago. Was something changed in those formats?

Thanks

i do not think that .q files are an actual format supported by celestia

.q files are used for determining SampledOrientation, but I do not know how to use those
