ResourceLoader creating too many jobs and crashes

[mbalajee]

⚠️ Issues not using this template will be systematically closed.

Describe the bug ResourceLoader creates a job for each primitive to compute tangent. This crashes filament when loading a larger model, even on Pixel 8 (which has been the best case device from our testing on various models).

Computing tangents for all primitives in a single job works (no longer crashes) but I guess that's not ideal, jobs can run in parallel ? So may we run them in batches to avoid creating way too many jobs?

To Reproduce Steps to reproduce the behavior: Load a model with 50+K renderables

Expected behavior ResourceLoader#computeTangents shouldn't crash

[poweifeng]

Do you have the crash log?

And an example gltf would definitely be helpful.

Added logs in the description. Will try to get a test model that i can share here

[mbalajee]

@poweifeng here is the test model

[pixelflinger]

@poweifeng FYI we currently have a limit of 16384 jobs -- we should probably not create that many :-)
