Hi @jchrissy,

can you share the TouchDesigner version you are experiencing this with and the TouchDesigner version it is working with again as well as details to your OS and hardware?

cheers

Hi @jchrissy

On a Mac Mini M1, TouchDesigner 2023.12120, switching the default particlesGPU to use a Line MAT would look like the following:

This was tested under MacOS Sequoia 15.2.

Apple is pushing out graphic driver updates through OS updates. You could try to update to latest TouchDesigner first, 2023.12120. Another solution would be to try and update your MacOS version to the latest.

You don’t mention if you are using the default particlesGPU settings or if you did any tweaks. Could you please share a sample?

Thanks,
Michel
