Fedora 42 and H21 licence issues Sept. 4, 2025, 11:48 p.m.
Hey,
I've recently also run into this issue and solved it by running the following steps:
This installs the necessary selinux policies.
You might also need to check in the license manager if it is still preferring the local license server (over the sidefx server).
Cheers,

## Install SeLinux Policies # sesinetd sudo systemctl start sesinetd.service sudo ausearch -c 'sesinetd' --raw | audit2allow -M sesinetd_local sudo semodule -i sesinetd_local.pp # hserver sudo systemctl start hserver.service sudo ausearch -c 'hserver' --raw | audit2allow -M hserver_local sudo semodule -i hserver_local.pp ## Reboot (or try running) sudo systemctl daemon-reload sudo systemctl restart sesinetd.service sudo systemctl restart hserver.service
This installs the necessary selinux policies.

Mantra Distributed Rendering "No Code Generator Available" Error/Bug Oct. 1, 2018, 4:08 a.m.
Hi,
I am currently trying to use mantra in distributed rendering mode. (mantra -H machine1,machine2)
It all works as expected, but as soon as I connect something into a cached shader (for example a constant into the principled shader), the error “No Code Generator Available for op
shader_path_xyz” pops up and it doesn't render at all anymore. It also happens with custom cached shader assets. All works well in non distributed rendering mode. If I unlock the asset, then it seems to work again, but this is unfortunately not useful in production.
Additional Info:
I am using windows and the “Force VEX Shader Embedding” checkbox is on.
Has anyone experienced this error before?
Cheers,
Luca
