Does the engine allow for use of external shaders?

If it does not, does it support deferred shading and SSAO? (or an editable pipeline for that matter)

Thank you.

Hello,
Because of significant amount of optimisations, currently only builtin shaders are supported.
And yes, Deferred Shading and SSAO are already present.
If more shaders will be needed please write on the "wish list"
Thanks

This perfectly suits my needs atm.

Thank you
