TTL Flash + basic triggers

if I am going to use a basic trigger on a TTL activated off camera flash using my camera with a trigger, what will happen with my flash exposures?

Thank you

Basic triggers imply all manual flash so the flash will be triggered properly but at the power they are manually set for. No TTL is available, at least for Pentax. You will need to test and adjust the flash power manually.

Since your other thread got closed:
FEC will not change anything on an off camera flash. The trigger will only send a 'fire' signal, no TTL info is sent. The flash will fire at whatever power is manually set on the flash.

And if your flash does not support manual power level controls, then you will have to adjust the exposure by changing the lens aperture, or using other tricks like putting gel filters over the flash.

Some flashes can be operated in an Auto mode which can help, depends what you have, and how you set up the shot.
