Rigidbody instantiated on very fast moving object

Hello everyone, i'm having a problem on pooled rigidbody projectiles on a very fast moving object. If t stay put and shoot everything works fine: the projectiles shoot far away and hit their target but as soon as i move quite fast or fall the projectiles fly away backwards or upwards respectively. How should i fix it ?
Should i leave the physics behind and code it differently or is there a proper way to fix it keeping the physics intact ?
THX a lot.

 

make sure you reset the velocity/torque/rotation to zero for pooled projectiles when you return them

 

JamesLeeNZ, thk you very much for your answer, i will certainly make sure of that, though it seems the projectiles fly away even the first time i use them, according to the speed of the vehicle.

I found a solution by symply cranking up the projectile's speed (which was ignoring my tag or object collisions at that speed) and deactivating a lot of the the layer collision matrix in the physics project settings to be able to get my collision detection back ;-) !

 

fair enough. Always hard to know for sure without knowing full details of forces etc. I was considering you may need to add vehicle speed into force, but Ive never had to do that myself
