Well I have never seen any reference relating to the impact effect of objects with shields up.

I'm sure you all have seen lines like this

ImpactEffectSoft = "com_sfx_ord_exp"
ImpactEffectRigid = "com_sfx_ord_exp"
ImpactEffectStatic = "com_sfx_ord_exp"
ImpactEffectTerrain = "com_sfx_ord_exp"
ImpactEffectWater = "com_sfx_watersplash_ord"
ImpactEffectShield = "com_sfx_ord_exp"

Well unfortunately that last line. Unfortunately, it seems to take no effect on the impact effect that plays on the shields.

For example, if you provide a vehilce with a shield, it wall always play the com_sfx_shieldimpact_sm effect. Even if you change the line in an ord refering to the shield, it will stay the same.

Is anyone aware of any solutions to this?

Rename the effect you want to use to com_sfx_shieldimpact_sm?

Otherwise, I dunno.

The effect com_sfx_shieldimpact_lg and _sm are both in data_ABC/common/effects, you could try editing them, I tried but I don't think it worked.

But you could try.

I actually did change the shield effect once, so there is a way to do it. But unfortunately it's been so long that I can't remember how I did it or where the odf is that has it, sorry.

But you're certain you edited an ODF to get it that way?

Pretty sure, like I said, it's been awhile, 2 or 3 months since I did that.
