Hi,

That was fixed since Clarisse iFX 4.0 SP5. If you open an older project make sure that the Fresnel Energy Conservation attribute of the standard Matetrial is checked.

Welcome to the community !

Cheers ;)

Hi,

You did not fix the issue. By changing the IOR to 1.0 you simply "turned off" the reflection of your material. Technically, you still have reflection but this value results in "cancelling" the F0 fresnel reflection. Your shading will look incorrect.

The only way to fix the issue is to update to Clarisse 4.0 SP5 as Démian mentioned.

Yes, buddy, even I was thinking the same 4.0 would still be needed.
