Hey @JW3153 ,

Just got word back from the team.

It has been fixed, so you will need to update the project from the launcher.

Let us know how it goes!

Thanks.

Hi @LizzySphinx

Thanks for having the team look into this.

I can confirm that this issue is now fixed, though, there seems to be something different from a render quality perspective to the old version. This version seems very noisey and just not quite right compared to the previous version when opened in 5.6.

Having said this, the problem I OP’d about is definintely fixed, and I’m sure the increase in perceived noise in the scene is due to a render setting somewhere from the updated project.

I’m sure I can find and fix that myself.

Thanks again!
