Place a ignite filter on a clip in resolve and you'll see the parameters for that filter in the openFx window as expected. However, apply another ignite filter after that and you'll find no filter parameters for that filter or any other subsequent filter after the first one. I'm using the free version of resolve but am using the latest version. I'm on a iMac pro loaded with 128gb ram and the ATI Vega 64 graphics card.
Anyone else seeing this issue?
