Fusion in Resolve issues (or limitations?)

PostWed Aug 15, 2018 11:53 am

I've loaded 2 multi-pass exr sequences into Resolve and onto my timeline. I jump to Fusion on the first clip. It has the mediain - mediaout nodes. I have to dupe the mediain because I'm separating out my passes (dif, refl, spec, ao). Then then grade/merge, do stuff, connect to media out. While looking at the console I see a bunch of errors:

Merge1 cannot get Parameter for Background at time 237. Shape3D1 cannot get Parameter for Material at time 237. Poperouter1 cannot get parameter for Input at time 237, etc. It appears everything "looks' ok in the viewer. Is multipass exr broken or slow in decoding in Resolve which is causing these issues?

I also hope some thought is put into autonaming option on the mediain nodes to something more useful. Even drag/dropping clips into Fusion from the media pool nets a "mediain" name. I know we can rename (F2) but hopefully in the future this can change.

A separate issue is, in Fusion I do an Alembic import of a scene with multiple cameras. I work on that shot. I go to the next shot in Resolve and go to its Fusion tab. Resolve won't let me drag/drop the .ABC file from the media pool into my second shot. I have to go into the first shot's Fusion Tab and copy the alembic data, then go back to the edit to select the second clip, then click on the Fusion tab to finally paste the alembic data. This doesn't seem too efficient.

A gotcha:
I also noticed you are forced to make your decision about your project in Resolve up front with regards to frame rate). I remember that from using Resolve but forgot about it when using my Fusion mind-set. If you screw it up and start working on a Fusion comp and realize the frame rate doesn't match your render sequences or clips, you cannot go back to your project and change it. You have to start over. You can't even save out a fusion "comp" to reattach to a clip later on? Which that seems to be a big gotcha too.. unable to create "fusion templates" which can be exported/imported later, without possibly finding a way to import a fusion project into a fusion project, selecting a clip and then jumping into the fusion tab to do a copy/paste into another fusion tab on another clip.. you see how strange this seems?

BUG:

Multipass EXRs and the Loader (mediaIn node). When you bring in a multipass exr and designate specific channels for RGB, it doesn't save/retain those settings beyond the session. For example: Changing R G B channels to use Diffuse.R, Diffuse.G, Diffuse.B from the EXR. Exit Resolve. Reopen project. the mediaIn node for the exr reverts back to RGB.

It's a dealbreaker here.

I experienced the same issue with my alpha channels when setting them to specific buffers. After every new start of resolve and loading the project they are gone. It's indeed unusable like this. Hope they fix this soon
