scene view "Filmic" not found #61

Open boegel opened 4 years ago

boegel commented 4 years ago

I'm using a self-compiled Blender 2.82a, but for some reason unclear to me I'm only getting blank renders.

At startup (I'm running command line, in Linux), the following messages are printed:

$ blender -b cubes.blend -o test -s 0 -F PNG -E CYCLES -f 0
Color management: using fallback mode for management
Color management: Error could not find role data role.
Blender 2.82 (sub 7)
Color management: scene view "Filmic" not found, setting default "Standard".
...

I'm posting this here because of the "Filmic not found" mentioned, but it's not clear to me what the exact problem is.

Is tried using this repository, both by adding a colormanagement directory in the share/blender/2.82/datafiles/ subdirectory of my Blender installation, and by setting the $OCIO environment variable to /path/to/filmic-blender/config.ocio, but this only resulted in the first message ("Color management: using fallback mode for management") not being printed, the other two remain.

Any ideas what could be wrong?

Great find. I suspect there is nothing wrong on your side. Blender likely has shifted things that break compatibility.

It is probably another bad idea gone wrong.

Is there anything I can do to help diagnose this issue? I'm seeing the same problem with an older Blender 2.80 installation.

Note that I was already getting this before I started playing with this repository (it's still not entirely clear to me how this repository and the upstream Blender relate to each other).

Well first question is if it is making the configuration not work at all. Blank renders could be a number of things, none of which related to OpenColorIO. If you were getting the issue before, I suspect it may be on your GPU end.

The render "works" in the sense that it runs and takes a while, and it produces a PNG output file. There's just nothing there at all.

I'm seeing this CPU-only too (I'm testing both CPU-only and GPU-able installations on Blender).

How can I debug this?

Start with the default configuration. Does it work? If you are getting renders with the default configuration, and then you flip the switch to another configuration and you get blankness, then it requires changes. I have an idea on what might need changing.

I'm a real Blender noob, I'm basically just trying to get this render issue resolved for somebody else (I'm responsible for the installation, but I'm not actually using it), who provided me with their *.blend file.

Can you elaborate on what you mean by default configuration?

As an update, it works here. No issues.
