Short description of error
Just realized the Film and RRT view transform presets are missing in this latest build, along with all film looks. Also the basic contrast presets for "Look" are only available when Filmic or Standard is selected. I'm using the Film preset for a current project, so I will need to roll back to the previous installed build until this can be fixed. Thanks!

Oh okay, thanks, Brecht, for letting me know. I'm able to match Filmic to the old Film preset using 1.2 exposure and 0.5 gamma, but of course it misses that extra warmth the Film preset had. On the plus side, Filmic has more accurate color than Film did. I guess if leaving legacy transforms in would break something, then I'll just need to move forward without them. Thanks.

Well I'm going to chime in once more on this, Brecht, having worked with the two competing view transforms this past week. My client actually preferred the look of the Film preset (over Filmic), so that has me staying with a older 2.8 build for now. I really think the legacy presets should stay in right until the day that they can be replaced with updated versions that work with HDR. After all, why should HDR be a factor in taking away an artist's creativity? There is tons of content being made that has nothing to do with HDR. The more LUTs and grading options we have, the better. Let the artist decide if the presets will work for them or not. Otherwise, we're forced to use a stripped down version and try to recreate those classic legacy looks using color curves, exposure and gamma settings, and extra post processing when we shouldn't have to. The presets just worked before. Unless they explicitly break some new feature of Blender, I say let them remain. :-)

Thank you!

James Austin (James9856) reopened this task as Open.

What in the h3ll is the point in removing these? Is there something about them that's broken?

I just wasted 11 hours of rendering BTW.

Color management isn't applied until you save the image and it's not applied on EXR. You could've saved it as EXR, and applied the color management to that image later, to not have to re-render again

Yes, it's very unfortunate these presets were removed. I'm still using 2.80 (sub 69), branch: blender2.7, commit date: 2019-05-17 23:36, hash: rB03672e77836d which includes a few bugs that were fixed in later versions, but at least this earlier build allows the artist full creative freedom. Hopefully we will see the decision to remove the presets reversed soon. It certainly would be greatly appreciated by many in the Blender community and aid in backwards compatibility with older Blender training out there.

@Adam Janz (Copperplate) While it may be more work, you still have full control over the result by color grading in the compositor.

That is true, Robert, but trying to manually match the gamma response of certain presets is not something artists should have to do when we had something that worked perfectly fine. Again I say the presets should be retained until they can be replaced with HDR capable ones (although HDR is not something that is important to me).

I think i've managed to cheat the system by copying the 2.79 colormanagement folder and replaced the 2.80 RC1 giving back the film color settings. It seems to work too. Nice dynamic programming!

Yes it has definitely done the job! :)

Nice find, James! So you just swapped one folder with another? Would you mind sharing what these two folders were named? Thanks (Now we're a bit like the MagicLantern team bringing advanced functionality to their Canon DSLRs that Canon omitted...) Hey I'm not against the Blender devs making changes, (they've made some pretty incredible ones which is hugely appreciated by me!) but as the old adage goes... if something's not broken, don't fix it... :-)

I renamed the current 2.80 rc1 colormanagement folder to Xcolormanagement.
See my unzipped folder in image below...


Copied the 2.79 folder from C:\Program Files\Blender Foundation\Blender\2.79\datafiles\colormanagement -> see folder mentioned above.

Great; thank you, James! I will have to give this a try... :-)

So I tested the folder swap in RC2... you only get access to the film looks, but you do NOT get access to the "Very Low Contrast" to "Very High Contrast" settings, which is what I need if I'm using the Film preset. So I will just stick with Filmic until this is changed back. If I do need to render Film, I'd have to use an EXR and then open it in an older version of 2.8 in the compositor to apply the Film preset.
