ToneMap settings greyed out, encoding with ToneMap enabled fails

[damian101]

Avisynth is Windows only. (gave up on supporting it through wine on Linux&MacOS, too much hassle)
Vapoursynth works fine on Linux and MacOS.
I wrote scripts for Ubuntu to build and install Vapoursynth and the plugins Hybrid uses (see: https://github.com/Selur/hybrid-vapoursynth-addon).
The scripts Hybrid uses are available under: https://github.com/Selur/VapoursynthScriptsInHybrid/
Otherwise the user is required to:
a. build/install Vapoursynth
b. build/install the Vapoursynth filters Hybrid uses
c. let Hybrid know it should look for Vapoursynth (misc.ini + vapoursynth=true see: https://forum.selur.net/thread-10.html)

I checked the source code, there is no code in Hybrid which would disable the "useToneMap"-button.
My guess is that this is some incompatiblity between Qt and the theme you use. Try whether changing the style of Hybrid (Config->View->Style) does change whether the button is greyed out or not.

Cu Selur

I have Vapoursynth installed, have some Vapoursynth plugins that Hybrid can use installed, and created a (confirmed to be working) misc.ini file with entry vapoursynth=true. However, the Vapoursynth tab is still not there. Do I need to do something with the Hybrid Vapoursynth scripts (https://github.com/Selur/VapoursynthScriptsInHybrid)? I have no idea what to do with them.

The ToneMap button is indeed never greyed out, only the settings are, as can be seen on the screenshot. Changing the style does not change this behavior. When disabling ToneMap I get an error message: "FilteringModel get->found no field useToneMap".
