modules.cfg:
decals_art=on

https://docs.mastercomfig.com/en/latest/customization/modules/#map-decals

What is the context of this happening?

modules.log is used for the in-game selection, but does not affect modules.cfg. Can you share your modules.cfg?

Also, the reason why it says that error is because in a recent update, TF2 broke how in-game selection was being done. I fixed this in a mastercomfig 8 beta update.

What version of the config are you using? Also, you can use the normal way to select modules, in modules.cfg. Do not use the =textures=high type commands in cfg files. Use textures=high in modules.cfg.

mastercomfig 8.0.0-b11
https://cdn.discordapp.com/attachments/389091098922057728/633377038002028555/mastercomfig.zip

* Reverted experimental networking changes
* Disabled custom occlusion settings (experimental change, please benchmark vs. b10)
* Updated the localization files

CS:GO has much more restricted options than TF2, yet it's a huge esport. The only thing that's really killing the competitive scene is the lack of a Valve backed tournament. Money shifts a lot of things around and makes people able to ignore annoyances.

Sure, we could also have some optimizations to the game like CS:GO has had, but really just a Valve tournament would be enough.

I've considered it, but I don't think I'm ready to contact them yet. I'm still not sure about a lot of the options.

mastercomfig 8.0.0-b10:

https://cdn.discordapp.com/attachments/389091098922057728/630059882250240010/mastercomfig.zip

* Removed lod=very_low
* Rescaled lod=low and lod=medium to account for this
* More experimental networking changes
* Rescaled networking rate to account for buffers
* Finely optimized shadows
* Optimized temp ent collision
* Increased the size decals will disappear at
* Optimized ragdolls=high
* Fixed in-game modules selection system to work after update
* Cleaned up some useless settings in the config
* Updated the localization files

Changes from 8.0.0-b9:

* Ragdoll optimizations
* Minor adjustments to increase performance in various modules
* Experiment with optimizing animation load

You all need to read the docs! :D

For your class config issue, custom configs: https://docs.mastercomfig.com/en/latest/customization/custom_configs/
For your killfeed issue, modules: https://docs.mastercomfig.com/en/latest/customization/modules/

But I'd recommend using low, not very low if you want to enable HUD stuff. Because then you aren't the target demographic for very low, which is for people who are incredibly desperate to turn everything off.

3 updates in one day? POG CHAMP

This was a typo in the config settings and is fixed in the updated 6 versions or the 8 beta, sorry. I've deployed a hotfix to mastercomfig 7 to override these settings. You should get it if you apply the config again.

Addons override modules and presets.

mastercomfig 8.0.0-b7:

https://cdn.discordapp.com/attachments/389091098922057728/622854214497992734/mastercomfig.zip

* Fix r_drawropes and dsp_off being improperly set
* Updated the localization files

I've opened up commissions in addition to regular donations: https://ko-fi.com/mastercoms/commissions

You can request me to design a custom config according to your computer, and your personal quality vs performance preferences.

Additionally, as an addon, you can get help from me to do advanced scripting in your config, within reason.

It is so fun to play. Everything feels great, weapons are unique and interesting, and the story is pretty good so far. The quality of life improvements are so good, and like 99% of the cosmetics are in-game rewards.

mastercomfig 8.0.0-b6:

* Removed Bad CPU addon. The base config is now optimized enough for these CPUs as well.
* Cleaned up Very Low preset
* Adjusted packet size and compression thresholds for enhanced reliability
* Changed lighting=low to make world lighting not as dark
* Bumped up ultra modules across the board to use more costly, minor quality improvements as well
* Enabled post process pass combining always to simplify config logic
* Disabled gameplay checks for stats, so community gamemodes track stats

mastercomfig 8.0.0-b5:

* Improve performance on props_high by enabling static lighting for props
* Increase packet delay limit from 30ms to 60ms
* Use dxsupport cvar values in cfg. This fixes many issues where people were not getting full performance benefits out of their modules, or were not seeing the effects of their modules properly applied.
* Added -gl_enablesamplerobjects and -gl_texclientstorage to OpenGL launch options. These options can improve texture management, and reduce memory usage.
* Mastercomfig automatically enables ropes for official Mannpower maps
* Removed cvars that were setting to default, reduces file size
* Disabled cl_showpluginmessages since the TF2 default was changed intentionally from 1 to 0 a year ago
* Enabled net graph solid ticks (like TF2 default, comfig default was improperly set to 0)
* Added early particle removals to Bad GPU. These cost time to check on the CPU, but are worth the GPU particle rendering savings on bad GPUs.
* Fixed a bug where the server could disable prediction https://github.com/ValveSoftware/Source-1-Games/issues/2618
* Removed packet_size=lowend completely
* Improved documentation and fixed typos
