Default .fx files not loading in DirectX shader (3ds max 2020)

[Anonymous]

Hi Guys, I am trying to learn from the existing .fx files (C:\Program Files\Autodesk\3ds Max 2020\maps\fx) how they work. However, except for 'StandardFX11.fx', none of them load correctly.

All files give me the following message:

To get more information, define the environment variable OGS_WARNING_LOG_ENABLED to the value 1, restart 3ds Max and check Max.log in the Network subfolder of your 3ds Max User folder, it should contain the parsing error.

What is going wrong?

Most of the times , at least on my end this problem is fixed by going to Customize-Preferences -Viewports and change the display drivers from nitrous direct3d 11 to nitrous direct3d 9 . Hope this helps !
