Hey Guðjón, I assume you mean exporting to Viewer? If so, try enabling Export Animations, I believe this is required for parenting to work in some cases, even if you don't otherwise have animated content.
I usually have the autoback option enabled, it's been awhile since I worked with CE, should have paid attention. Oh well, gives me the chance to improve my scene's terrain I guess.
webGL should gain more and more momentum (especially once mobile browsers support it). Afaik both next major versions of Chrome and Firefox will have it enabled by default. other than that, unity sounds best to go with.
The 5600G is quite a bit slower then the 5600X, but at that price you did ok. For the RAM, make sure after installing to go into the system bios and enable XMP so it runs at full speed: https://www.youtube.com/watch?v=orENI_3nHos
For anyone trying to still figure this out try disabling Vanguard. It's an anti-cheat program from Valorant if you have the game installed on the computer. Apparently it messes with the GPU. But doing that would mean you can't play Valorant until it is enabled again.
It's still not fully implemented into every feature in the engine, so that's why you have to enable it with the .ini files, I'm sure they'll have a realtime GI solution fully integrated into the engine as soon as they can.
Havn't used MR in years but as I remember the sky portal transfers light from outside as its source, but there are a few settings to enable: 'from outside' checkbox. And 'Colour source'>use existing environment.
Also, for future reference, to see stuff like this in the modeling viewport hit 'O' and turn on "Enable Deformers". That will show the mesh in it's deformed, AKA posed, state. But to export, yes, you'll need to freeze geo.
You enabled soft selection: https://knowledge.autodesk.com/support/3ds-max/learn-explore/caas/CloudHelp/cloudhelp/2017/ENU/3DSMax/files/GUID-BEF2CC1E-40BE-45DD-A8E9-228EE4A1EE98-htm.html
No problem. Hope it helps. With it you will be able to replicate what Tor is doing in that vid. If you enable the spline as geo in the viewport and just draw out with the script active you will get the exact same result.
