I predominantly use 3ds max for modelling and some basic camera animation. On occasion a bit of particle flow... I've worked in ArchViz and now marketing for years and still only use a tiny part of 3ds max. I think there is room for a smaller product which would be essentially 3ds max under the hood but stripped back using only modelling, material/lighting and basic animation tools.
-Fully inteopable with 3ds max.
-Offered on a monthly sub rental but at a much cheaper cost than full 3ds max.
-Scanline rederer only and the ability to install 3rd party renderers and as a paid module, Arnold.
-No Civil
-No Populate
-Remove legacy modules such as Radiosity (yep, it's still there)
-Allow user to choose the modifiers they need at config statup
-No library content included
-Maybe drop MCG
-Keep Maxscript
-Reduced Viewport functionality. Remove XView and Stylised.
-Trim this fat lad down some!
I think this could be a great opportunity to redesign the massively cumbersome and bloated UI of 3ds max. Dump all the legacy stuff and start fresh. Essentially a UI exercise. I'd love to know what you think.
