Max and Maya Indie are CAD $400 per year for anyone earning less than $100,000 per year from creative work. The full versions, and at that sub cost still less expensive than the upgrade from LW 2020.
To be fair, the new team has not published their LightWave pricing yet for when LW 2023's release.
In any case LightWave pricing for indie freelancers, hobbyists, students, and 3d enthusiasts has got to be (much) more affordable than that 500 pounds. Without the "share" GBP 250 would be more in line with market positioning and feature comparison.
The harsh reality is that all major DCCs: Houdini, Blender, Max, and Maya are less expensive than 250GBP per year for 3D indies and hobbyists, and all DCCs are far ahead in regard to development status and feature set(s). Even Cinema4D is less expensive than GBP 500 per year now.
The new LW team must attract new users somehow. On pricing and feature set alone it is an uphill battle in my opinion. But they say they have a 5 year plan in place to turn LightWave competitive again, so it will be interesting to see how LightWave's new chapter unfolds in the upcoming years.
