A couple of days ago I created an updated guide of how to install LightWave 5 on AmigaOS 4.1 FE, having all the screen work fine on a full RTG system. It is full of screenshots, guiding the user step by step on what needs to be done.
It includes information found around forum threads and videos, like the ones from mbrantley, including a lot of experimentation.
You can find it at https://intuitionbase.com/articles/runn ... -amigaos-4
Hope it will be useful for everyone who wants to render on their NG Amigas.
