Quote from: undefinedIf object motion blur existed in Terragen, how much would that have changed things?
It might have done, the original plan was to import the truck geo and just have it shadow the terrain with primary visibilty off, but the motion blur meant pushing that back to Maya.
In the end it was better to have those elements separated from the TG renders - I had shadows from the volumetrics and it made combining separate shadow passes from the truck, volumetrics, and plants much more flexible.
The TG renders were by far the longest renders (about 1.5 hours per frame on Pixel Plow) and frequently the Maya elements changed so it was better not to have the shadows burnt in.
Quote from: undefinedAnd what would you need material and/or rendering-wise to consider rendering the truck and environment entirely in Terragen?
This was started before path tracing was introduced in TG - it would be interesting to see how a truck render in TG could stand up against Maya/Arnold, motion blur aside.
The truck textures use a lot of UDIMs and there's no support for that in TG? (haven't looked to be honest) and there's a car paint shader on the metal body of the truck (procedural flakes).
I approached it like a vfx studio pipeline setup, and those elements would be separated for flexibility in versioning up animation.
Having said that though, on a personal level with my home setup combining everything in Terragen would have saved me over a months rendering time
