Title: Inverted Slope Limits
Post by: WAS on February 15, 2021, 04:37:23 PM
Can someone, for my sanities sake explain/demonstrate how one would target a specific slope restriction when you're working with inverted terrain/planet? I can't get the same look as I do on a normal planet and I think I'm just not mathing in my head right. Hopefully it's not just a limitation in TG

By inverted terrain you mean something like the ceiling of a cave?

Basically, or a inverted sphere (Negative radius).

Wanted to export planet maps that more represent the non inverted look

So you render spherically from the 0/0/0, I see. I would say, theoretically, that slopes are the same whether inverted or not. So you found a difference?

Mmmm. Mask is going upside down, and rotating the sphere obviously doesn't help. I don't see a way out, unless you rotate the texture 180ยบ afterwards, or flip it vertically. And when I set scale Y=-1 TG crashed.

With an inverted sphere you are basically consistently trying to sample the surface laterally, similar to how difficult it can be to populate laterally displaced surfaces, and TG has difficulties with that by design.
I'll think about it...
