Specular and normal textures for Dyson-sphere INSIDES?

Post #1by john71 » 17.08.2017, 11:16

Is it possible to create a specular and normal map for the INSIDE surface of a Dyson-sphere?

I want to see the specular atmospheric effects of a central star's light on the INSIDE of a Dyson-sphere.

Can it be done?

OK, I succeeded partly, following this old post:

https://celestiaproject.net/forum/viewtopic.php?f=15&t=16534&p=127244&hilit=cmod+specular#p127244

The inner surface of a cmod sphere is reflecting the light of a star inside of it.

Now let's see if it is possible to use a normal map...

Cmod "normalmap" function does not appear to work on the inner side of the model. Hmmm.

Well, here are the results:

By the way, does anyone have a smoother cmod sphere (around 50MB)?
