Gaea School

 Masking Rivers

So you want to export river masks? Not too hard. Here is an example node-tree:


1. Create your terrain. Add Rivers (obvs!)
2. Portal out for colour outputs. Add a TextureBase which intelligently masks different types of topology, such as slopes.

3. Add a portal to the Rivers node from the Rivers output. You can export this directly for your mask, but if you want an integrated colour map, use two SatMaps one for the ground and one for the river, then use the River node output for the mask on the combine node.

Onwards into Quintilus (or Septimus)

 Harsh week. Back pain. Chronic sleep deprivation. Stresses and strains. We endure!

Diabetes

I'm off the medication, handling my insulin resistance through diet and exercise alone! Yay! Now to stay on the straight and narrow, so that my next HbA1c test continues to show me below the pre-diabetes range.



Halo: Raptor

I chatted with the director about my progress with Gaea. We're looking at using Gaea for my next scene. In the meantime, I will be doing some quick test terrains to see if I can muster the right type and quality.

I also need to finish the city. For this, I need to grab the terrain beneath the city and create a copy of its topology so I can properly map the roads onto it. Currently, much of the city's surface level is sunk below the hills.


Now, let's see if I can break out of my disconbobulation and get some productivity.
