Day 4 - Module 9

Custom Shader

Ring
Today I started on module 9, I've learned more about the shop network. I had previously tried on this shop network but I didn't really get it as I'll get confused on which node should I use and how to connect those nodes together etc. So today I gone through the tutorial and managed to get a better hang of it. I've tried on two examples today, the first one is ring shader and another one is the grass shader. So for the ring shader, I find it still manageable.

However, I realised that in order to create just a simple shader, we'll also have to use a lot of nodes which looks quite complicated to understand.

This is the end product of my ring! It was quite fun actually.

To create more rings in a grid, I'll have to adjust the S & T frequency.

Then to make it look more random, I'll have to adjust my S & T randomness.

I've also learned a new thing which is we don't actually have to duplicate the current shader that we've done to change another grid to another colour. We can go to the "Ring1" material and "Create all local material parameters"

Grass
Next, I moved on to create the grass shader. This was much more complicated than the previous one.

I test render out but it still look quite flat currently.

Initially, I had problem on how to make the grass to be more 3D and I tried to rewatch the tutorial again but couldn't solve it. Eventually, I found out that at the properties node there, I didn't put the displacement bound to 5 but I left it at 0. That's why the grass looks flat.
This is my final network for grass.

I tried to render it out but it look too spiky.

So I made some adjustments and here's the final one.

I'll proceed on to do module 10.
