Another Cloud Tutorial

 5/3/23

I was looking into other ways to make the clouds since the other method uses lots of particles and that could affect the performance of the final result if there are lots of them.

https://youtu.be/g8A0Etf-ekY I found this video that creates a cloud-like material. These are the steps: 

Create material with subsurface shading and flat tessellations. 

Give a constant (0.95) to the base colour. (1 left click to add this node?)

Add a noise node and lower the scale in the node settings (0.001)

M left click for multiply node, multiply by 100. Then add a clamp node (-200, 200) which reduces sharp points. 

Multiply this by vertex normal (needed for tessellations) and connect this result to the world displacement. 

Add another constant node (2-10) to connect to the tessellation multiplier.

Another constant for the opacity (0.5).

and another constant node for both the emissive colour and subsurface colour (0.005).

However, after watching the video I noticed in the comments that the tessellation feature is discontiued in unreal engine 5. 

The video created mentions using World position offset instead.
