For those of you who are too lazy to make your own clouds, but don’t really want to pay $100 for an advanced cloud system.
Easy-to-use, fast and good-looking advanced perlin clouds.
Since this is our first asset (and we are planning several more), any feedback would be appreciated - we’re already planning on implementing an additional terrain shader for terrain shadows.
Hey leuat,
I’m interested in your cloud Asset.
2 questions:
Your Video does not show cloud shadows on the terrain. Would it be possible to add those? (I have Unity Pro).
The sky seems to be flat. Would it be possible to map it onto a sphere instead?
For the sphere one would need 3d or 4d noise to avoid seams. Is your noise calculation done in the shader?
I don’t ask you to add those things. I just want you to elaborate a bit how your system works and if you think it can be adapted to my needs (by myself).
Sure thing! This asset was meant as a “test case” for my part, and will probably be updated later with a more advanced shader. Changing the cloud from a plane to a sphere would be quite simple, but you will have to change some parts of the shader (like, calculating normals) and make sure you have decent mapping.
I agree that you would like 3/4d noise. Unfortunately, calculating perlin noise real-time in a shader is slow - possible, but slow. I currently use a look-up-texture for calculating the clouds, but I guess this could easily be changed to a 3D texture lookup - but you’d have to generate that texture first, I guess.
In any case, many interesting ideas here - let me know what you think =) I’ll be continuing on my other (real) assets, such as the terrain texture generators.
ok, then i will purchase your asset the next days and have a look into it. i just “fear” that when all clouds around the planet move with same speed in same direction it looks too much like a static cloud layer from above. from surface one only sees a fraction of it and it should not matter that much. interesting learning resource anyway for me.
