Simple Blender Cloud Texture Maker

Post #1by MrSpace43 » 30.05.2021, 21:43

So earlier today, I made a cloud texture map generator in Blender, and I am releasing it to the public for anyone to use:
https://www.mediafire.com/file/xmzo96pxoe492ri/Cloud_Texture_Maker.blend/file
(This only works in v2.83.3 or higher)

So when you open the file, you should get something that looks like this:
Pic1.png

What we have to do now is change the render setting to "Viewport Shading" by clicking this icon at the top-right of the window with the sphere:

You should now see this:

If we go down to the node tab and move over, we see this noise setting which will determine the look of the clouds:

-W: This is just the seed for the texture
-Distortion: I recommend setting it between 0.3 and 0.85
-Scale: Set this between 4.5 and 10 for something that looks Earth-like
LEAVE EVERYTHING ELSE UNTOUCHED

When you get something you are satisfied with, select this node and click on the "New Image" icon circled in red:

You should get this menu. Make sure you have the width and height in a 2:1 ratio (example: 4096x2048). You can name the image anything you like. Once done, click "OK":

Make sure that you have the sphere and the image node selected, and then click on "Bake":
Pic7.png

This will take some time depending on your PC or the size of the image texture that you set.

Once the texture is finished being baked, you should see the output on the bottom-left, but we aren't actually gonna touch this here:
Pic8.png

We are instead going to click the "Texture Paint" tab:

You should see this menu:

You will then click on "Image," and then "Save As...":

Find a good place to save the file, and voilà! an alpha cloud map texture ready for any use:

possible to make a verson that works in 2.70 (or other versons below 2.83.3)?
i am asking because not everyone can use the compatible versions with this verson of the cloud gen bc of computer limitations

Yeah sorry but I can't help on that, as I don't want to waste another hour or 2 to make a new preset (not all versions of blender are equal, and I don't use blender much).

Funny though, my setup is actually a lot simpler, as it uses a total of only 6 nodes.

well i stuck in a "maprange" node before the "color ramp" node to keep all the values in the positive

basically i am subtracting two noise sources from each other
