Cloud movement question

Hey guys, first post here :)

Sorry if this has already been answered. I did a search and couldn't find any info about my issue. I want to be able to move my clouds (say, to the left of the camera) without moving the camera. I don't mean an animation, I'd just like to be able to move clouds while still having the same landscape view. Is there any way to move the cloud layer? Many thanks!

Hi Aagam, welcome to the forum :)
If you add a transform shader between the cloud shader and its Cloud fractal shader that should do the trick. Although you cant rotate the clouds (maybe through cleaver use of  function nodes ...) you will be able to place and move your cloud structures to any place you want over your planet.
Happy rendering

Thanks cyphyr!

I'm quite new to Terragen 2 and still getting used to how the system works. I'm a little confused about how you add the shaders. Could anyone help or direct me to a place I can get more info? Thanks :)

Connect the cloud density fractal output to the shader input of the Transform shader node, and then connect the output from that into the cloud's Density shader input

If you "right click" in the node window a whole list of nodes pops up, simply choose the transform shader from these (I think its listed under Other Shader) and it will appear where you right clicked, now link it up and your done.

Okay so I've linked everything up properly and open up the shader controls. I assume "translate" stays at 0, and the scaling is turned to whatever you want. Unfortunately, no matter what I turn it too (whether 500, 5000, etc), the clouds don't seem to move. Do I need to toggle the translate shader too :(?

cyphyr

try the other way round. leave scale at 0 and translate to what ever you need.

Still not working unfortunately :(

I left the scaling values at 0 and tried turning transform to 1000, however the clouds stay in the same place.

bigben

You've connected the fractal node to the Shader input of the transform node and not the Input (the input on the right)?

Aagam

Here's an image of the nodes:

I'd upload it here but storage seems to be full.

bigben

Connect the density fractal to the other input of the transform shader.

Aagam

Bla, stupid mistake by me. Thanks ya, works now.
