3d volume textures for games?

Is it possible to generate 3d noise volumes for games?

What I mean is, is it possible for me to modify one of the noise nodes such as to create "slices" of noise that are coherent in the 3rd dimension?

for background, 3d volume textures are an array of 2d textures packed into a single file using the DDS format. 3d textures can be used for a variety of effects, one of which is applying 3d noise to a fog volume to create patchy fog.

I am using FilterForge 4.0.

Thanks.

3d perlin noise can be generated with get_perlin_noise(x,y,z,scale) in a LUA script.

I tried feeding in a value input to the Z axis of the perlin noise, but it seems to stop working. I can output noise slices from 0 to 3, but then numbers higher than 3 output the same result...

I found this thread, seems like the Z parameter doesn't quite do what I was looking for.

i was able to get something to work, but i had to muck around with my input value to get something that sorta looked ok.

i started with the example noise from the documentation.

ideally i would like to be able to make the noise seamless in the Z direction as well, so my and first last slices lined with each other, but it doesn't sound like the Z axis uses the same scale parameter that X and Y use to determine repeat size...

FF doesn't seem like the best tool for it frankly. I would make something similar using AfterEffects. Use the Fractal noise effect, and keyframe the evolve parameter. Under Evolution Options there's a cycle evolution option, that lets you basically loop the fractal noise (you were saying you wanted Z to be seamless as well).

To create seamless textures, you can offset the texture and erase the corners via masking.

You'll probably have to convert the set of images exported from AE, later to DDS format.

Think this does you best.

Also, Houdini has all kinds of periodic 3d noises. Don't know if it supports DDS.

Thanks for the help, Skybase, I made some progress in After Effects, but ran into issues trying to use a Mask on a Noise Layer that has been offset. I abandoned AE, tiling on the X and Y is more important than tiling on the Z, so i'm gonna stick with Filter Forge, maybe add a feature request to make the noise tile-able on the Z axis.

Hey Skybase, I ran into two issues

1. After creating a sequence of 32 frames for the noise to evolve over, I made a copy of the layer.
2. I Offset the Transform of the Noise to 0,0.
3. I applied a Mask to the Layer
3a. This is where the first issue occurs. As soon as I apply the Mask, the Noise changes. I am not sure what changed about the noise, but it is no longer the same the initial Noise. If I change the Mask from Add (the default mode) to None, the Noise returns to the initial state. Of course, when the Mask is set to None, then I don't have a Mask anymore.
4. The second issue I encountered was the Noise Offset to 0,0 would flickered wildly over the 32 frames. The other 3 copies of the noise offset to the other corners did not flicker.
