The thread starts as a discussion of MatMatic fog; but changes to simple node based fog planes too. http://www.runtimedna.com/mod/forum/messages.php?ShowMessage=316436 Something similar: http://www.runtimedna.com/mod/forum/messages.php?ShowMessage=264139 I have found many useful tips in this forum {Some are waaay over my head; though that doesn't stop me from gathering some insight from them.}; if you like the info here, I suggest setting the "email notification enabled" to yes, that way you will get an email whenever someone creates a new post in the topic forum (This is available for all forums at RDNA).

In this one I used two planes with different texturing, in an attempt to create some depth to the fog.

Maybe you could tell us in your own words how you did it. (Kenny is putting Whazizname on the chopping block.) :wink: O:) :lmao: :thumb:[/quote] Heheh... that very thought lead me to do another experiment last night ("great minds think alike"); so not only will I explain it, I'll post an image & a screen capture of the materials room. :) Explaination: Load a "one sided square" (from Poser's primitives...); rotate it to be parallel to the scene ground (visible side up!); then Y trans it to the desired height (ankle, or knee height works well); scale it to fill the desired area; Go to materials room, and attach a Fractal Sum node to the transparency & transparency_edge channels; set both values to 1.0 (falloff can be left as is, or adjusted to your tastes); Adjust X, Y, Z scaling in Fractal Sum node to get the desired fog "pattern" (other settings in the node can be be adjusted as desired); Change diffuse color of square to light bluish color (for normal fog; other colors can be used for "otherworldly" fog, or smoke); In low light scenes, I also change the ambient color to a light bluish tone, then set it's value to about .3. (I suppose that the "alternate diffuse" channel could also be used for this; but I have not tried it yet.) {The thread suggests attaching the Fractal Sum node to the displacement channel to increase the appearence of fog depth; but I think the change is too subtle (perhaps it works better in newer versions of Poser...); so instead, I use multiple squares, each with slightly different FBM settings, and colors.} The images: ----------------------------------- Whazizname Thursday, 30 August 2007, 03:57 PM Re: Fog ----------------------------------- Oops; I always forget what order the attached images will appear in. I think I'll post the "most satisfying" version of this image to the album; because it did turn out kind of nice. :) {Whazizname exits chopping block... :walk:} :grin: (: ----------------------------------- tda42 Thursday, 30 August 2007, 08:31 PM Re: Fog ----------------------------------- [quote user="Whazizname" post="36913"]{Whazizname exits chopping block... :walk:} :grin: (:[/quote] :lmao: This is why I love this place, the people and have been here for over 4 years now.

If you have Bryce 6. Build a lattice model and make it with uneven ground to give it a wave like effect. Export to Poser as a object file. Then use it for the fog instead of the flat square. :thumb: ----------------------------------- Posy Friday, 31 August 2007, 12:47 AM ----------------------------------- But I don't have it. ----------------------------------- Whazizname Friday, 31 August 2007, 05:46 AM Re: Fog ----------------------------------- I think that is a good idea Tda42; I bet it would work with a terrain object too (for those that have Bryce 4, or 5).

I'll let you know. :thumb: ----------------------------------- JanReinar Sunday, 02 September 2007, 04:06 AM Re: Fog ----------------------------------- Thanks for the tips Whazizname!

(I haven't started experiementing yet; but the idea is simmering in my brain...)

Mmmm...I think another alternative would be 2d textures>clouds clouds could give more realistic effects....if done as a trans map for a cloth plane/cube which is coloured as the fogs' base colour. Just giving a thought.....afterall the best fogs/clouds are Bryce. ----------------------------------- Whazizname Sunday, 16 September 2007, 07:56 PM Re: Fog ----------------------------------- [quote user="hanzoushinrei" post="37009"]FRACTAL SUM?

Just giving a thought.....afterall the best fogs/clouds are Bryce.[/quote] Yes, the clouds node will work for this, as will the FBM node; but for me (and the thread's author...) Fractal Sum gives more pleasing results. I also agree the Bryce clouds & fog are great; I'm one of those creatives that likes to see how much can I get out of one application. (Sidenote: I spent months in the late '90s teaching myself to draw/paint realistic clouds in Photoshop 3.0; although I could have simply used Bryce 2.)
