    Bizarre error here - trying to do an "ATF Full Reset" in the Materials (iRay) and received this -

    Is it me or is this looking for a file on your computer Marshian???

    Ah! This came up in testing, thought it was fixed. I'll look into it...

    Follow up- I was able to reproduce the error. This map was a remainder from refining the surface during product development. It actually loads into the Backscattering Glossiness channel which is deactivated and not needed for the preset to work.

    Sorry about this. These products go through a lot of testing and I test my own on a clean system. I'm not sure how this made it through undetected. In the meantime just click ignore, forget, or skip (cant remember these options). It will still work just fine.

    I'll research how many presets are affected and inquire about an update. Thanks for bringing this up!

    Marshian, Thanks ever so much for that breakdown.Some good tips in there..

    I'm busy re-visiting my old scenes to see what can be done with them and your fog prop.. Still experimenting, but this is a really nice tool to have...

    Cheers! Harold

    Harold, 

    Was that rendered in Iray or 3Delight? It looks good :D

  • MarshianMarshian Posts: 1,462

    Oh wow- I love seeing this! That's what I've been doing too- updating old scenes with the fog prop. Actually a few of the promos were created that way. Thanks Harold. It really looks like you're grabbing hold of this.

    I can tell by the variations in the fog that this is the 3DL version. The Iray materials look more like a thick soupy swampy-kinda fog.

    I kinda thought so. I hoped so too since I'm still using 4.7 and 3DL. I bought it but haven't had a chance to play with it yet.

  • MarshianMarshian Posts: 1,462

    WillowRaven- I feel you would very happy with it. Renders in 3DL can still look awesome! Harolds looks great- See below for another example. Like his- the higher point of view seems to work very well...One reason I called it Above The Fog.

    You'll notice the spotlight here has some real character to it- variations in brightness and color. I used a co-product that SickleYield and I worked on: Easy Caustics. Thought I'd mention this as it's part of the charm of this render but it certainly would still look great without it. Actually- my eye is drawn to the cart most of all- I really love how it disappears near the floor.

    Thanks! That's, as Marshian has said, a 3DL render - I don;t use iray as it really doesn't work well at all  on my system..

    I'll point out that if you are really determined, you can do multiple renders in 3DL and Iray and layer the effects together. Off the top of my head: Render Iray with fog Render Iray without fog Render 3DL with everything set to flat black but nice fog. Use the 3DL render as a mask to combine Iray with fog layer and Iray without fog layer

  • Can anyone tell me if Above the Fog using Iray increases render times dramatically?  I rendered an image last night without ATF in about 4 hours and got a very nice clear image.  Decided this morning that some ground fog would be a nice addition so added ATF.  I also included more lighting.  After about 7 hours or so I couldn't get past a grainy image and only around 0.45% converged.  It would probably be a really nice image if not so grainy. :)

    I've found that bounce light is the main culprit for grain. I would expect a longer render with above the fog in general but If your scene has walls and a ceiling....expect longer renders. I've finished some in four, others took seven or ten.

    Just to let you know - it's still occuring, thus far I've only had it happen on the Full Reset so far. I told it to stop asking but it seems that it doesn't completely reset without it.

  • MarshianMarshian Posts: 1,462

    Hi kathrynloch. I will hopefully have some answers about this on Monday. To keep your projects moving until then my solution would be to load a new Iray prop and copy/paste the materials to the surface of the first one in your scene. This will reset the surface of the Above The Fog Iray prop for sure.

    I'm using Stonemason's Enchanted Forest so it could be considered walls and even a celing. :)  I have an hdr and a distant light in the scene which gives it plenty of light.  I don't know if this is going to work but I've resized the prop to cover less ground area.  I'm going to set the render overnight for 8 hours and see what happens.  If it works great, if not I guees the image won't include the fog. :)

  • WillowRavenWillowRaven Posts: 3,787

    Just an idea, which I may not even be understanding the problem ... But if I am understanding, it's the 'walls' of the environment causing and issue. Right? So why not do two renders. One of the environment by itself without the fog then one with the environment 'walls' hidden or removed and the fog in place with the inner elements and use the jpeg of the first render as the 'environment backdrop' and see if that works.

    Or I could just be really confused, lol.

    Lots of leaves— whether they have an opacity/transparency mask or not could slow the render down too. Think about the light having to bounce around all those surfaces. I nice feature of the Iray fog is that it won't show the edges of the geometry (the square shape of the leaves). The 3DL version can show these edges unless the fog is very light. This is one of the main advantages of the Iray version over the 3DL.

    The product is being fixed and updated at this moment. Keep an eye on your DIM as it will tell you when the update for the set is live! It will happen either later today or tomorrow-ish prolly!

    Thanks for your patience!

  • MarshianMarshian Posts: 1,462

    The update is now available in DIM!

  • I am trying to put together a large landscape scene using 3Delight and want some foggy mist to lay along the ground.  I'm not having much luck getting it right so I have a couple of questions:

    1.  Is it better to use multiple instances of ATF; rather than just 1 and scaling it?

    2.  What is the trick to getting the fog to look white?  I've tried changing the colour on the prop from grey to white or a very light pastel colour and I've tried pointing a light at the prop with different colours but I can't seem to get a nice soft white.

    I'm using the AOA lights.

    Any suggestions greatly appreciated.

    Better to use 1 prop and scale it for a large open scene where the fog is just on the ground. When scaling a significant amount the base of the prop can shift. If you change your view point from the camera to left, right, front, or back you'll be able to make sure the fog prop is still sitting right on top of the ground vs floating above or dipping below.

    Color is achieved through the color channel in surfaces tab and the type/amount of light hitting the prop. If you are unsure that you've adjusting the correct color channel (the diffuse color will not work) you can cycle through the color presets and see which one changes. First I would try what you did above (adjust the color channel to white) so since that is not working my guess is it's the lighting.

    The area you pointed the light at- was it a spotlight and was the area being hit with light the white color you're looking for?

    Glad to see you're using AOA lights, this will give you a faster render if you've flagged the fog surface to not be hit. However this will create a darker fog. Lets do a test and see if we are on the right track- Create a distant light set to specular and leave shadows turned off, you dont even have to move it from its default position. Now try a render. Are you using the Aux Viewport? This is so helpful when troubleshooting.

    Is the fog white? If so your answer is with lighting and you can adjust the intensity of the distant specular light to fit the look you are going after. If this didn't work or not enough you may need to adjust the color setting too.

    If these ideas didn't help I may need to see some screen captures and/or a render.

    I apolgise for the slow response.  I had a couple of work projects on the go with deadlines.

    Your suggestions were very helpful and gave me direction.  It is the lighting that makes the difference and I also had to lower the density considerably. It was a bit of a balancing act where I had to be careful with the lighting as it also included the new wolf by AM.  I finally finished the image and though not exactly what I wanted it helped give the effect of depth to the landscape.   If interested I have posted the image at http://www.daz3d.com/gallery/#images/95070/

  • MarshianMarshian Posts: 1,462

    Well done, thanks for sending a link! I think a slight depth of field would help soften the background. 

    It really looks great. The lighting is very tasty.

    Very high on my wishlist

    Finally had a chance to play with this product and a LOVING it.

    Not sure how the mods feels about posting duplicate comments to different threads about the same product, so I'll send ya'll to the thread I started before I learned about this thread.

    I just thought I would post what I did with the Above the Fog.  I used it for the snow on the ground in my entry for the December New User Contest.  The results are in so I finally have this uploaded to my gallery.  It won 2nd place.  Thanks for a great product.  It took a bit to get the look I wanted, but I think it was well worth it.

    edit: forgot to say it was rendered in Iray.

    thanks for posting Knittingmommy. I never thought my product would be taken in this direction. So surprising and great to see experimentation resulting in a dramatic image.

  • I like thinking out of the box.  smiley  It is a great product to work with and once I figured out how to get it to do what I wanted in Iray, it was a huge plus.  It was nice ending the year with such a great render,  Not only did it win 2nd place, it is, to date, my most liked render in my gallery.  I couldn't ask for more than that.
