Giving up on octane

[AndyM1969]

I think perhaps I am trying to run before I can walk, Lightwave came so easily to me, this on the other hand is just giving me headaches.

One bad thing about the engine is that there is not much information outside so you gotta read and study every trick you find, also volumetrics are new to the engine so you can't just expect it to be super easy to use or even perform the best but once you get the hang of it you will be fine.

Here's properly cooked fog/mist.. Details in the foreground are very much visible. It's a choice in post work how much you want it. In a good photo there's little bit of absolute black and little bit of absolute white.

Is there any chance you could post up the empty scene for me, it's driving me nuts how something that should be so simple is proving so difficult. If I can compare your nodes to mine I hope to be able to understand where it is I'm going wrong.

Also, If you have a screengrab of the transmission you mentioned for the leaves, grass.

I know I'm asking a lot but I really appreciate it.

Well, this is not easy. Taking great pictures, with real camera isn't easy. When you see a commercial in a TV, the more easy it looks, more effort has been put into it. To make something look cool and easy, is the sign of serious skill. For example Slash makes guitar playing look so easy and effortless. There's a trick how he does that, and that takes some serious practice.

Instead of looking what I did, I recommend you get into Octane and into photography. Then you are able to recreate any mood / image you wish.

So, with the scene Juanjo posted, just fiddle with the settings. I have mentioned already all what I did, but in this image I also fiddled with white balance setting to get close to same color tone than in your reference image..

Also most important are the actual objects in the scene. The details and materials on them. Displacement maps etc..

There's topic on the leaf material and the transmission setup here:

The problem is I played with Juanjo's scene file for four hours yesterday and either there is something very wrong or I just can't get it. I removed the medium and the scene is perfectly lit, I add the medium back in and it just goes black, I change the medium values and nothing changes. Personally I think something is wrong.

In the scattering medium node I have

density at 0,05
Volume step lenght at 1,0
Phase at 0,8

Environment Texture nore I have LDR image, power set to 5.0, medium radius at 10m.

Scene light temperature is at 4000 and power at 5000.

Imager node I have set to Linear, exposure at 0,18 and gamma at 1,05

Kernel is PMC parallel samples set at max, ray epsilon to 1mm, caustic blur at 10%.

In Photoshop I adjusted litlebit of levels of the image, nothing special.

-------

If you look your reference image, the mist is not that dense. It's actually quite subtle. The light straight from behind just luminates it that way. The initial values in the Juanjo setup were something like what you see in London, in late september, early in the morning, in the docs, when you need a chainsaw to cut trough the fog. You don't see any details in the London streets during those early hours.

That's more than helpful, thank you.

it's not that I don't understand light or photography, I have an advanced diploma in photography from college, I have a feeling it's something to do with me using a 1060 card.

Remember to check that your LW color space (from LW Layout properties) is set to "linear".
