Realtime rendering and software rendering?

[pegot]

It is very interesting to have a automatic setting with overlayed kernels, but till then I still find making these visuals as art like the way painters made theirs in the old day

Rappet, thanks for sharing your technique! I hadn't thought to composite different rendering kernels together. But I have done that with differently tonemaped .exr renders when merging from 32 to 16bit in Photoshop. In some ways it is like contrast blending differently exposed images to bring out the most desired parts of you image. I do a lot of HDR panoramic photography and often manually contrast blend the different exposures through this method made popular by Jook Leung (HDR for Dummies):

I sometimes spend hours creating different tonemaped versions of my images to blend in using the above method, and playing with ink modes and masking as well. So I agree that in some ways it is very much like a modern form of painting.

Really sorry for abandoning this thread, only just noticed it had more replies! Appologies.

Hey Jeroen (rappet),
...

That's an interesting technique for interiors... could you maybe send me some example images of the layers and result, if this is interesting for my own workflow I'll program a little tool to auto-overlay the AO. And yes I am already using portals. I'm actually programming an automatic window frame generator for Phantom Architecture that has automatic portals created.

Hi Guus (phantom),

First I do some color corrections seperately on DL, PT and AO rendering... The renders look too dark, but in fact are not, coz' all the information is within the rendered png... I just bring them to the level I want with image correction.
Then in postproduction I mix the enhanced DL with the PT on top with transparancy 50% or different to taste.
And finally I use the AO as overlay for the wanted extra effect, mostly set around 20% transparancy.

There are so many factors that have influence; material settings to start with, and then with your own settings of light and sun, kernel settings, exposure, and other Octane settings, and then the color correction settings in postproduction. If it would be that simple, then OctaneRender should have some standards for interior and exterior settings.. hit one button and boom! But that is not the case... maybe other experienced OR users can get magnificent interiro renders with certain settings, but for me it is still a journey to get the result I am looking for, and it still needs to be improved.
Hopefully these 2cents might send you on a path for a better workflow as well, but you have to follow your own path within your own workflow with lot of trial and errors like I did.

greetz,

Some great info Rappet. Is there any chance you can share these scene files with the different settings so I can see your setup? I'm not sure if your able to do this. Even without blending you seem to get alot of light into the room without too many openings, would love to see how you have achieved this.

Thanks alot for all the replies, this thread has actually turned into a great discussion.

Cheers,

Thanks Rappet! Means alot.

I'll look forward to it!

Glad to help fellow Octaner(s)... I get a lot of help from this community all the time
This zip contains ocs with interior obj like the example.
Notice not only the daylight settings and exposure, but also the glass settings.
As I mentioned earlier I do postproductions to get the actual result.

@Mike, for animations I render al frames and then I use Adobe Premiere by inserting all the frames.
The needed postproduction can be done in a batch (for all the frames) before you handle them in your animation software.. or you might be able to do the post in the animation software?
All depends on your workflow ofcourse.

cheers,

Thanks alot rappet, really helps to see your scene. I didn't have much luck when changing the kernal to diffuse or pathtracing, very dark shadows.

I wonder if instead of rendering out with different kernals, the passes would suffice? It's definitely a no go rendering out different settings for animation. Have you tried using the passes to comp your shots instead of rendering out seperate kernals?

Thanks again for the file, helps alot!
