when you plan to implement hair fur and region?
thats ok if still no plan yet, but let us know the Octane3dsmax road map
so I can prepare for my future project

That will probably be available in 2.x. Don't ask me when.

Hi Karba
I can't understand why region render is so difficult to implement

1 - select a region on the screen, a simple rectangle will do the job.
2 - calculate new region dimensions and center.
3 - calculate new Lens = original Lens * original width / region width
4a - calculate x shift = (region x center - original x center) / region width
4b - calculate y shift = (region y center - original y center) / region height
5 - render the region in the right place of the frame buffer
See image below ...

I think a simple script could do the job in 3dsmax : scripters are welcome.
NB : a good think would be to take in account the original x and y shift.

that's all folks


[EDIT] I made a mistake : zero-zero must be down-left because Y shift >0 is Up.

Thanks!
I wonder; When will we be able to use xref without merging the materials? or even the containers?

OK I see now. It works on xref object, except for lights, but xref scene don´t work at all. Xref object is great though!

second edit: It works on single octane materials but not multi-sub materials!

What shows up in the reflective surfaces is the default color or the texture of the ground plane, instead of reflecting the full environment with the shadow catcher showing the texture environment as the ground plane..

is there a work around or am I missing something?

Shadow catcher doesn't work with reflections, only with diffuse component.

so is there a work around? whereby the ground plane using the shadow catacher can be mapped with the texture environment so it can show up in the reflections?

Amazing JOB!!! please tell me about how to calculate the new x and y lens shift when the original render has its own lens shift!!! It's very important!!! for example , original render res is 1080P with X lenshift=0.5 and Y lenshift=0.2!! Please tell me how to do the formula!!!!Thank you so much!!!!

just a bit of geometry ...
here a calc file with formulas assuming zero-zero is the down-left of the image.


For sure, vigneting and post proc will not work well that way.

tested and worked!!! again thank you so much Sir!!! u just turn me on
I will try to make a small video to show everyone this such amazing gift!!!!!
but still,a simple max script can do the whole job!!!!!
