hello everybody,

I try to do a movie on octane and I have different problems on it .

First one is about displacement :

I have one shot about moon . when I put the displacement on the moon I have a bug if I put my camera on the ground of the moon (cf screen shot 01).
I think it's because I can't choose upper than 8192*8192 in level of detail . Is it possible to override this attribut ? Do you have other solutions ? Second one is when I want render my sequence :

I don't know why but cinema4d don't give me same image between live viewer and batch render .
Subdivision with object tag don't work
Emission material don't work
Not all post process effects don't work
and my grading is a little bit different .

(cf screen shot 02) Last one :

Can I transfer all my work in cinema4d to standalone easly and keep animation with alembic ? script ?

thanks much
Romain

Hi,
i start from last. i have explained this differences several times. Please read last one: http://render.otoy.com/forum/viewtopic.php?f=30&t=40997
there is two main method in rendering. First is as a collecting all to a single mesh, second is exactly same in LV.
You should use second. Emission needs to put a objecttag. If you collect all emissive geometry to a single mesh, this causes to loose illumination. That's the reason of using objecttag.

Also keep in your mind, LV is not for final output. It's a previewing window. But you can get exactly same results mostly (except mblur and hairs).

Color different: What's you render buffer type? float or 8bit? Do you have multipasses? This affects colors. But Octane gives correct output for AE, etc... You should check saved images if you have multipasses.

Displacement: It works well if you have images big enough. Also use 32bit images for displacement. And check scaling and ray epsilon.

hi ,

thanks a lot . now I have almost the good result on the sattelite .

How can I keep my subdivisions on final output ?
I tried displacement with a procedural noise and the problem is same .... can I override level of detail with scripting ?

It's a limit of renderer. max 8192. But i suspect why looks so bad. Maybe something is wrong or very big surface for this resolution. Bu i said that you should use 32bit image for better displacement. You may think to divide your object and apply a few displacement
