Hello - In case anyone is still having issues - I had issues with placing a video on a C4D material and on the background with Octane as well and could not get it to work.



Rendering out a JPEG image sequence instead of a .mp4 and placing it on a C4D material with "Alpha Channel" selected under the octane settings DID WORK


---
using:

Cinema 4D R20
Octane 4.02.1

i followed the solutions but it doesn't work ...

tried all solutions. still doesn't work

I'd same problem and solved it.

1) Render Settings - alpha channel
2) In Octane Settings - Kernel tab - Alpha Channel (Keep environment for HDR visible)
3) For background object Cinema 4d apply octane material - diffuse. (not c4d material, it doesn't work). In diffuse add your texture
4) For shadow catching apply diffuse material. In Diffuse material check in Common - Matte.

Hi,
I found a working solution to those of you who want to work with video clips!
Simply create a jpeg sequence of your video footage and use that in c4d material.
(You will only be able to open one image at a time but when you hit "calculate" in the "animation" that will load the sequence.)
Then reload the octane viewer and that's it.
(For this solution you need to tick the alpha channel in the kernels and some stuff in addition that were mentioned above.)

So here is a new riddle I did all thigs - pathtracing,enable alpha, disable environment, I have been using octane mat and c4d material and pbr material, and video in texture and still image in texture, and camera imager whatever that means but my background is not visible unfortunetly. Can someone knows what is going on in my relationship with octane?

Hi dekar07,
please thy these steps:
- enable the alpha Channel option in Kernel setting,
- create a c4d Background object,
- apply an Octane Diffuse material to it,
- create an Imagetexture node in Diffuse pin with the desired image file inside:

Hi Beppe.

I have been going nuts over this for a long time.
I have followed your steps and it was still not working. Couldn´t believe it, so:

As I always render to viewport, I tried to render to Live Viewer window and indeed it DOES render the background there, but NOT in the viewport.

Also the background object with the octane diffuse material is not showed in the active camera viewport when octane render is paused or not started.
So I need to have
1- backround object with a standard c4D material YES visible on editor/NOT visible to render
and
2-backround object with a octane diffuse material NOT visible on editor/ YES visible to render

Any help will be very wellcomed.

Hi,
instead of the c4d Background object, you can use an Octane Environment Object, in Visible Environment mode, with Backplate active.
Then change the Projection to OSL Projection, and choose the cameraEnvPrjOSL preset:

Hi Beppe, thanks, that works in the viewport render.

How should I adjust the OSL projection (size) to match the camera, it's a vfx background plate I need as background reference. The texture is tiled now and not accounting for the camera aspect ratio.
