OctaneRender™ Standalone 1.23

[Lutze]

Animation from Houdini to Octane now works fine with alembic which is fantastic. Only... the camera position is not transfered into octane, instead it will always start the scene with the camera at the default position. This makes it again barely usefull. Anyone some intelligent tips how to fix this?

maybe it's possible with lua script, get camera position from alembic and transfer to octane's camera

[Lutze]

Hmmm, haven´t uesed Octane for several months now and therefor please don´t laugh at me... but what is a lua-script?

Maya 2014 exports materials through a GPU cache. I can try and export teh cahe file to you if you think it might help.
Perhaps the Alembic animation can be hooked into the cache file in some way... you know.. by unicorns and the easter bunny.

Roeland See if these make any sense... or are of use to ya aye.

@Lutze,
Lua is the new scripting capability within Octane. Lua is a computer language. Its use in Octane is like Python is to Blender. You can write your own code and run it to accomplish tasks like automate the movement of the camera or more complex things. It is only a very recent addition. You can find a new forum for Lua scripting in 'Resources and Sharing' where the Otoy guys are providing some examples of how to code using it.
Nice to see you back here.

Are you rendering the imported Scene node directly?

If an alembic file contains camera data you will see, in addition to the purple (geometry) output pin, one or more blue output pins for the camera data. If you have only a geometry output then the exported file probably doesn't contain camera data, and you may have to enable it in Houdini.

If there is camera data, the easiest way to use it is to create a render target node, and make a connection from the geometry output pin of the scene node to the render target geometry input pin, and similar for the camera pins. Then, render the render target node.

Hi Roeland,

this did the trick.Thanks a lot...now I will try to get back into octane.

I'm not really too sure how to describe this problem. All I did was to add a second render target node and connected it to the same pin on the geometry node as the first target node. When I rotate the view on the second target node the focus blur goes in and out as you move the camera. It's like at certain angles the focus doesn't work right? Focal depth doesn't change and always is set to 1.

focus blur goes in and out as you move the camera.

I have experienced this few times.
