That means, switching between different "surface-settings" is not possible without loosing the actual material setup.

How to reproduce:
Make a new matrial. IE a diffuse.
Add a texture node to the nodesetup and connect it to Diffusechanel from the diffuse Mat (or anywhere).
Now go to the Surface-windows and change Diffuse Mat in the dropdown to specular.
Now you see, that the texture node will be automaticly deleted.
Switching back to diffuse doesnt give me the textur back.

The good way would be to be able to switch between different surface settings.

You will have the same in Cycles nodes. It is just matter of socket name: if you switch to node which does not have the socket named the same as to which is your another node connected - this another node will be deleted. This is a workaround of ambiguity: we don't know to which socket to connect the previously connected node, as the socket having another name may have absolutely differrent semantics...
This is not Octane's behavior - this algorythm is coded inside Blender node system. I could improve it - but this work would be not bound to Octane plugin, and Otoy can not spend too much resources to improve Blender itself... So, it should be changed in the Blender trunk itself...

I just have not paid too much attention to this, so it may work, but so far I do not guarantee that it will work.

How did you get animated textures to work? What format did you use? Image sequences don't work for me and movie files get me a "File Format Error" and OctaneServer terminates (with Linux).

Hey all, Does anyone know if the new plugin currently does or at some point will recognize particles or particle hair created in blender?

Sorry, I'm not a cool 3D-artist, so it's what even the programmer can do in a minute. I think artists here are able to show something better...
But you should understand, that Octane engine so far does not support the native hairs, as Cycles does. So, so far you can do it only using Blender particles.

hi everyone, i don't know if i've get this wrong. I don't purchase the blender plugin yet, but in this topic i was able to download the blender patched version and the server. Anyway i've installed both and run the server, but when i run the blender for octane version it seems to run the normal version, indeed i don't see octane in the engines list. I'm i do something wrong? Are those downloadable file supposed to try the plugin?

Hi Evo,

You will need to enable the module.
Take a look at the bottom of here: http://render.otoy.com/manuals/Blender/?page_id=22

Thanks
Chris.

You can't try this version. It is not the demo, so you'll need the license key to use it.

I didn´t know that ... interesting!
You should not spend too much time in improving Blender generaly.
Is it possible to add a save-option for node setups ... something working together with der DB?

Very great - thank you! Seems to work, except the actualization of the live-preview .

I got it working using PNG-Sequences (im on Windows 7).
Just use the Octane Texture Node, load the 1st seq-image and config it to sequence.
Dont forget to set the max frames
AVI made the same problems.

Almost missed this little gem in the last cycle thread just before we warped again!

Regarding the number of samples, I opened Blender, changed them to what I want for a default and told it to save the startup file. It loads my default values each time Blender starts.

Thanks! An easy fix. It works.

Hi!
Could someone explain how to set a diffuse material to emit light in its textures colors?

iE, take an image of a rainbow. Use it as texture for a diffuse material.
How can i make it emit with its texture and lighten objects with that?
