Hi guys, so an OctaneVR subscription is required to test the alpha? No dice with a purchased standalone license?

Right now it's the easiest way to support testing - but in final release it will be free to everyone.

If you have ever used ORC, you already have a free OVR license for a year to go with that. We'll add a 30 day OVR license for up to 100 permanent users (without ORC/OVR) who want to do testing and provide feedback on this forum - starting with you!

I just installed Octane for Unity but so far only limited success. Using Unity 2017.1.0f2. and a native Unity scene (not orbx).

The first install went fine, but I got a nullreference exception a few times per second in the Unity console. Then I uninstalled Octane for Unity (via the Unity menu, not the exe) and installed again. After going to Unity->Octane->Install again, I got this error with the installation failed (no menu items but install available):

IOException: Sharing violation on path C:\Users\USER\AppData\Local\Octane\Unity\2017.1.0f2_0.9.2.801\octane.dll

UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at C:/buildslave/unity/build/Editor/Mono/EditorApplication.cs:109)


Then I closed Unity, uninstalled Octane via windows control panel, installed the exe again, and started Unity. Then I clicked on Unity->Octane->Install again. This time no install error.

But after loading Octane in Unity, I got this error many times again:

NullReferenceException: Object reference not set to an instance of an object
OctaneUnity.ResourceMapper.UpdateInstance (UnityEngine.GameObject obj)
OctaneUnity.Scene.AddObject (UnityEngine.GameObject obj, OctaneUnity.SceneGraphNode parentNode)
OctaneUnity.Scene.UpdateGameObject (UnityEngine.GameObject gameObject)

OctaneUnity.PluginController.Update ()
UnityEditor.EditorApplication.Internal_CallUpdateFunctions () (at C:/buildslave/unity/build/Editor/Mono/EditorApplication.cs:109)


When unloading Octane, Unity crashed. Started Unity again and loaded Octane. Same error returned. Adding a PBR render target did not solve the issue.

Then I tried to get the caustic example to work. I created a new scene and imported the unitypackage. It should be mentioned in the manual that you need to install Octane via the Unity menu first after creating a new scene before you can drag and drop an orbx file into the scene. Aside from that, when I drag and drop the caustics orbx scene into the Hierarchy, nothing happens and no error is shown. When I drag and drop the orbx scene into the Scene window, I get this error:

NullReferenceException: Object reference not set to an instance of an object

UnityEditor.HostView.InvokeOnGUI (Rect onGUIPosition) (at C:/buildslave/unity/build/Editor/Mono/HostView.cs:232)


Now I tried using a fresh scene with just a standard Unity cube. First I did Unity->Octane->Install but was stuck at Downloading Octane, connecting... Internet is fine. Why does it need to re-download Ocatane for the 10th time in half an hour? Surely it should be up to the user if he wants to download the latest version or use the previously downloaded version on disc.

Restarted Unity and tried installing, and auto downloading again. This time downloading works. If forcing the user to download the latest version (which is the latest anyway), perhaps adding a timeout and retry would be helpful.

Anyway, after installing Octane in Unity, I added a cube to the scene, then loaded Octane. This time no error. Yay! Rendering works fine.

Feedback:
-Fix the error I get with my scene. PM me for the source.
-Fix the ability to drag and drop an orbx scene in the Hierarchy and Scene window.
-Display the render result in the Game window instead of a separate render preview window.
-The manual states Unity mappings: Render target, but there is no such thing as render target. What you mean is Hierarchy->PBR Render Target (game object)->Inspector->PBR Render Target Component->Camera->Select camera.
-Don't force to download the same thing over and over.
-Right clicking on the Hierarchy "Create PBR render target" should have the name Octane in it and it doesn't work if Octane is not loaded yet.
-Closing Unity when Octane is loaded, crashes Unity.

Hey Goldorak

I own the Standalone and a Houdini Octane license. I have used ORC to do a simple test, but for some reason I still get the message "Could not find the required license" when I try to activate Octane within Unity. Would it be possible for me to join the testers, or should I just wait until the full release?

Thanks!

Any chance we can get added as well to the testing? We purchased the standalone + 3ds max ONLY because its coming to Unity and we wanted to get a little more familiar with Octane. Lets just say being barred from testing after spending money on this awaiting Unity is frustrating :).
