Shader input scatteringOptions is not present

Hi,

• Installed panda 1.10 from a nightly build on http://www.panda3d.org/download.php?platform=windows&version=devel&sdk
• Downloaded the RenderPipeline from the master branch
• Created a program based on the sample at https://github.com/tobspr/RenderPipeline/blob/master/Samples/01-Simple/main.py

I ran the sample and received the following issues:

  File "F:\dev\Work\tobspr\main.py", line 43, in __init__
    self.skybox = self.renderPipeline.getDefaultSkybox()
AttributeError: RenderingPipeline instance has no attribute 'getDefaultSkybox'

So I commented out the skybox code.

Traceback (most recent call last):
  File "F:\dev\Work\tobspr\main.py", line 61, in <module>
    app = App()
  File "F:\dev\Work\tobspr\main.py", line 49, in __init__
    self.controller.setInitialPositionHpr(
AttributeError: MovementController instance has no attribute 'setInitialPositionHpr'

Commented out the controller code

  File "F:\dev\Work\tobspr\main.py", line 61, in <module>
    app = App()
  File "F:\dev\Work\tobspr\main.py", line 58, in __init__
    self.renderPipeline.onSceneInitialized()
AttributeError: RenderingPipeline instance has no attribute 'onSceneInitialized'

Commented out the onSceneInitialized...

And - I couldn't get past this issue. I initially tried setting up the render pipeline in my existing project, and got the same issue, but I thought it might be because I'm using some custom shaders. So I setup a clean project, and get the same problem. Any ideas? Do I need to throw render some default shader inputs?

Hi, this is a strange issue, usually you should not have to comment out anything, the errors you get are because you commented out those lines.
I will investigate into this this afternoon, I believe the sample might be outdated.

Cheers,

Hm, can you make sure you checked out the master and not the refactoring_beta branch? In the master branch the functions are named different than in the refactoring branch, so thats what could cause your issue

Gah - sometimes I'm such an idiot. I'm not sure what happened there, but yeah - I didn't grab the correct version. After replacing the lightingModels.include, I'm now running the sample.

I did have to disable GI - as it kept displaying the 'computing gi - be patient', and wouldn't continue. But I'm mainly looking to use the awesome lighting / shadowing - so thats not an issue for me.

Thanks for the help anyway!
