Clipping primitive; two ClippingBoxes at the same time

[DreVinciCode]

Hello,

I tried following these instructions to add a second ClippingBox to a renderer. I had some of issues that came up:

1. The MonoBehaviour script SecondClippingBox does not reference the variable clipBoxSizeID, and the script requires including the namespace Microsoft.MixedReality.Toolkit.Utilities. I commented out the clipBoxSizeID and included the namespace to the script.

2. Modifying the MRTK/Core/StandardAssets/Shaders/MixedRealityStandard.shader in step 5 for #if defined(_CLIPPING_BOX2). I changed the code to include variables clipBoxSide2 and clipBoxInverseTransform2 to match the format of #if defined(_CLIPPING_BOX). I also removed the argument _ClipBoxSize2.xyz from PointVsBox().

Making these changes worked for me :) I included some screenshots.

@Cameron-Micka, any insight?

@keveleigh ah yes, we need to update these docs to reflect some PRs that have gone in over the years. (I think this bugcalls this out too.)

I did recently update the steps in MRTK3, so they should be correct: https://learn.microsoft.com/en-us/windows/mixed-reality/mrtk-unity/mrtk3-graphicstools/features/clipping-primitive#advanced-usage

@DreVinciCode Hi, I also have a problem following the instruction. I looked into your screenshot, but still the second box is not clipping my model.

I wonder what is wrong and here are the codes I changed according to the instruction and your answer.

Step 1:

Step 2:

Step 3:

Step 4:

Step 5:

Finally, here are the clipping boxes in the scene.

I am using MRTK 2 and created a new material with the altered standard shader. I would really appreciate it if someone can have a look at my settings. Thanks in advance.
