PostProcessing RenderTextureDesc width

Hi all,

I am animating cameras in and out that use the PostProcessing stack. However I am receiving an error when the camera gets too small:

Code (CSharp):

1. ArgumentException: RenderTextureDesc width must be greater than zero.
2. Parameter name: desc.width
3. UnityEngine.RenderTexture.ValidateRenderTextureDesc (RenderTextureDescriptor desc) (at C:/buildslave/unity/build/Runtime/Export/Texture.cs:150)
4. UnityEngine.RenderTexture.GetTemporary (RenderTextureDescriptor desc) (at C:/buildslave/unity/build/Runtime/Export/Texture.cs:130)
5. UnityEngine.RenderTexture.GetTemporary (Int32 width, Int32 height, Int32 depthBuffer, RenderTextureFormat format, RenderTextureReadWrite readWrite, Int32 antiAliasing, RenderTextureMemoryless memorylessMode, VRTextureUsage vrUsage, Boolean useDynamicScale) (at C:/buildslave/unity/build/artifacts/generated/common/runtime/TextureBindings.gen.cs:1180)
6. UnityEngine.RenderTexture.GetTemporary (Int32 width, Int32 height, Int32 depthBuffer, RenderTextureFormat format, RenderTextureReadWrite readWrite) (at C:/buildslave/unity/build/artifacts/generated/common/runtime/TextureBindings.gen.cs:1134)
7. UnityEngine.PostProcessing.RenderTextureFactory.Get (Int32 width, Int32 height, Int32 depthBuffer, RenderTextureFormat format, RenderTextureReadWrite rw, FilterMode filterMode, TextureWrapMode wrapMode, System.String name) (at Assets/PostProcessing/Runtime/Utils/RenderTextureFactory.cs:30)
8. UnityEngine.PostProcessing.BloomComponent.Prepare (UnityEngine.RenderTexture source, UnityEngine.Material uberMaterial, UnityEngine.Texture autoExposure) (at Assets/PostProcessing/Runtime/Components/BloomComponent.cs:86)
9. UnityEngine.PostProcessing.PostProcessingBehaviour.OnRenderImage (UnityEngine.RenderTexture source, UnityEngine.RenderTexture destination) (at Assets/PostProcessing/Runtime/PostProcessingBehaviour.cs:239)

I have tried to set a minimum size for the camera (5 pixels), however the error is still thrown. I'm wondering if anyone might have a solution to this?

Basically I don't want to turn off PostProcessing as that will be jarring as the camera shows/hides, so I'm wondering if there's a way to avoid it calling for a RenderTexture if it's too small. Or even the minimum size the screen can be? I've tried to dig through the code to find out why it's happening, but from what I can find it only ever goes to a quarter of the screen resolution, so making it 5 pixels should be plenty.

Any help is greatly appreciated!

 

I'm actually still struggling with this, in case anyone has any ideas?

 

Same here. Maybe there's a way to turn off post processing for the scene view camera?

 

Any info on this? I'm getting the same issue on 2018.2.7f1

 

I was just having this issue as well. I went down the post processing stack and noticed the error resolved when I decreased the size of the "Radius" slider in the Bloom settings. Hope this helps.

 

[QUOTE = "paradoxedone_unity, post: 4324888, member: 2780590"] У меня тоже была эта проблема. Я спустился вниз по стеку постобработки и заметил, что ошибка устранена, когда я уменьшил размер ползунка «Радиус» в настройках Bloom. Надеюсь, это поможет. [/ QUOTE]

Thanks that worked!
