Post effect scripts error when toggling camera component enabled state #5793

Closed lucaheft closed 10 months ago

lucaheft commented 10 months ago

Description

Post effects throw errors, when camera component is disabled and enabled again. I only tested this with posteffect-brightnesscontrast.js but this propably applies to all post effects.

Error:

ASSERT FAILED:

Framebuffer creation failed with error code FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT, render target: Camera-posteffect-0

[object Object]

Shader [Shader Id 0 BrightnessContrastShader] requires texture sampler [uColorBuffer] which has not been set, while rendering [Pass:Postprocess | BrightnessContrastEffect | Pass:RenderPass-drawQuadWithShaderFramebuffer | drawQuadWithShader | QuadRender]

Steps to Reproduce

  1. Go to: https://playcanvas.com/project/1159639/overview/bug-post-effect-enabledisable
  2. Press play
  3. Disable camera component in editor
  4. Enable camera component in editor
  5. Post effect errors and gets stuck at current value

most likely a duplicate of https://github.com/playcanvas/engine/issues/4787 - see the workaround there. I'll close this for now, but please reopen if this is not the same issue.
