When you render the offscreen buffer, Panda encounters the ComputeNode in the scene graph too, and in this case the shader on the ComputeNode is being overridden by your initial state, resulting in the ComputeNode being dispatched without a valid compute shader: temp_node = NodePath("temp")
temp_node.set_shader(shader, 1)
temp_node.set_shader_input("SomeInput", 0)
camera.node().set_initial_state(temp_node.get_state())You should hide your ComputeNode from this camera using draw masks. |

Yes, that was it.
I can't, I don't think. In my real code I'm instantiating multiple cameras as different viewpoints, and disabling the main camera. I specifically need the compute shader to go off after that camera renders to the buffer, because I need to read from it. Unless something else causes it to go off? (Although given that extracting the data from a non-fbo takes so much time due to stalls, besides being delayed, I may have to go back to pixel shaders anyways). Beyond that, I can re-apply the compute shader by giving a higher override, but I haven't been able to get draw masks to correctly control the compute shader - the following outputs a red screen, but should be yellow, I think (and is if from typing import Tuple

You just want to set the camera mask to eg. |
This wouldn't help in my real code, because I potentially only have one camera (the extra one here is only being used for debug output). compute_chain.hide()
compute_chain.show(DrawMask.all_on())unhide for everything? |

Description
If a compute shader is given a buffer that is the output of a framebuffer, for example one handed to
add_render_texture(), then a gl error message is generated:... despite this message, the compute shader actually runs (and appears to run successfully).
