Float pixels GPU to CPU

Hi,

I made some shaders that fills datas that I want to re-use for a partucule system that will run on the CPU.
I’m using ofPixels_<'float> with OF_PIXEL_ARGB, I use something like this

fbo.readToPixels(myPixelsObject);

I get some random values that has nothing to do with the texture that was wrote on the GPU.

what Am I missing ?

thanks :slight_smile:
