Basically, I’m using this “hack” : RenderTarget autoClear
to never clear my renderTarget so I can accumulate of top of it.
This renderTarget can be cleared with an input action the user.
To clear the renderTarget manually, I’m clearing the onClearObservable, render the renderTarget, then put back the empty function onClearObservable.
Recently, I added a postprocess on this renderTarget. It’s working well, however I cannot clear anymore, the postprocess seems not to be cleared.
Is it a bug ? I haven’t found a workaround.
