If I want to create an equarecangular panorama (like the HDRI images we all know and love) … if I use a glare node then it won’t work so well round the poles. Does anyone know a good way round this?
As far as I know, there are no easy ways. Easiest way is probably to convert your equi image to cubemap, apply glare to pole areas there and then merge pole areas back over glared equi image.
Even a simple blur needs modifications for it to work on panoramic footage, I’m not sure there is any widely used soft that does proper panoramic filters.
