- Otherwise bloom intensity will not properly match the bright regions of the final image. - Can be disabled using r.Bloom.ApplyLocalExposure. - For gaussian bloom, local exposure is applied during the setup pass. - For FFT bloom, local exposure is applied using an extra pass before convolution. - Implemented AddApplyLocalExposurePass which apply local exposure to an input texture. #rb Guillaume.Abadie #preflight 62b5f2e8bd4bf89e21c78caa #jira FORT-460700 [CL 20812852 by tiago costa in ue5-main branch]
