From c418467c03db916c3e5312e6ac4a67365e196dbd Mon Sep 17 00:00:00 2001 From: random_thoughtss Date: Wed, 19 Oct 2022 15:09:43 -0700 Subject: [PATCH] Don't compute latent mask if were not using it. Also added support for fixed highres_fix generation. --- modules/processing.py | 70 ++++++++++++++++++++++++++---------------- modules/sd_samplers.py | 4 +++ 2 files changed, 48 insertions(+), 26 deletions(-) diff --git a/modules/processing.py b/modules/processing.py index a6c308f9e..684e58332 100644 --- a/modules/processing.py +++ b/modules/processing.py @@ -541,12 +541,8 @@ class StableDiffusionProcessingTxt2Img(StableDiffusionProcessing): self.truncate_y = int(self.firstphase_height -
