Stupid question time !
I use Blender to import satellite photogrammetry. It ends up as a scene of multiple objects all with textures overlaying the surfaces.
All that process is fine, and I can export them as a “region” for use in a World simulation
Unfortunately, the satellite imagery is subject to time of day and weather differences so varies in light levels and contrasts so dont always merge great.
Currently i post-process the textures outside of Blender to change the levels but as I batch process them I dont see the changes realtime - they end up being hit and miss and recompliing my simulator World takes 10 minutes so its a long process to get adjacent regions to blend in
Is there a way to take all those objects and change brightness, colour saturation etc.
As you may guess, i am not a Blender professional, its a means to an end for my workflow.
Thank you Blender peoples !
