[Closed] Heavy Banding when baking Redshift Lightmaps via Maxscript

Apr 30, 2019 3:42 pm

So I’ve been writing a small script that renders lightmaps in Redshift for me, but I very quickly ran into an issue where when I save the files they have very heavy banding making them unusable.

I have to use the Redshift Renderer and this is my script so far

fileName = (getFilenameFile maxfilename)
select (for g in geometry where g.name == fileName collect g)
theObj = selection
select theObj

bakeProps = theObj[1].INodeBakeProperties
bakeProps.bakeChannel = 2

diff = RsDiffuseLightingRawBake()
bakeProps.addBakeElement diff
    
-- Lightmap Properties		
diff.filetype = outputTexture = thePath+fileName+ "_lm" + ".tga"
targa.setcolordepth 32

diff.filename = filenameFromPath diff.filetype
diff.outputSzX = diff.outputSzY = 2048
diff.enabled = true

macros.run "Render" "BakeDialog"

renderBitmap = bitmap renderSize renderSize hdr:on 
render rendertype:#bakeSelected vfb:false to:renderBitmap outputHDRbitmap:true
close renderBitmap

Now, the issue is this: If I let the script run through, I get very bad banding. Example here:
