Can you share your slang file to compare? I have only done replace the first shader (stock) in guest-advanced file and copy xbr-lv2 shader to shaders/guest/advanced path:
shader0 = shaders/guest/advanced/stock.slang
filter_linear0 = false
scale_type0 = source
scale0 = 1.0
alias0 = StockPass
TO
shader0 = shaders/guest/advanced/xbr-lv2.slang
filter_linear0 = false
scale_type0 = source
scale0 = 3.0
alias0 = StockPass
There isnt pre-x factor scale on xb2-lv2 or i dont see…
