Hello,
I was able to get everything running nicely with RealismSP v0.95 except for the sun. I copied the sunglowC.bmp to the LM texture folder and the corresponding suneffect.cfg to the C: LM Program Data folder. My Sun is a tiny dot. I suspect REX may be fouling up the soup. But I'm a newbie at the shader tweaks, so, can anyone suggest a possible fix? Btw, REX essentials Plus was installed and run well before I tried URP v0.95 or PTA tool. I know you're suppose to restore everything to stock before the install. But, I was thinking I was stock, having forgotten that REX may have changed the files. Again, everything else looks beautiful.
