>>7592I don't know anything about version 14.6, but yeah, like I said, give 15.3 another try AFTER going back to 14.4 first. I remember when I tried updating to 15.3 directly from 14.9, and the issues remained. But when I did a clean install back to 14.4. all the shaders and shadows/etc were back to their former glory! And it remained fixed when I updated to 15.3 aswell.
Before i did all that though, friend linked me to these shader files from singularity to stick into firestorm

I was stuck with shaders in advanced lighting busted since back around November, and boy does it feel great to have everything working again So I wish you luck in getting it back in working order so you too can enjoy a SL with fancy lighting, shadows, and nametags,texts, and selection highlights working how they're supposed to work
