I thought it would be difficult to fix but it turned out to be a 1 line difference - I just had to move the lights mesh to make sure it's rendered after those crystals. You can redownload the updated mod from my previous post, should be fixed now. That one I'm not sure how to address since that bridge is a different object altogether. I don't really know how to handle that. It's mr_016f_kouseb in MR_FINALEGG. The outer glow is mrd_032s_efhikari (turns out this one uses a very simple transparency mask - the darker the pixel, the more transparent it is. You can make it more vibrant by basically brightening up the image). Try playing around with it and see what happens if you make it darker or lighter. It might be enough to just brighten up the black parts. You can edit the PNG files directly in the mod's texture pack folder to save time. You can also confirm which textures are used by different parts of the model by checking the materials in SAMDL.
