Eyes bump maps

jwcjaygaines

Hello all! So I'm having an issue with a Daz model that I transferred over to Blender. In one of the animations I created, I noticed that the Bump map of the Irises, Sclera, and Pupils (which all use the same texture) was causing their eyes' reflection to "flicker" whenever their head moves. I generally try to keep all the default maps upon transfer and leave them plugged in as-is, with some minor tweaks here and there. So should I just completely disconnect the Bump map from those textures, or will this cause further issues down the road? I'm sure it's a simple answer, but the 332 frames I rendered earlier took 5+ hours, and that was WITH minimizing everything humanly possible. I don't want to re-render the region of their head, only to discover that the glistening-flickering problem still persists. Again, I'm sure some people are going, "Well DUH!", but I just wanted to make sure before I do it. The scene is 1920x1080 using Eevee, if that helps, and the lights are a mix between Area and Point. It's a night scene, so I resorted to no HDRI, thus, the scene is using just the lights I added.

Eevee is a screen space engine, including reflections, this means it only takes into account what's visible in the viewport so reflections may "flicker" on various occasions. There's lots of tutorials explaining how to deal with this.
