I’m developing this as a product and I’m so close!
Update- grid problem is not quite solved. I have three props in my scene and one is a sky/sphere. The grids are showing up when using UE2 and converting to UberSurface did get rid of it but the downside was a lot of tweaking to get all the surface settings back to how they rendered before (still not there) and almost doubling the render times. Adding a reflection setting greatly increased the difficulty of getting rid of the grid.
The grid is actually cool looking, especially on the props I brought in from Bryce. But it ain’t workin’ now.
I realized just now that the grids are showing up on the back or inside of all the props. It’s easy enough to flip the two plane-ish objects so they face the camera (although I’d like the freedom to render from both sides). It’s the sphere that I don’t know how to flip inwards.
Post edit- the problem is inconsistent which is frustrating to troubleshoot. I’m still testing but it sometimes seems to happen in my renders after a heavy use of the spot render tool. Restarting DAZ sometimes seems to clear it up. Wacky!
Post edit-Problem solved- Raising UE2 Shadow Bias was the main key then reducing UE2 intensity and converting Sphere to either Sub-D or UberSurface (to turn off Ambient Occlusion).
