Wall Disappears when rendered

Dave Seabury — Tue, 07 Sep 2021 20:54:45 GMT

Haven't seen this one before and I can not figure out what is causing it.

modeling some tile on a shower wall. The tile itself is a separate wall place

on the framed wall. The first image is the 3d window, the tile section on the

left is 1/32"off the other wall form, the one on the right is touching the face of the

other wall and it is gone once rendered. Any ideas?

Thanks David3d windowrendered

The result looks like expected 😄

But in good earnest:

The issue you're confronted with is the typical thing that happens when two planes are at the same spot: The computer calculates the z-depth (the distance) of the polygon to the camera. Rounding errors will lead to the result that some polygons are more closer to the camera than others and vice-versa. Thus you're ending with a botched up picture.

tl;dr: Move one plane out of the other.

Do the wall reference lines overlap?

That is to say, if the tile "wall" reference line were on the outside face, and

you didn't do the 1/32" offset, does it still happen?

Just give them thickness? And If need be SOE them from the wall?

Thanks for all the suggestions, they all worked on one wall but not on another. In the end i created a new profile wall with a tile backer and a finish surface for the tile, then SEO'ed that from the frame wall and it seems to work. Thanks again for the suggestions.

I thought I had this figured out but I don't. Is it possible for a texture to cause these issues or a rendering setting? Everything is perfect in the 3d window But i get this when rendered. The lower wall is a complex profile that i duplicated and changed the surface material. No issues with the lower one.

Thanks Again for any suggestions.

It appears to be the texture. Opened the profile and changed to a different tile texture and it rendered as I would expect. Now I will see if i can chase that down.

Solved. This Texture had a Displacement Channel and once turned off The wall renders correctly.Displacement turned off
