Description

In a Linden Homes houseboat with a Mirror(Everything) mirror probe on a wall mirror, the internal steps inside the houseboat show as a ghost flattened image on top of the stairs top platform. Expectation is that mirror image reflects what is really there in the houseboat interior.

Note that if the Mirror(Everything) probe is removed and the reflective surface picks up a normal box reflection probe for the internal volume then a clearer wrong flattened image of the stairs appears in that reflection. See attached image "Normal RP on Houseboat shows flat steps.jpg".

Reproduction steps

  1. Go to a Linden Homes houseboat and go inside.
  2. Observe the 3 steps internally that lead to the lower level
  3. Set up a reflective surface on the wall where the steps will reflect.
  4. Set up a box reflective probe (NOT a mirror probe) for the internal space of the houseboat.
  5. Observe the reflection of the steps in the reflective surface. Note they are a flat image.
  6. Add a Morror (Everything) probe to the reflective surface.
  7. Observe that the reflection has changed but from some angles a ghostly image of flattened steps shows on the top surface of the steps area.

Closing as cannot reproduce, feedback from LDPW was that they could not replicate the problem and all the mirror reflections appeared correctly.
