  • Hi Al,

    Thank you for looking into this.

    Would you be able to let me know once you have found the solution?

    Thanks again.

  • If you use the path tracer, the caustics will work - but it may take considerable longer to get a rendering without speckles.

    Here is the fish tank model rendered with the Path Tracer rendering option: (3 HRS and about 400 passes)

  • Roy reports that Caustics has broken in the Packet Tracer (standard) rendering engine. We will fix it in a few days, For now you cannot use it except with the Path Tracer.
    (The path tracer makes nice caustics, but will take a long time to render.)
  • The error is somewhere is the caustics calculations.

    For now remove caustics from the transparent materials.

    I'll see if Roy (the engine developer) can offer some help.
  • I am taking a quick look right now (I am not in the office, but I will give it a try)
