Hi,
I´m getting the same bug, although I am trying to render an ortho projection of a textured model in High detail. Same dialog as above, i´m adding a screenshot as well. Had no problem rendering the orthos using a Normal detail model, however, I wanted to use the High detail, so that I could see the modelled ladder hooks in the ortho, which are not that well modelled in the Normal detail.
Any idea? Thanks in advance!
