Photo rendering does nothing

[Gateway01]

I'm using SweetHome3d v7.5, photo rendering 2.3

When I try to render at level 3 or above using either renderer the timebar just flashes and then does nothing. With a different model using the same setup it works fine.

Any ideas where I should start looking please?

If it's a large model - increase mmeory (Xmx trick - see FAQ)

If it's a faulty model
- delete half of your models - try
- if it works - undo - keep halving, until you have the faulty model

I've subsequently found that it does work if I use the toolbar icon but not if I use the menu.
