HDR in Vizard

[student]

Hello,

I want to simulate the sun blinding when you look at the sun trough a window. I tried to do it by placing a spotlight behind the camera, that faces the sun and gives a specular reflection on the window. It's a nice effect but it is not real enough.

I read about HDR rendering and that's exactly what I need to make it very realistic. But all information uses C++, and I can't find any info on how to do it in Vizard.

So the question is, how can I use HDR in Vizard 4?

Thanks in advance.
