energy preservation in old scenes

[Jiri.Matys]

Hi,

new energy preservation in VRay 6 works only with newly created materials. But can we convert all the materials in the scene with vray scene convert or with some other option so all materials in the scene use this new behaviour?
Thank you.

It's possibly something we could add to the scene converter, indeed.
for now, running this line of script in the scene will turn EP on for all materials.

for m in (getclassinstances vraymtl) do m.option_gtrEnergyCompensation=true

Notice it has no error trapping, so running it in versions other than 6.0+ will simply fail with red text in the listener.

Ok, great, thank you Lele.
