VRay 3 vs VRay 2.5 - Maxscript changes?

[Morne]

Hi all

Was there any changes to the maxscript names for things in VRay 3 compared to VRay 2.5?

I understand VRay 3 has extra things, but will ALL functions etc that's in VRay 2.5 work in VRay 3?

Except for lc number of thread which is now automatic.

Things should work the same, yes. Even if we have changed any MaxScript names, we usually add aliases with the old names for compatibility reasons.

Best regards,
Vlado

Good to know

What code can I use to switch off max ray intensity, probalistic lights for 3, but to tell 2.5 to ignore it?

Something like if maxrayintensity =! undefined, then swith it off, else just ignore it

Try just doing something like vr = renderers.current and then showproperties vr to get a whacking great list of all the access methods vray has to maxscript - I think it's something like "options_maxrayintensity" or some such.

I have this:

if renderers.current.options_maxRayIntensity_on != undefined then
(
    renderers.current.options_maxRayIntensity_on=false
)

But VRay 2.5 gives me an error

It should work for 3 to switch it off, but I also want it to work for 2.5 to just ignore it since 2.5 doesnt have that feature
Same thing for

.options_probabilisticLights

[joconnell]

Normally for this type of thing you'd wrap the command in a try and catch statement.

[Morne]

so then this should work?

try(renderers.current.options_maxRayIntensity_on=false)catch()

Is that correct?

For 3 it should switch it off and for 2.5 just ignore it, or return "undefined" in the listener without an error

[joconnell]

Looks good alright, tried it under 2.4 and it just returned undefined instead of erroring and came back with false under 3.x.

Cool thanks John!
