VRay and maxscript issues

[gregvfx]

like tmp = for i = 1 to numEffects collect (getEffect i)

result:
#(VRay_blah:nameOfVRay_blah)

tmp = for i in tmp collect (copy i)

result:

#(undefined)

[gregvfx]

just tried with Lens_effects and it works, so it is a Vray render effects problem

[gregvfx]

sorry, no it doesn't work at all
Max refuse to copy render effects

I will try to find a way to get the subanim object as a workaround...

[gregvfx]

just test

copy rootScene.Render_Effects[1]

no workaround....

Please help if you can!!!

Untested, but this might work in some cases, it creates copies of the underlying ParamBlock2's and puts them in a new identical effect:

fn copyEffect effect =
(
	local ef = (classof effect)()
	local deps = refs.dependsOn effect
	for r = 1 to deps.count do
	(
		if (isKindOf deps[r] ParamBlock2) do
		(
			refs.replaceReference ef r (copy deps[r])
		)
	)
	ef
)

Then again, might not work in other cases, like effects with non PB2 dependencies.

Left work already. I was actually thinking of a workaround by creating a new effect, copy/paste the props of the old one, copy the new one and delete it to have only one instance in the CA

[gregvfx]

Thanks a lot for the help!

It almost works, very interesting this refs thing...
but if the number of PB2 is different it doesn't, without sending any error.
For example lens effect is adding a NEW block with each element you add to it.

Ok I give up on that for now, not super used anyway but frustrating.

The help file is stating in little font at the bottom of the page:
NOTE:
Unlike most MAXWrapper objects, you can not copy a RenderEffect.
