Bug: VRLightMtl w/direct lighting enabled hangs XrefScene

[cgrant3d]

VRayLight Materials that have the "direct lighting" checkbox enabled cause problems when XRefScene'd into a master file.

To demonstrate:
- Create a sphere w/VRLightMtl and enable "direct lighting" checkbox.Save file.
- Reset max / new file. Jewel / Refereinces / XRefScene / Add then select your previously saved file.
- Render and it'll hang on "transforming vertices".

Just updated to the latest VRay for 3ds Max 2012 (2.20.03) last week...

Quoted for agreement, thanks for posting this, helped a ton. Hope this gets fixed soon.

here's a workaround if you don't need the direct light enabled in your scene and can function with them turned off. run the script to kill the direct light in all your vraylightmtls will at least get you rendering till a fix comes out.


for o in geometry do
(
if classof o.material == VRayLightMtl do
(
o.material.directlight_on = off
)

if classof o.material == Multimaterial then
for m = 1 to o.material.numsubs do
(
if classof o.material[m] == VRayLightMtl do
(
o.material[m].directlight_on = off
)
)
)

Easier than that...

for o in getclassinstances VrayLightMtl do o.directlight_on = off


Thanks for bringing this to our attention, we often use XRefScene so we've probably come across this bug too.
Happens on 3dsmax 2011 with Vray 2.2 too.
