There are some problems with vray5 lightmix?

[q976431]

I found a bug about vraylightmix. When I render the image and adjust the lighting parameters of vraylight, when I copy the lights in the scene or instance scene lights again, the parameters of vraylight in vfb2 will be invali
This is a bug? Or is it an operation that is not allowed?

I seem to find that the name of the object affects it
The option of lightmix panel changes from vraylight001 to vraylight002
At that time, when I changed the name of the light to the instance object, he would execute lightmix normally

Hello,

For the first case - instancing lights and having light mix group instanced lights - we need to generate a name for the light select that will contain data from all the lights and if they have different names there's no clear way which name to pick. So in your example after you create a new light the light select gets a new name - so the LightMix is reset.

Latest stable nightly builds (https://nightlies.chaosgroup.com/mai...ble/stable_5.1) have some fixes that try to preserve data for other lights that had no changes.

Best regards,
Yavor

Thank you for your reply
Is there a way to fix this problem? Otherwise, it will make lightmix less intelligent
For example, always get the ID? Of the parent object? Or something
Not by name
Because the name is easy to change


Test in version 30854
The same problem still exists
