forgot to add that the lpe c.* also dont include the GI

its also seems to work with brute force bbrute force but not with lightcache.

addendum.

brute force brute force makes lpe work but not lightselects and lightmix still separates the gi into the rest channel

Hi, just gonna add that’s not only GI not working, it’s all secondary rays (single light, light select set to “Full”):

RGB render:

Light select (as the dome is the only light, the light select should be an exact copy of the RGB):

Hi,
@LeoYfver , it looks like the mode select is broken, not the “Full” mode on the light selects, if you try to force the “Full” mode via post translates you can fix it (at least for now until the Chaos guys fix it properly).

import vray

from vfh import vfh_utils

renderer = vray.VRayRenderer()

for plugin in renderer.plugins:
    if plugin.getType() != "RenderChannelLightSelect":
        continue
    plugin.light_select_mode = 4

And thanks @chakarov for the code (initialy was supposed to fix the light mix, but I noticed this is the same issue as the one in light mix and just removed 2 lines).

​

Best,
David.
