Lights partly won't return on Undo

[frip51]

Hi,
just deleted a large amount of data from a scene (around 180MB worth of NURBS polysurfaces after extracting their render mesh) and hit the Undo command. To my surprise, all lights except for one LightMesh object did not return - the geometry did, though.
Undo memory is set to standard (265MB), all lights (3x rectangular as well as 2x LightMesh) featured bulge maps with UV repeat values >1, in case that matters...?

I'd put that on the Bugs list, if not a known issue already.
Please solve! A working Undo command is one of the most important arguments in any application


Thank you!
Matthias

I've noticed similar problems...

When editing a 'vray mesh light' by moving it, then doing an undo/redo I either lose the light or get a duplicate.

This isn't a horrible bug, but one that should be easy to replicate and fix

Thank you for reporting this. I'll look into this.
We hope to have all issues with Mesh Light operations resolved in the upcoming v3.6.

Kind regards,
Peter
