Preparing lights

I have a scene that is crashing. I replaced the lights, reset V-Ray, but it will not render. IPR does nothing and bucket is crashing with this error.

marker is at C:\builder\cgrepo\vray\vrender\src\vrenderlight.cpp, line 643: Preparing lights (VraySun.hdri0037)

Same project and new error.
EXCEPTION: Preparing instances
Last marker is at C:\builder\cgrepo\vray\vray\src\vrayrenderer.cpp, line 3484: Preparing camera sampler

I merged into a new scene, but still crashing.

Any ForestPro objects? This was crashing it for me even with the latest Beta from yesterday.

Yes, many. I’ll delete them and see if that changes things. New sun, camera, and still crash. I’ll delete the forest items to see what happens. Thanks!

Yep, that was it. I turned all my Forest items off and it rendered just fine. I upgraded to V-Ray Next and now FP doesn’t work. The forum said that they’ll come out with a final in a couple weeks, which just isn’t good enough. I think a lot of FP and RC users will be surprised when all their scenes break. Hopefully, since we have a long weekend, it’ll come out early next week. The funny thing is, it broke this morning before I downloaded and installed V-Ray Next, so why it stopped working when it was working with the beta, I don’ know. Thanks for pointing me in the right direction. Multiscatter is working so I might rebuild my FP in multiscatter.

It looks like it’s up on the site now: FP 6.0.8 support V-Ray Next final (v4.02.04).

How funny, it just came out!

Strange. New project and same crash, even with the latest FP beta. Is anyone using FP with V-Ray NEXT?

It took a few hours, but it wasn’t Forest Pack, it was Laubwerk. Always something!
