Instancing error

[Asticles]

Hi all,

I was trying to make a grass scene and I get this error:

ERROR: Singular matrix in MatrixInvert: 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1

I have managed to reproduce it on a sample scene, lowing the number of instances solves it, but I get grass holes.

I fixed the bug.

Here's an updated BlendLuxCore from current master.

(this is Windows 64bit with OpenCL. I can also offer Linux without OpenCL, otherwise you'll have to wait until the next alpha release to have the bugfix).

Wow that was fast.

Thanks!

Hi,

Have tested it and now I get a crash when stopping any render. No error on windows console.

Maybe my build has issues or it's a recently introduced bug.
It's probably best if you revert to the last alpha release for now.

Does it happen with every engine (CPU/OpenCL)?

I have tried both the version posted here and the latest, on Linux and Windows but I'm not getting any crash

[B.Y.O.B.]

Me too, can't reproduce any crash.
