Error: transformation matrix is not invertible
Error: transformation matrix is not invertible
Hello, have an error when I try to export a scene from blender, it seems that it is caused by a hair particle system which scatters a mesh on an other mesh (grass). When I have a low number of instances it works but when I set it to 200k instances the error occurs. Hope someone can help me to fix this.

Re: Error: transformation matrix is not invertible
Transformation matrixes are mathematical matrixes for rotation, translation and scaling.
A matrix that's not invertible has a determinant ≠ 0 or is not square. Why Indigo would want to invert a transformation matrix I don't know, maybe a bug.
Could it be a problem with the normals of the surfaces that you're scattering the grass on?

It is a little bit weird, I only checked the normals and now it seems to work, thank you.

Re: Error: transformation matrix is not invertible
I have the same problem now in another scene.I tested the scene with cycles and vray and they are working fine. So I think its a bug in Indigo or the exporter.I hope this will be fixed in future builds. If someone would like to test it, I can upload the scene. But it's about 150mb,so please write.
Edit: Tried Luxrender with luxcore api and that also works fine.
