This course will look at the fundamentals of rendering in Arnold. We'll go through the different light types available, cameras, shaders, Arnold's render settings and finally how to split an image into render passes (AOV's), before we then reassemble it i

Particle instancing not working (Realistic outdoors)

Finding this new tutorial really interesting so far; I focus mainly on (very basic) non-organic modelling, so finding it refreshing having a look at paint effects (which have given me headaches before) and organic modelling.

I am just having some difficulties with particle instancing using the first grass example. I can select the particles after running the emitter for a few hundred frames, but then selecting "Instancer (replacement)" has no effect; the particles do not then emit further particles. If I continue and try and add the grass mesh as the object to be instanced, this also has no effect.

I've created a blank scene and instanced a bunch of polycubes using the same technique (emitting from a plane), which worked fine.

Any ideas why I can't seem to get particle instancing working in this one scene?

===============================

Update: actually, I've just exported a grass mesh into a new scene, and the instancing now works.

Glad you sorted it out if you use something from the tutorial in one of your own scenes i'd love to see it.

All the best
