Is there an example of how to use instancing ?

[teub]

Hello,

I've been trying to use instancing with no success (not the automatic one).

When I call RenderableManager::Builder::instances with more than 1 instance, I have a crash later in OpenGLDriver::bindUniformBuffer : "HandleAllocator.h:197: failed assertion `handle'"

I did make sure to set "instanced : true" in the material definition.

I'm not sure if there's something I forgot to do, or if that's actually a bug I should report.

I couldn't find any code that uses RenderableManager::Builder::instances so I'm not sure if this is supposed to work.
The crash can easily be reproduced in material_sandbox by calling "builder.instances(2);" in MeshAssimp.cpp, line 584.

If you have any pointer, that will help, thank you !

Trying to understand the code, it looks like a bug.
It crashes while trying to use mInstancedUboHandle, but mInstancedUboHandle is never created unless isAutomaticInstancingEnabled is true. Let me know if you want me to open an issue for this !

The corresponding issue #6579 is fixed
