Is there any way for optimisation of shadows at runtime. Looking for something like update shadow map only if it is needed ( surface caching ) or any other way for increase performance?

Anyone? There should be way for this to be done.

There’s nothing in place to do so right now, but makes an interesting feature request. Feel free to post one here: https://github.com/away3d/away3d-core-fp11/issues

I thought that for static objects there is a way to achieve optimisation. I’ll submit a request in github.

For static objects you can generate lightmaps using your 3D software (3DSmax, Maya etc ).

The main problem will be that in most cases it’ll require a second UV set, and that you won’t be able to export a mesh with 2 UV sets (or it’ll export fine but you’ll have just one UV set).

You’ll have to export 2 versions of your mesh, one with the regular texture UV set (for example a tiling floor or wall, which repeats) and another one with the lightmap UV set (which doesn’t repeat, typically).

My objects are static in the scene but they are dynamically generated. Shadows are too expensive that’s why I asked for optimisation at runtime.
