Irradiance Particles and compatible glass?

[crazy homeless guy]

I know A&D glass is not fully compatible with Irradaince Particles, and Importons, but does anyone know if there is another type of glass that is?

...the A&D glass does not let particles/photons through, so no light from the other side of the glass effects the scene. I quickly tried a dielectric material, but at first glance, it appeared to have the same problem.

A&D glass should let photons through as long as you are using caustics rather than the shadow shader option, both offered in the A&D shader. There is a switch for that in the shader.

[L.Smith]

Yes, a transparent A&D should be transparent to photons provided it is caustic active. . . Also, the Glass phen should have no problems with that as it auto-applies a photon statement. The Dielectric shader might require a photon or shadow statement, ie. a dielectric photon or shadow shader instance, I'm not actually sure.

Hi all,

I've tried using Caustics instead of shadow option with A&D Material - and the glass doesn't pass light.

I'm working on 3ds MAX 2010 Design with all patches SP-acks etc.


Is there any possibility to get glass working with IP ?

Maybe I'm doing something wrong?

What I've done is hide the glass and cache the IP results (using Save to File and with Rebuild On), and then unhide the glass to do the final render with the Rebuild option off. With IP being unsupported in Max you are left with work-arounds, I suppose.
