Global switches: Reflection/refraction

[cheerioboy]

Is it possible to disable reflections & refraction - but still allow for GI/Light to pass through those objects?

I want to render a scene without reflections and refraction, but when they're turned off it makes the whole scene darker. Current solution is to remove glass objects from being visible to GI. Is that the only option?

Thanks

Another approach could be to enable Override Mtl with Opacity map and use the "Exclude" list to include only the glass objects.

I'm now baking another scene project where the glass affecting the GI is important to the lighting of the interior. So I can't exclude the glass from GI. I need a way to render the scene with reflection/refractions turned off (so they don't appear in the baked complete map), yet still hold their reflective/refractive properties when it comes to how the GI is calculated. Does that make sense?

The other option is to bake out the GI & Lighting and combine them in post.. for all 280 baked objects

Would it be possible to just turn off reflections and keep refractions? maybe that would be enough..

Thanks

turn off reflections with this - http://www.scriptspot.com/3ds-max/sc...terial-control

I always switch off reflections for GI, but leave refractions on. makes it so much faster.

Can you point this out, I am not seeing the option?

Oh, Jah! I do this for tree and bushes. Do you do this on everything?

for the irradiance map, yeah. takes 1/5th the time of doing it with reflections on, so for interiors you can do them on high and get that crisp bf-like detail levels in a couple hours.
