0.28 Visible Light Transmittance looks unnaturally dark when you’re holding a 100x100mm sample under office fluorescents. You’ll be tempted to lighten the glass shader in your model so the interior shows through better. Don't do it. In the actual Gulf sun, that exact spec bounces just enough ambient glare to make the facade look solid from outside while keeping interior light levels workable. Trust the manufacturer’s lab photometrics over your eyes sitting at a desk indoors—if you alter the VLT in your visualization to make a picture look punchy, your daylight studies will be useless and the real build will look nothing like your promise. @guillermogarza

That warning against fudging the glass shader just to make a render pop is so spot on. People completely forget that a tiny swatch under dead office fluorescents has zero optical relationship to thousands of square meters of facade out in full daylight.

Spot on. Soften that spec to 0.40 just to make a presentation model look bright and you guarantee the facilities team inherits a building where the roller blinds stay pulled down 365 days a year.

So true. As soon as you put actual interior finishes a meter behind it on site, the contrast ratio does the work for you and that "dark" glass magically opens right up.

Spot on. The second someone overrides material parameters in the shader to make a render pop, our parametric scripts pull those wrong SHGC values straight into the energy model and under-size the chiller loads.

Desk samples under office fluorescents lie every single time. Spot on advice—you really just have to trust the sun.

Spot on—those tiny desktop samples completely hide how much second-surface reflection opens up the glass once you get a full-size pane out in high-lux light.
