Playing with glass

[gustavobenites]

Hi!!!!

DaForce: This is the brick design. I modeled in AutoCAD with solids using booleans and chamfers and fillets to create the radius and chamfers.
In Max I detach the interior faces.



It's easy to make in Max too. But I think it's important have all tha radius and chamfers for refractions.

Taboo: I can be mistaken but I think making render at passes reflection only and refraction only can increase quality to final result independent the glossiness set to 1.0. What you think?

Da_elf: There is nothing between external and internal faces.

Thanks all!!!

Brilliant, just the information i needed
Thanks Mate

Since this is an interesting subject, i hope that you won't mind me using my abilities as a necromancer to bring this one from the dead.



I'm trying to recreate the block following the first blueprint and material tips but i can't seem to do it. Once i put a glass object with bump on it, inside the other glass box, my rays are no longer refracted.




I notice that if i increase the bumnp to extreme amounts, like 500, i only get something like a reflection on the inner part, but it's still refrected as if it was only a box.

Glass construction blocks are hollow, you'll need to take that into account in your object in order to get proper refraction.

I have, basically what you are looking at is the hollow surface on the left and the outer surface on the right.
You can see the refraction through the noise bump on the left object (it has inverted normals - pointing to the inside) but once the rays get refracted to the outer object, something weird happens.

I've attached a file in this topic.

thanks both for sharing !

Im sure it same method using Vray 1.5 for now ? or Is there new improve better setting. Please sharing here.

Thank you.

I don't have my scene files around anymore, but I don't see why the same method wouldn't work, as long as you recreate the materials from scratch for 1.5
