hi steve,

i'm not getting anything... checked all the light/object masks... they're all fine. which version are you using? i downloaded v4

[stevenong]

I believe I'm using v5 which is found in another thread. It will help everyone if you post your hip file to see what's wrong.

Cheers!
steven

here we go steven, thanks for the keen interest

i had a look for v5 and couldn't find it, any luck remembering the thread?

Hi artzor,

First of all, you have only a grid for the teapot to reflect & refract thus you will only see a white top. I added a box to surround the teapot which is what you see in the attached image.

Secondly, you have to add the Reflect & Refract Limit properties to the object to get more reflection bounces. Go to the Render > Shading tab of the object, change the value of the Reflect Limit to see how it affects the render. I'll leave adding properties to an object as an exercise for you. You can search the Online Help for that.

I've attached the hip file for you & I turned off the Spectral Samples & Dispersion in the shader to speed up the renders. Also, I'm using Raytrace instead of Micropolygon rendering.

As for Glass Part 5, it can be found here.

Cheers!
steven

/me sends stevenong a bagful of 'Thank You's !

hey Mario

you should just get SESI to slip this shader in to houdini , it would be great to have dispersion out of the box,raytrace and pbr of coarse

wow, this is bugging me now...

stevenong i loaded up your file (thanks for upload) and the glass shader immediately gave an error.
"This node is using an incomplete asset definition.  It will not function properly until the asset library containing the full definition is installed"

any ideas?

-edit-

the render still gives me a lambertian like result, even after i tried different reflect/refract limits.... arg!!!

You have to replace the glass shader I installed. The warning is saying Houdini can't find the shader. I would install the shader again & it should just work.

If it still doesn't work, you can set up the file all over again and learn that way too.

Cheers!
steven

[artzor]

YES!!!

thanks stevenong, working perfectly!

Hi everyone,

I'll be on a project that will require realistic glass rendering. I'm under Houdini 10 and am wondering will work under this version.  More important, what do I have to do to "install" the shader ? Do I just have to install the .otl file (the lastest one seems to be SH_glass_p5.otl), or are there more steps to get required it to work ?

Thanks
br1

Edit : Looks like I found an answer to my question in that thread :

Guess I'll have to try something else, I'll start by having a lool at those posts hereand here.
