Single sided or "thick glass"?

For single sided:

make the material fully transparent (If you want a colour to it, you could put it somewhere between 0-5% transparent) Add a reflection layer to the material - with Fresnel map. Adjust the Refraction value so it's not completely black, value 30

Also, I dont know too many people who would give up all their V-Ray secrets for free. 😉

is this useful? (worthy to translate?)

Note that once the IR is as good as you want it, if you choose to render twice the size, then you can reduce the min/max by one. If you render four times larger you can reduce min/max by four.

Since I didn't have the maps you used I just rendered a clay model, and I did not see the faceting...
hmm..

I surrender! It's haunted! Call ghostbusters!

I tried everything. Resetting the settings. Even removing the V-Ray data from the file and setting it up again. Nuffin'!
I'd suggest you hand it over to ASGVis and let them look at it.

You just revived 8 years old topic 😄

Ok guys, i found what the problem was. I just removed all the textures in the model and the render took only 5 minutes.
Thank you all. Now the question is, how am i going to make the scene look realistic, if all the textures are removed from the model?

aha, I got it 😄

again thanks for the reply and advices, my problem is that i don't know anything about photoshop, you know any kind of tutorials regardings this line of work?

regards

I don't know how to fix your issue, but I do like your name... 😉

Nope, not really, but you can try to figure this in mat. editor, updating the material look. This is the reason that some users shared the settings for the pool water( being asked by others), maybe another user will jump in to help.

If you don't have a 360 environment bitmap then add the sky in post - Photoshop or similar. That's what I most often do.

Ok, so if I were wanting to make a bottle that is red and I wanted to apply a label. Listed is what I would have to do?:

make bottle and paint red import texture and apply the label image. in V-Ray material window, select diffuse tab, click transparent and make white. in diffuse tab, click "m" on transparent select bitmap on common drop down. click "m" in bitmap and select a grey scale of the label graphic.

And that's it? I must be missing something. When I do it like this, the bottle turns transparent red.

@thomthom said:

Yes, V-Ray samples dark areas less.
Is it suppose to be so dark?

If note, I'd adjust the camera exposure - if you're using the Physical Camera.

Thanks Thomthom for the exposure advice, I will check that out. Should I just up the samples then to cure the darker area blotchy effect? That area to the right of the scene is not supposed to be that dark. There are plenty of windows from that side of the room to illuminate the room in the actual house, so I'm trying to keep it consistent in the render.

Chango, I will have to try your tip with larger plane lights. The only thing, when you use 'no decay' does that take away from a more realistic render?

I was thinking about using point lights under the recessed can lights instead of small plane lights, I think that might give me a brighter render.

You can use my V-Ray Toys plugin. That will assist you to setting up matching views so they fit 100% when you merge V-Ray and SU exports.

Follow the Plugins links in my signature.

thanks a bunch 👍

Thanx Thomthom and Holmes for your help, appreciate it.
You actually dont need to play around with the alpha
-in Environment tab in BOTH the Sky and background tabs, choose bitmap and place your HDRI.
choose environment as opposed to Texture on the top

Put your physical camera off and render!
you'll probably need to adjust your blur and multiplier values, as your first rendering will most likely be too dark or too light and blurry.
Jorge Barrero's 'V-Ray for SketchUp Tutorial - Sun & Sky - Beginner' on Youtube explains it nicely.
thanx again
