Translucent / frosted Glazing ?

Anonymous — Thu, 11 May 2023 11:56:51 GMT

So I want to create a partitioning wall in a reaustraunt. I think that a glass wall will be a good choice but I don't want the glazing to be transparent for obvious reasons.

How can I make the glass translucent or ' frosted ' similar to the image below ( not my image )

Thank You

Apply an image of tiny white dots as a texture with the interstices between the dots masked transparent.

The dots confuse the rendering engine to produce translucence.

What do I apply the texture to ?

Thank You

Following your instructions, here's what I got...

As you can see it isn't translucent but I did select the option in material attributes... unless it is the image I have used.

"Masking" means creating an alpha channel in Photoshop to create transparency in Archicad.

The easiest way:

In photoshop, select the dots and apply a Quick Mask.

Saved as a tiff or PSD, the masked part of the image is told to be transparent in the material dialog.

Hmm, Still not sure if it is right.

It does seem to be slightly more translucent in the photorender projection ( if this is where the texture alters the render ) in normal 3D it is just dots.

I appreciate your help on this.

Show me screen captures of:

• material settings in the internal engine

• the four channels of your dots image.

The dots image is a greyscale...

Here's how I did it:

Converted the dots image from Bitmap to Grayscale ( using a 25% grey, changing the frequency, angle and shape.

Duplicated he Background layer - The background layer cannot be transparent, so I created an new layer that can support transparency. I then deleted the first background layer, keeping the duplicate

New top layer selected, > Add Layer Mask

Option-clicked on the mask icon

Go to Image > Apply Image and apply the Layer image onto the Mask...

Clicked back on your Layer icon in the Layer palette. The dots should now show transparency (checkerboard pattern) in the background area.

Filled the Layer with White so that I have white dots on a transparent background.

Show me the channels.

What file format is the image?

Its a .tif file.

I'm assuming there needs to be more channels as I only have one... ( greyscale ) ?

Thank You

What else could be causing the problem... Still not managed to get it working.

I've got it working - Here's a screen-capture of the material (surface settings).
I'll post the actual 'polka-dot' files next

Polka-dot file below. The PNG file format allows for transparency without being as bloated as a TIF. It's white dots, with a transparent background... which is white, so you'll have to trust me - it's there.
Just right-click and save as...

Looks like it's set up to tile easily.
I'll give it try later.
Thanks dv_chris

If you drag the mouse across the middle, it will highlight the image area, to set up for the "save as".
(Also seems to open OK in Paint.net)
