Texture Layer Reflection Doesn't Work

Hello everyone,

I bought some materials and I want to use them as a terrain texture. It works except it doesn't show reflections.

Reflection works just fine when I apply the material to any cube. When I created the terrain texture from the material's PNGs, reflections are gone.

See this video where I explained the problem in detail:

The built in renderer's Standard terrain shader requires the Diffuse texture have the smoothness map (inverted roughness) stored in the diffuse texture's alpha. You'll need to copy that data into the texture yourself in an external application.

 

Thank you! Good thing is that now I know that it can be done. Do you know about some tutorial on how to do it?

 

Open Photoshop
Open Roughness / Smoothness texture
Invert the color if it's a roughness texture
Select All and copy
Open Diffuse texture
Go to Channels window, select or add an Alpha channel
Paste while the Alpha channel is selected while other channels are disabled
Save as .tga or .psd

Photoshop's built in .png file support will totally break the file, so don't use that. And no other formats support alpha channels.

If you don't have Photoshop ... I have no idea because neither Gimp nor Krita handle alpha channels as separate data channels properly.

 

Thank you so much, I solved my problem and it looks fantastic! For people with a similar issue here are some tips:

I was exporting the file in PNG which is the reason why I failed. I found TIFF and BMP working as well.
The roughness texture if not inverter might cause a plastic/liquid material look.
