Author Topic: Export and visualize particular channel  (Read 135 times)

Hi,
I need some help for visualizing and exporting materials from Designer,
I need to build material and export with a particular set of channels for a game I am working on.
On painter is more simple to setup custom export but not in Designer.
I need to export 3 file
1 is the diffuse = RGB Channels for Base Color () + Alpha for Opacity
2 is the metallic= Red channel for Metallic - Green channel for AO - Blue channel need to be black + Alpha for Smoothness
3 is the Normal= Red channel need to be black - Green channel for Green  - Blue channel for Blue + Alpha for Red channel.

Now when the channel needs to be blank what setting should I set in the usage field? then I need to send red channel on alpha how I can do that?
Another question I add an alpha channel as a test on opacity for the diffuse map that need an alpha and use the Channels Shuffle to mix but it doesn't seems to work.
Generally speaking  I can't see the render in 3d view of the combination of all this element, what I doing wrong, can I do it?
For Diffuse

For Metallic

For Normal

Thank you
Fabrizio

The 3d view totally ignores multiple usages (these are mostly meant to be interpreted by integrations)., our default shader is made to take a single texture for each sampler.

You'll have to modify the shader to take a packed texture as input.
