Material for second UV channel

[Michael Betke]

I would like to compare purelight 1:1 against other soltions now with the trial version available.

 

I know how to export a second UV channel with arbuz exporter but how can I make it visible within the editor?

Write a shader that makes use of the second uv set.

 

The

varying vec2 texcoord1;

value is already calculated in the default .vert shader, so you only need to modify the pixel shader.

 

Just add another texture lookup somewhere and use that color however you like.

E.g.

uniform sampler2D TEX_PRECALCLIGHT;
...
precalculatedLighting = texture2D(TEX_PRECALCLIGHT,texcoord1);
...
diffuse *= precalculatedLighting;

 

And the wrapper .frag shader defines TEX_PRECALCLIGHT as texture1 or so.
