Atom Posted December 14, 2014 Share Posted December 14, 2014 (edited) Hi All, I am looking for a lighter-weight surface, I think the Clay surface might work, but how do I change the shader network to use the alpha from the PNG file in the Color map slot? I have routed the alpha from surface color directly to the Of and Af connectors but I see no change in the rendering. I have also routed the alpha from the surface color to Cf and I indeed see a black/white image that represents my alpha channel. I have tried multiplying the color times the alpha and routing that to Of but still no joy. My PNG file is a RGBA file. You can see from the image that the viewport pickups the alpha just fine, but the final mantra render does not. I have the Transprent bounces set to the default of 4 in the Out section.

eetu Posted December 14, 2014 Share Posted December 14, 2014 I tested this and just connecting the alpha from surface color to Of worked for me. Connecting it to the surface model's opac_int input also works, and is a bit tidier. Quote Link to comment Share on other sites More sharing options...
Atom Posted December 15, 2014 Author Share Posted December 15, 2014 Thanks for the tip, I ended up multiplying the Alpha out times the Opacity parameter to achieve a solution that worked with my specific PNG textures. Quote Link to comment Share on other sites More sharing options...
