Small update, I think I figured out the fabs math thing. <br>
<br>
If I am right here, the only thing left would be the output somehow.

Hi everyone,<br>
thanks to Dalai, who helped me, I was able to continue.<br>
<br>
The assert error was due to code inside nodes.cpp.<br>
if(color1_in->link)... and if(color2_in->link) were the
issues. <br>
<br>
So I assume that this condition is not correct for color input
sockets?<br>
I still use that for the Vector and Float Input, which seems to
work, and is done in the other Textur Nodes too.<br>
<br>
I started with the actual implementation of the Checkerboard
pattern, taking the BI Texture Node as a reference. <br>
First issue I stumbled upon is the fabs math function, it seems
this requires a float2 or 3 as input (see math_util.c in cycles
code). How should that work then?<br>
<br>
Any help here is appreciated! :) <br>
<br>
Latest patch is attached.<br>
<br>
Best regards,<br>
