Tip of the Day #14
Today's tip of the day will show you how to blend two different images loaded into the reflectance 0 and 90 slots using the R2 parameters.
Step-by-Step:
1) Load two different images into the reflectance 0 and 90 slots and set the roughness to 50 (you do not turn on Force Fresnel for images)
2) Enable the R2 function with setting at 0 and 50 – this will give a 50% blend between the 2 images.
You can lower the R2 roughness to shift the percentage of blend in favor of the reflectance 90 image – conversely you can raise the R2 roughness to shift the percentage of blend in favor of the reflectance 0 image.
The following image shows the R2 roughness set at 0,25,50,75, and 100 in order.

You can also adjust the BSDF roughness which will adjust the blending curve. At roughness 50 the gradient between the two images is linear -- however as you lower the roughness the reflectance 90 image will become more dominant and conversely if you raise the roughness the reflectance 0 image will become more dominant.

Jason.
