About The Project

An easy to use Blender Add-on that allows you to bake Bevel Shader to the Normal Map, Ambient Occlusion to the AO Map in fully automatic mode.

If You are working in Blender, this will save you a lot of time!
If You're not working in Blender but need to bake your bevels, this will save you even more time!

Bevel Samples - Number of rays to trace per belel shader evaluation.
Bevel Radius - radius of traced bevels (in meters by default)

For AO:

AO Distance - distance of AO tracing
AO Samples - Number of rays to trace per Ambient Occlusion evaluation
AO Exponentiation - Exponentiation value of AO to increase contrast

Push the Bake Normal and Show button for Bevel or Bake AO and Show for AO
Wait... And That's All! You may save the Bake result Normal Map/AO Map in Image Window that appeared

Important additional information:

It is advisable to check if GPU Render is available for Cycles.

If not available, go to Edit>Preferences System tab In it, select the CUDA subtab and uncheck / check the boxes next to your video card name and near the processor name.

After these steps, GPU Compute will be available in most cases (If the hardware is not quite ancient)

GPU Compute for Cycles is extremely important and greatly overclocks the render, please keep in mind!

Bake AO and Show operator:

Creates the Image with custom _ao name ending
Runs default blender Bake operator with type DIFFUSE
Opens the window with the Result
