Bumpmapping Shader

Discussion and feedback on Construct 2

Post » Wed Aug 29, 2012 8:53 pm

Greetings,

I was wondering if someone could offer a bit of an explanation about how this effect works and how to use it. I have some familiarity with 3D shaders - wherein a single object would have multiple textures (e.g. diffuse, normal, specular, etc.). Obviously in 3D, these effects work in coordination with a static lighting system.

In Construct2, we don't have a lighting system. What are the parallels, if any between, bump map effect in a 3D environment, and the bump effect used here? What kind of images will produce the best results? The pipeline I am use to would be such that I would take an image, bring it into photoshop, and then use the NVidia plugin to generate a normal map.

So far, I have not been able to understand how to use this effect in any of the way I am accustomed. Any help and insight is greatly appreciated.

Thanks!
