CineRender Displacement

[Anonymous]

I added a simple displacement map to a standing seam roof surface. The surface is composed of linear lines, yet the render displaces the center of the maps. As you can see, in the render, it appears like 'spikes'. I can not figure out what setting I need to alter. or perhaps it's the map? I would appreciate the help. Thank you - Jakub Galczynski

Probably you have to increase the subdivision level....and probably you get longer render times...

First of all you need to know how displacement mapping works. you'll find an explanation here: http://en.wikipedia.org/wiki/Displacement_mapping

I attached an example of a (divided) mesh and the results. Increasing the amount of sub-Polygons will increase render-time but not really quality.
In my opinion ArchiCAD isn't the best tool for displacements.

Bernhard and Alemanda, Thank you! I was changing the subdivision level, but not to the extent I needed. I now understand the terminology, have made changes to the subdivision, and am getting good results. - Jakub

Thanks for the instructions. I like it.

I'm trying too to make custom displacement maps, to use my preferred texture. And I can't understand why I get defects evidenced in the attachment.

This are the texture settings

And this is the texture displacement map that I made by me with Photoline. Map is exactly as big as the texture image, I made it with texture image in behind.
