Bardage texture

[sleipnir]

Hi all

 

I have to model a couple of buildings with two of the materials of the attached picture and I'm looking for the more efficient and yet realistic way to do them. I'm talking about the bardage texture (the corrugated finishing on the top) and the alucobond panels. If I do them with a bump map I assume it won't look very realistic and with a displacement texture I will have problems in the edges.

The other option that I want to avoid is to do the grooves on the model with a subtract operation, that will make the whole model too heavy and will oblige me to redo it in the event of having to do modifications to the volumes.

Thank you

 

Diego

It looks high freq enough that I think it's worth looking at a normal map. They can give nice crisp results better than a bump.

I've had to do this a number of times and the best way I have found to do it is to model the corrugated object (I realise you don't want to do it this way). I spend hours trying to get displacement to look good when you do use displacement the rendering times are extremely long.

 

I tried a normal map in the bump slot and the displacement slot.but I found it wasn't much better. But saying that I may not have been doing it correctly. I created a normal map in photoshop.

 

Peter I wonder good you give more details on the normal map method?

I will give a try to the normal map and see how it looks. I discard the displacement not because the rendering times but because in my experience the geometry looks odd on the edges (unless there's something I'm doing wrong).

The last resort will be modeling the corrugated.

Thanks you guys
