Title: Quick question about displacement equivalent feature
Post by: lupaz on 2016-12-27, 16:38:17

Hi there,

I was wondering if now a days there's anything better than displacement.
Maybe a feature I'm not aware of...
Specifically I need to create wood siding in a house.
Like for example this: https://www.google.com/search?q=wood+siding&espv=2&biw=1920&bih=960&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi6h6vj2ZTRAhUC0IMKHcqZCt4Q_AUIBygC#imgrc=o6BZ60S-SlP1pM%3A (https://www.google.com/search?q=wood+siding&espv=2&biw=1920&bih=960&source=lnms&tbm=isch&sa=X&ved=0ahUKEwi6h6vj2ZTRAhUC0IMKHcqZCt4Q_AUIBygC#imgrc=o6BZ60S-SlP1pM%3A)

Thanks.

Not that I'm aware of.

Depending on how often you'll need to do this and how complex your facades are, I would use iToo's railclone tool: https://www.itoosoft.com/railclone.php (https://www.itoosoft.com/railclone.php) it works like a charm and the support on their forum is spot on.

You could probably do it with the new Max Creation Graph found in max 2016 and up, but I have no experience with it.

I often use splines and a sweep modifier for these operations. Extremely flexible. Just add\remove extra vertices to delete window and door openings and work your way up.

Yes. The splines sounds good.
I'm not in the mood to learn a new plugin :)

Thanks to both.

For wooden sidings I've found a free photoscanned asset with texture. It's kinda high poly (expected) but it looks very good. You can always detach the 4 planks like I did and scatter them around to make it less repetitive. I used it with corona and unreal and it looks pretty nice. www.remnantstudios.com/scans/pick-a-siding (http://www.remnantstudios.com/scans/pick-a-siding) I ended making my own texture though because this one isn't very flexible. By the way there are a lot of free photoscanned assets on the site, worth bookmarking!

Actual 3d asset :

On a side note,

I've used parallax occlusion mapping a few times but with real-time engines. I Wonder if that technique would work (or would be beneficial) with offline renderers. I know parallax does not introduce new geometry, it's all in the shader. But it can look pretty damn good imo.

This travertine use this technique : (not my project)
