I've been working at improving my use of materials,

my method is with the Revit Manual on the laptop, while I plug away on the desktop, refering back to the manual as required... making quite alot of progress.

my question is regarding the nodes, or material settings; specifically for sitework.site.improvements.fences / gates ... I have some very light colours bleeding through the bump/opacity.
should the diffuse, bump, and opacity for a texture like this be at the same scale (assuming all maps in the same proportion/size/etc?)

I have tried experimenting and I'm getting a diamond shaped tan-colour banding accross the fence, it this an optical illusion Octane is creating? or is something set up wrong?
settings are as follows:
diffuse: sitework.etc map.
Power: 1
gamma: 0.40715
scale: 0.32
Invert: Dis
Specular: 45/45/45
Roughness: 0.6684198
Filmwidth: 0
Filmindex: 1.45
Bump: Sitework.etc.cutout map.
power: 1
gamma: 2.2
scale: 0.32
invert: enabled
normal: 0
opacity: sitework.etc.cutout map
power: 1
gamma: 4.05079
scale: 0.3
invert: dis
smooth: enabled
index: 1


Any help appreciated
or any resources to better understand & experiment (preferably with examples & mini-tutorials) would be appreciated... I have taken a back seat to materials up until now; time to get serious.

Thanks,

Andrew

Hi Andrew

Would it be possible to post a screenshot of the banding pls?

Banding is possibly caused by polygon self-shadowing - there is some info in the manual on this. http://render.otoy.com/manuals/Revit/?s=rayepsilon.

The other option is that the scales of the bump and opacity maps are different (as they are in the setup you'll listed), which could give odd results.

Timtam has a lot of tutorials on youtube that go into the materials setup details.

Thanks Paul,
Cant seem to find Timtam (I didn't go through all of the pages for members starting with 'T')
Couldn't find the post you are talking about either (althought I do remember going past it at some stage in the not-to-distance past).

Can you humour me with a link to the post or his youtube page?

Thanks, A
