I'm trying to create a material like this: http://www.istockphoto.com/file_thumbvi ... -metal.jpg
I have al.nk material with bump-map that looks pretty much like that, but I'm finding it difficult to get subtle enough grooves, as the lowest allowed value for bump-map depth in blendigo is .01 mm. The image I'm using has already very low contrast.
Here's what I've been able to do so far:
brushed aluminium

Looks intimidating...
Guess I'll just settle with adjusting the b-value manually in the indigo scene file.

Re: brushed aluminium
you could also try to use your bump map as a Exponent map (without bump mapping at all!)...
this should generate a more subtle effect.

Using ISL you can control values way lower the Exporter based limit...Silmä wrote:...as the lowest allowed value for bump-map depth in blendigo is .01 mm.

Re: brushed aluminium
Which is way above cindigo for example where you have 1mm at best, still it should give you plenty of room for real scratches. Could you post the material as pigm?Silmä wrote:I have al.nk material with bump-map that looks pretty much like that, but I'm finding it difficult to get subtle enough grooves, as the lowest allowed value for bump-map depth in blendigo is .01 mm.

Re: brushed aluminium
Put it in the Material Editor, the values go much lower.

Re: brushed aluminium
I would never say that with low contrast sketch map in the 0.01 mm region would make that severe bump...Soup wrote:Put it in the Material Editor, the values go much lower.
Re: brushed aluminium
Apparently it was an exporter related issue. All is fine after updating from Blendigo 2.2.11-b to -d.
