Tiling for image versus bump

3dOutlaw

For a surface, is there a way to increase tiling of a bump map, without changing the timiling of the diffuse map?  

If not:

1. This would be a good new feature!  :)
2. Anyone know an easy way to take a bump map, and seamlessly make it 50% "smaller" in Gimp or something...?

For Iray materials the answer is yes, but for 3Delight, it's no.

Each image property in an Iray material has an individual tiling function.  You access it by clicking on the image icon, selecting Image Editor (not LIE) and there should be an instance tiling tab...

Brilliant, off to check that out now!  thanks!  :)

Update:  Worked perfectly!

For which render engine? Iray, using the Iray Uber Shader at least, allows per-map tiling; the 3Delight shaders don't though it can be added in Shader Mixer using multiple Tiler bricks, one for each map you want to have its own tiling (but make sure you give them unique labels)

I think you need to change the name, too, not just the label...at least I've been changing both.

I knew I asked this before, so here is a resurrection for a follow-up question!

If I have a shader (in this case for fur) that uses a horizontal and vertical tiles of 3 (for the fur), but I want to use my own image...can I "back out" the 3 by using the horizontal and vertical in the image editor of the image map only?

I tried setting it to 0.25 (thinking x2 = .5, then x2 = 1) but it failed, and trying to figure this out wihtout trial and error is not my forte  ;-)

Are you saying that the general tiling is 3, and you want to add a spedific map that only uses 1?

Resulting tilling is Image tilling times General tilling,

So if you want a resulting tiling for that image of 1 with a General tiling of 3, the Image tiling must be 1/3=0.333

OK, thanks I'll give it a shot.
