Subject: influence of altitude


Javil ( ) posted Wed, 25 March 2015 at 1:05 PM · edited Wed, 14 February 2024 at 3:40 AM

Just trying to understand some functions which I never used (enough) before.

One of them, influence of altitude. If I have 2 colors mixed and have a strong influence of altitude, nothing happens if I raise the cube further up in altitude in the air (z)?

Any idea why nothing is happening?

See example, where the simple rectangle is moved to a higher altitude..

I think it refers to the altitude on something.  I often use that to get snow on the peaks of a terrain

Can you give me an example how you do that? If I want snow on a peak I can control that by only playing with the mixing properties, not with the infuence of altitude..

This is my snowy mountain material - I can alter the distribution of the snow either by using the altitude or slope range constraints

Thanks.

I don't think Environment altitude is the same as Influence of altitude. Excuse me if it is.

I can perfectly determine an environment altitude on my objects, but I wanted to know what Influence of altitude does..

When I play with the Influence of slope, rotate an object, I see visible result. When I play with the Influence of altitude nothing happens..

See the options I tried:

Maybe I should explain my main goal.

I'm trying to make a material that reacts to the altitude or the current height that is on.

To give an example, in this example picture you see a sphere with 2 colors. If I lower the sphere in altitude (z) I want the distance between
the red color of the cube and the yellow of the sphere to be the same.

So imagine the distance of the red color of the cube and the yellow color of the sphere now equals 10 cm, I want it to stay 10cm if I raise and lower the sphere in z.

Hmmm - never tried that to be honest.  Good luck getting it sorted out though.  Have you tried posting in the e-on forums?

One possibility is to plug the Decomposer 3 node into Position and just extract the Z parameter to get height and then use it to drive a filter function with a blender node.

The other option to the decomposer is the Altitude input function as it has "Relative to sea" option - never tried it though.
