i am making a logo reveal which involves a mountain which then quickly spins around to reveal the logo on the other side. i used the landscape tool to create a mountain i am happy with but it is missing a very critical piece; it needs a texture.

i am trying to get a snowy-on-the-top and rocky-on-the-bottom type of look. the mountain itself has a number of ridges going out from it so i cant just use a gradient. i know there are some plugins out there but i dont want anything that i have to pay for.

to sum it up, i want snow on the top and rocks on the bottom and i have no idea how to do that.

I think the best way to do that is to use the effects>terrain mask shader as a layer mask inside of a layer shader. The terrain mask basically allows you to create a gradient based upon height and slope. You can combine multiple masks and other shaders to place different materials on water, steep walls, mountain tops, etc.

Example: 6073_terrainshader.c4d.zip

thank you for the example, but i am still kind of new to cinema 4d. do you think you could explain a bit better how you got the different objects to look so different. all i see is a whole lot of layer masks with gradients and different textures underneath. i have no idea what any of it means.

If you click on the layer mask shaders you'll see the properties pop up in the attributes manager. That should help a little, but it's hard to explain in a post. I'll try to put together a video tut tomorrow.

Thank you sir. Also could you explain the advantages/disadvantages of using multiple masks and layers

thank you so much, just one other thing. can i use the terrain mask on an alpha channel set to a low altitude and slope as an area to generate trees in. like if i only wanted trees below 100 cm and only on slopes less than 30, how can i make trees generate using the remaining area as a base? can it even be done?

edit: by trees i mean low quality, exact replica pine trees

What I would do is put the sprite trees in a cloner and then use the shader effector with the terrain mask to control the visibility of the trees. Example to follow.

Thank you. This sounds like just what i wanted, a whole bunch of tree copies in areas defined by a terrain mask.

So after looking at this it seems that the shader effector can't use the terrain mask directly; you have to bake it to a bitmap. Here's a scene file for you to play with:

once again, just what i was looking for.

however me, being quite new to C4D i have no idea how the cloner tool works. do you think you could point me to a good tutorial covering the basics because it looks a bit complicated.


also, just to clear some things up about the scene you sent me:

1. the baked terrain mask is just a white colour, then a terrain mask with the settings to your liking, then a black colour which is then all baked together in a process that i am ignorant of.

2. how does the cloner use the terrain mask? i couldn't find any way that the two connect.

3. why is there a water texture and where is it applied? i couldn't really find out.

There's an excellent series of mograph tutorials on this site by Mylenium. I suggest you check them out: http://library.creativecow.net/search.php?q=mylenium

The Cinema help docs are also an excellent resource.

ok, so i think i am done, but i still cant figure out how to convert my terrain mask to a .jpeg/.png from cinema. help?

Create a material with the terrain mask in the color channel and place it on your landscape object. Then give your object a Cinema>Bake Texture tag. In the tag properties, set a file name/destination. Check the color box in the details tab, and then click the Bake button. Simple as that.
